Rated 1 out of 5 by from Made me sick I loved mine for the first two years. One day I come home and there was 120 gallons of water on the floor and my fish were dead. Apparently the bottom seal will spontaneously give out and empty your tank in an 8 hour period

Rated 3 out of 5 by from Bad silicone job I purchased a 220 gallon with built in over flows. Set the tank up for freshwater Discus Fish. This tank is a brute very, very, very heavy once you set it up you definitely don't want to handle it again. After set up and filled with water I noticed a small bubble in the black silicone on the front left seam about in the middle of this seam. I didn't think it was a serious issue, all of the silicone on that seam looked good and the bubble was very small, all other seams were good. due to the weight of this tank, all plumbing and set up complete I really didn't want to move this beast. Two years into this setup my wife called me and said the aquarium was leaking at the seam. By the time I got home there was stream of water shooting out from the seam about the size of a pencil lead. Thank goodness she was home and put a bucket under the stream of water. I went into panic mode, got out my 20 prized Discus and a few other fish put them into large coolers and completely drained the aquarium and took off to my local aquarium store. By the time I had drained the aquarium the seam had opened up abut three inches. I have not contacted Mairneland yet but I doubt I will ever set up another large aquarium again regardless of the outcome. Thankfully I have a neighbor who is in the racing business and he had a crew of strong young men who got the aquarium out of my home for me. I am 68 years old, and there was no way I was going to move this thing with some serious help. I have had aquariums since I was 6 or 8 years old and was my first and only tank failure. MY ADVICE IF YOU ARE GETTING A LATGE AQUARIUM AND THE SEAMS ARE NOT PERFECT IN EVERY WAY DO NOT ACCEPT IT!!!!!!!!!!

Rated 5 out of 5 by from Great customer service I bought a 150 gallon with overflows. The store new everything about the tank so that was helpful. I had a small problem with the tank and wrote a review about it. Marine land contacted me and offered to,,, then did take care of my problem. I've since moved to a smaller home but have 3 marine land tanks. Two 75 gallons and a 30 I made into a dump. I will only buy marine land tanks. Except the horse trough that's part of my sump but even then for a few extra dollars I could've bought another 75 gallon that would take less space in my closet.

I am making a stand for a 48" x 24" tank that I purchased and wanted to make sure for the base of the stand that it didnt need any special support areas? Is a flat surface with plenty of support all that is needed?

Asked by: mikeee
No, we actually do quite a bit of testing of our stands to ensure they support the pressure points of an aquarium. A flat surface is not all that you need, in most cases. BREX

hello, i have an older 150 gallon 72"x18"x27" long tank. the single center brace is pulling off the front of the frame and the tank is starting to bow. Do you have a part number for a new frame in oak.Thanks

Asked by: Eli Smoke
We do not sell frames separately, unfortunately. Replacing a frame puts too much stress on the silicone. BREX

Wanting to replace my marineland 120 with corner overflows, but search says no location found for a retailer. My zip is 45069, I'm just north of Cincinnati Ohio , how far do I have to go to find one please?

Asked by: Reefin for life
That's odd, we found several stores within a 25 mile radius through the Store Locator. http://www.marineland.com/Buying-Options/Store-Locator.aspx Just enter your zip code. There was one store within 15 miles, plus some chains. BREX

I want to setup a bare bottom 180 gallon. I want to paint the bottom of the tank black, but the support braces are in the way. Is the anyway to get underneath then to have a full black bottom?

Asked by: Jern
Thank you for asking, Jern! You should definitely not try to move or remove the braces to paint the bottom of the tank. You will need to work around them. We hope you find this helpful. For more help call Marineland at 1-800-526-0650.

I just bought a 110 corner-flo used and was wondering if you had a owners manuel that could get to help me set up the tank. I also would like to know if one your canister filters would work with the corner flow?

Asked by: PAPAFSH
Yes, canisters work with over flows. We do not have an owner's manual, per se, but can email you the corner flow instructions if that would help. Call 1-800-322-1266 or email techsupport.marineland@spectrumbrands.com. BREX
