I'm Considering buying this product but I was looking for a media that I could add to my emperor 400 to help combat algae.

Asked by: John W Menshek
Well, this is not a media. Algae is due to nutrients in the tank. The best way to combat it is to vacuum the gravel and do partial water changes. You may want to do small changes a couple of times a week for a bit. Also, make sure your lighting is okay. There are different types of algae, and lighting can cause some of them. If you have a fluorescent fixture, replace the bulbs every 9 months. If it is near a window, block the light from the window. For media, you can either add a second cartridge or fill the media container with bio beads, filter floss, or something similar. Phosphate pads can help too, and can be inserted in front of the filter pad. BREX

Used as directed, and now my discus are darting and crashing into tan walls. Can this product cause neuro issues in fish?

Asked by: Rowtrolljoe
No, but discus are very sensitive fish. This is a chemical that needs oxygen to perform its job, so it may have caused some oxygen issues in the tank, if the level was already low. Or it could just be discus being discus. They are very sensitive to ANY change in the tank. Algae should be controlled by frequent, large water changes for them. BREX

Can I use this on a 2.5 gallon betta tank with one betta and no live plants

Asked by: MeghanD
As long as it has been set up for a minimum of 3 months, and has good filtration, yes. Or you could add a couple of nerite snails and they will consume algae on any of the surfaces. BREX

Would this be safe to put in my horses 92 gallon water trough? Already have goldfish in there but a week after changing water it is green again.

Asked by: vhcambrian
This has not been tested on horses. I would recommend barley straw pillows, instead. This is an all natural method of removing the algae that will not harm them. They come in various sizes and you replace them every 3-6 months I believe. (I have horses). Your water is going green because of the sun and the amount of waste the goldfish are producing. Goldfish do not help with algae, they make it worse. BREX

Hi I recently bought this product nd I wash my tank nd put some of this algae eliminator nd I left home nd came back nd all my fishes were dead ? Do you guys know why ?

Asked by: Mzrachel
Without more information, we cannot say for sure, but most likely it would have to do with washing your tank. Another possibility would be if you did not leave the filter running while the chemical was in the water, or possibly an overdose. BREX

Can this product be used with a Beta? It's a 3.5 gallon tank that is coated in brown algae within a week.

Asked by: steepo
Yes, but if the tank is new, this is semi normal. Make sure your light is only on for about 10 hours a day, and the tank is not near a bright window. Do a partial water change and wipe the algae off with an appropriate algae pad. Feed twice a day, one or two pieces of food and no more. Algae is easily prevented but if you continue to have issues, then try the Algae Eliminator. Make sure you follow the directions carefully. BREX

We would not recommend this for use with the crayfish or upside down fish. As long as the tank is well cared for, the baby mollies should be fine. BREX

Asked by: Friendly
Thank you for your interest in this product. No, you do not turn the filter off at all, leave it running. This will not affect your biological filter unless the tank is way overdue for a water change. BREX

When the directions say to remove the carbon filters for 6 to 8 hours do you still put the filter in with the bio pellets and the cartridge and turn it on?

Asked by: Kim276
You only need to remove the carbon so it does not pull the treatment out of the water. The filter should continue to run as normal, with all other media. BREX

Can I put algae eliminator in tank with my goldfish is it safe?

Asked by: evile
It is safe for goldfish, yes, when dosed properly, etc. It is not safe for live plants, snails, shrimp, scaleless fish, etc. Always do a partial water change first, and remove some of the algae. Let the tank settle down for a couple of hours prior to using the Algae Eliminator. This ensures a good supply of oxygen for utilizing the chemical. BREX

I have a small aquarium tank (5 gallons). What should be the amount of Algae Eliminator I may use? And for how long I should do it?

Asked by: xabielpr
No more than 5 drops. I would do a partial water change, and remove what algae you can. Remove your carbon, leave the filter operating, and have an air stone if possible. Add 5 drops after the tank has settled down from the water change. Put the carbon cartridge back in after about 3-4 hours. Wait 3 days, remove carbon again, and add 5 more drops, but only if it did not get all of the algae the first time around. BREX

How can I get rid of black algae (?) growing on my live plant leaves in com. fresh wtr aqu.

Also, some of the other plants are browning...could it be the water ph? I have lights on all day for plant health, and they were doing very well.....
Asked by: PeggyA
First, this is most likely black beard algae which is common in such tanks. It occurs due to excessive nutrients and either improper lighting or fertilization for plants. So I would recommend vacuuming the gravel and taking out 25% of the water and putting fresh back in with a dechlorinator if necessary. While the water level is low, cut off the leaves that are most affected and remove them. Secondly, what type of lighting do you have on the tank? If it is fluorescent, your bulbs should be changed at least every 9 months. If it is led, make sure it is the right model of led. BREX
