Is it true if I make my own stand it will reduce warranty of the tank?
Asked by: Eric999
Yes, it is. Custom stands have not been properly tested to see if they support the pressure points correctly or not. Therefore, the warranty goes from life time on the tank, with coverage on other items besides the tank, to one year on the tank only. BREX

Recent problems with seam failures

Looking for a larger tank to replace my 200 gal. For the money and warranty I'm attracted to the 300 DD. However, doing some research on a few popular forums, there seems to be some seam failures recently. Any thoughts on what might have been the issue and what has been to resolve it? Thanks
Asked by: Paul1972
We are always striving for continuous quality improvement. We incorporate quality checks at every step of processing. We have added some changes to our large tanks that include the use of clear silicone on the bottom seams so we can more easily see any bubbles or flaws during construction. We have also improved bottom edge cleaning of vertical glass. Marineland stands behind our warranty. MINI

How many drain holes are in each overflow

I am looking at the 125 gallon and was wondering how many drain holes are on each corner overflow. I would like to run the herbie method so I would need two on each corner so one can act as a backup in case the first gets clogged, and then one more for the return on each side.

There is one drain and one return on each end. BREX

tank lids?

I just purchased a 300 gallon deep dimension aquarium. when I received the lids for the tank I found that each section was cut at 22.5 inches wide. the middle section of the tank where the lid sits is indeed 22. 5 inches wide. but the outer ends are 22 3/4 inch wide so the glass lids can slide and fall into the tank? My local fish store tells me that this is the only size lid that is manufactured for the tank? How can I fix this problem? for such an expensive aquarium I would think that the lids would fit properly?
Asked by: thedozerboy
The lids are actually just over 22.5" wide (cut at 22.75 but after they are sanded down, spec is 22 and 17/32 or 18/32 inches. Therefore, once they are situated into the inside framing of the tank, the canopies may shift from right to left, but should not fall into the tank. ML2

Corner Flow Question

I just purchased the Marineland 200 gallon 36x48x27 tank and am slightly confused by the statement found in product description that the flow rate is 700gph, I want to make sure I purchase the correct pumps to accommodate this flow rate but my tank has 2 corner flows, is my recommend flow rate 1400 gph since there are 2 corner flows on this model tank ? or is 700 gph to be assumed that 2 corner flows were already taken into consideration when basing this flow rate ? Basically, i need to know if i need 2 (700 gph) pumps or 2 (350 gph pumps). Thanks for your time to review.
Asked by: oceanreefz
Great question! The ideal flow at the head height of the top of the return from the bottom of the sump should be 700-750gph (ie, at the 4' vertical lift, the flow rate would need to be within this range of gph as each foot of elevation reduces the flow rate by around 100gph.) So for your dual Corner Flo, you would need to take into consideration that you would need this equation doubled with a Y splitter/diverter on a higher powered pump (1400-1500gph at the appropriate height) or 2 (700-750gph) pumps.

No, we do not make a 300 gallon rimless. It is extremely difficult to make rimless tanks. And no, we do not have an in wall option stand. You can do a custom stand, but that will reduce the warranty from lifetime to one year. BREX

Required sump size

What is the required sump size for a 250 dd tank. How much water will drain during a power outage
Asked by: Tonydafish
We would recommend looking for one that can hold up to around 40 gallons. What’s more important is the remainder of empty volume in the sump after you’ve reached the operating level of the sump. During a power outage, you’d lose around 10-20 gallons to the pump, as long as siphon break occurs quickly. You’d want the sump to have that much additional space above and beyond the operating level. BREX

What are the dimensions of the 250 gallon tank

I am building a stand and need to know size of tank andsize of corner cut outs for filtration plumbing
Asked by: Blox58
I have to tell you that by building your own stand, your warranty on the tank will be limited to one year from the original date of purchase and to the tank itself. If it leaks, water damages will not be covered. Custom stands, unless built by those experienced in building them for all types of tanks, will typically cause issues a couple of years after tank set up. 60-1/2 x 36-1/2 x 27-1/4 I will email a diagram to you.
