Why can't you use regular GE silicone 1 vs. this product?
Wondering about the differences in product
Below is a link to the GE website for their home use caulks. The FAQ’s ask about use in pools, bath, or boat and it recommends not to use below the water line. They don’t have a technical data sheet on their site, so I can’t look into this much further without that.
Between their usage statements on the actual product about not using underwater and additives that we are unsure about, we would not recommend it’s usage on aquariums

Small crack outside tank
I heave a small crack outside the tank. It doesn't go all the way through it about an inch long center of the tank. Maybe half way through the thickness of the glass. Can this deal it and keep it from spreading?
No, if there is any kind of a crack in the tank, the tank should be replaced.

Is it safe to use Marineland sealant to glue coral to reefs?
No, not at all. There are many safe ways of doing this, but silicon sealant is not one of them. Check at your LFS.

Will Marineland Silicone Sealent adhere to plastic under water?
It would likely work on the plastic, but the plastic would have to be primered first, or it won’t stick.
It can’t be “applied” under water, but after it cures it would be fine under water.

Is Marineland Silicone as strong as Momentive RTV
I need to reseal my 120 gallon and bought several tubes of Marineland silicone to do so, but now I see that most people recommend Momentive RTV. Can you send me a tech data sheet on your silicone so I can compare the two.
Unfortunately, we do not have a tech data sheet that we would be able to send out. I'm not familiar with the other silicone you are referring to, but as long as the silicon is for aquarium usage, it should be safe and effective. Make sure to remove ALL old silicon first and have a very clean surface to apply new silicon to. Allow to cure for 48 hours then test it.

Aquarium Sealant 100% Clear Silicone Rubber
Is the Marineland Aquarium Sealant odourless after curing? Is it safe if touched after being cured?
Marineland Aquarium Sealant may release some odor during the curing process, but afterwards there will be nothing. Also we do not recommend that you touch the silicone during curing, to avoid creating any bubbles, but it is not toxic to you if you do.

What is the temperature range of this product? Is it food safe?
I plan on using this to seal a mash tun (tool for extracting sugars from grains when brewing beer) the mash water will be up to 180 degrees fahrenheit and i need to know if your sealant is capable of withstanding these temperatures. Is this a food safe product?
No, it is not a food safe product. It can handle temps up to 250 degrees Fahrenheit, but as we have not tested it at such temps or for the purpose you are intending to use it, we cannot recomment nor warranty it.

What are the temperature limitations or ranges of your aquarium sealant?
We have not tested it past normal tank temperatures so 65-90 degrees would be the accepted range for it.
Date published: 2015-04-28
Is the aquarium sealant heat stable? To what temperature it can be heated? Will it keep the seal at 121 C (250F)?
The sealant should be able to handle that temperature but we have not tested it at that temperature and will not warranty it for this use.

I am wondering if the aquarium sealant is food grade or fda certified?
I want to use this on a water container I use for drinking.
No, it is not.

I'm using the product to seal around a fitting on a filter box. It is not put on very think. Is the 48 hour cure time still required before filling with water.
Yes, please allow 48-72 hours for the silicone to fully cure before adding water or placing into a water-based environment.

Are the formulas identical for the 2.8oz tubes and 1oz tubes?
I am using your silicones to create cages for insects, which involves me continually needing to buy more silicone. Previously I had been using the 2.8fl oz tubes, however, the last shipment I received 1fl oz tubes. I just want to make sure there is no difference between the formulas which may affect my insects differently.
Also, I was wondering if there is a way to order silicones from you directly to avoid this problem in the future.
The silicone is the exact same formula, just in different sizes. Unfortunately, we do not sell this product direct to our consumers at the current time.

More specifically, do the last four digits of the lot number represent the month and year of manufacture; for example, does 0211 at the end of the lot number mean that the tube was manufactured in February 2011? Thank you for your assistance as I do not want to use the tube to do a tank repair if the material is too old.
The 0211 means it was packaged in Feb. 2011. The silicone is warrantied for one year and has a shelf life of 3 years. After 3 years, it could begin curing in the cartridge.

Follow-up to shelf life
Without an expiration date on the tube, is there a way of determining if the product is new or old stock using the lot number?
Yes, the lot number typically tells us when it was manufactured.

What is the silicone aquarium sealant's shelf life?
I don't see any expiration date on a 10.3 oz. cartridge of silicone aquarium sealant. What is the shelf life of the silicone aquarium sealant in an unopened 10.3 oz. cartridge? How about once the nozzle is cut and if the entire cartridge is not used; how long will the rest of the left over material still be usable?
An unopened container has a shelf life of two years. Once opened, the shelf life is shortened, but we don't have any date on it. If you seal the tip well, it should remain good for most of those two years.

Is the top a cap, or is it meant to be cutoff?
Is the top of the nozzle a cap from the 10.3 oz tube? The instructions mention to cut off the nozzle, but don't mention a cap. I want to make sure as I tried to pull it off, but don't want to apply too much pressure and break it.
Just to follow up on my question. The top is a cap as I thought as it spun around when twisted. Not sure if all 10.3 oz tubes have one, but mine did. Sort of difficult to take off, but if you put your nails under the cap and pull it comes of easily. Along the nozzle it also conveniently has cut marks for beads sizes.

Is your aquarium sealant considered food grade?
When installing a drain valve in my honey extracting bucket I made the hole a little too large and it leaks just a little. I was advised that aquarium silicone rubber sealant would work.
No, it is not food grade.

How do I make any non traditional object fish tank safe?
I am making a new saltwater tank in which I will have a bodybuilder theme to my decor. I want take small actual dumbbells and put them in the saltwater to make a fake reef made out of stacked dumbbells. I know I can not just put them in the water. I know I need to properly seal them so them do not leach and effect the water quality in the tank. What would I use to coat the dumbbells with for use? Please help.
There are food grade, fish safe coatings that you can use. We are not able to recommend the actual product, since it is not one of ours, but you might want to contact the show Tanked, since they use the coatings all the time.

How much Aquarium Sealant will I need to seal a 24" x 12.5" x 21"? Also what is the best practice for re-sealing the base and sides?
I want to ensure that I have continuous seal as I transition from around the base to the vertical sides. Can you email additional instructions as the product packaging does not provide much detail beyond preparing the surfaces?
For tanks larger than 10 gallons, there is a double seal at the corners. So there is silicone in between the glass in addition to the smear on the inside corners. The primary seal is between the glass, so if there is a leak through that, redoing the inside smear may not be a long term solution.
If there is no leak, then resealing the interior is mainly cosmetic due to cleaning over time. Follow the packaging for preparing the surfaces. For the amount of silicone, I can only suggest that you look at the amount that was there previously or go to a store and look at some new tanks. If there were about a 3/16” to ¼” diameter bead put in the corners and then smeared that should be enough. Since we put silicone between the glass and smear what squeezes out, the amount for the smear varies a little.
We cannot warranty any re-sealing done by a consumer, of course.

Will this adhere and seal to plexiglass?
I have a 120 gal tank that the bottom broke on, I've reinforced the bottom of the tank, and cut a piece of plexiglass to cover the entire bottom (inside) the tank. The tank is used as a terrarium, and the bottom is broken on the "dry" side. I also want to reattach the angled piece that separates the wet and dry sides, which is plexiglass as well. Well this sealant adhere to the plexiglass?
Silicon generally will not adhere very well to Plexiglas or acrylic.

Will this hold for resealing 90g aquarium?
Recently bought a 90g tank used, I want to clean and reseal all the seams. Will this stuff hold up to the pressures from 90g of water?
Re-sealing an entire tank is extremely difficult, and we do not usually recommend it. That being said, yes, it can be used for this purpose.

will the silicone stick and dry on a plastic bracket?
Hi I'm planning on hanging driftwood roots into my discus tank from the plastic bracket that goes across the middle of the tank. Will the silicone stick to the plastic bracket? How long does it take to dry and cure? Do I add the silicone to the bottom of the root structure and stick to the bracket? Or do I add the silicone to the bracket and attach that way? Also and finally how do I prepare the surfaces to be bonded?
It would definitely stick, but we don't recommend your doing this to the brace. That brace is critical to the support of the tank, and if the weight of the roots eventually causes it to crack, you will need to replace the frame or the entire tank.

What does it adhere to? Will be using it to seal a plug to ceramic tile hole in a fountain. Nylon plug. Will the sealant work with ceramic tile and nylon plug?
Silicone would likely stick well to the ceramic tile. It will not stick well to the nylon plug. If the plug is at the bottom of a fountain under much water depth, it may leak eventually. However, depending on the design, water pressure can help keep something sealed also. If it’s a force fit type tapered plug, it might do ok, because the nature of the plug is to seal under pressure. If it has threads, it may be able to leak through the threads.

my tank has a tiny leak to the top corner & because of this i cant full my aquarium all the way to the top as i had it before, can i use this product to fix the leak without removing the fishes?
If it is a sealant issue, yes. You should just drop the water down, let it dry, and re-seal. Ideally, you are supposed to remove all of the old seal first. Silicon will not attach to old silicon.

Hi Im looking for a glue that can be used under water without emptying the fish tank. My fish tank is a marine tank and it is leaking
I just want to know if the marineland aquarium sealant will work and if not which other glue you recomend
No. We don't know of anyway, whatsoever, that you can seal it without emptying it first. I'm sorry, but you need to find a safe home for the animals. Perhaps your local store can help you out.

How much Marineland Caulk is needed to reseal 90 gallon tank.
I want to be sure to order enough caulk. I will be resealing bottom and sides. Also, if old caulk doesn't stick to new caulk, will the seal be sufficient laying over the seams, which have not been removed. Thx.
I have tried to get an answer as to how much you will need, and have not been able to do so. I have received this though, from the engineer:
It would be ideal to remove as much of the old silicone as possible from the interior of the tank without cutting into the seams between the glass. Razor blades are the best. The window scrapers that can accept razor blades make it a bit safer. Acetone or isopropyl alcohol can be used to wipe down the corners and let dry before applying the new silicone.
An alternative to remove all the silicone could be to just remove any loose silicone or places where it appears algae may have gotten between the silicone and the glass. Then clean the glass and remaining silicone with acetone or alcohol and re-seal. They’d want make sure to get enough silicone in there to fully cover the old silicone.
In addition, this is just general advice and no warranty is implied should any damage result from your re-sealing the tank. You re-seal the tank at your own risk.

can we use it in manufacturing new aquarium process (DIY) or only for repairing the exist one
It can be used for either. Make sure all old silicon is removed first, and the surface is clean and dry, if you are repairing.
