My tank is a freshwater set up with an AquaClear 110 filter and I have dwarf gouramis, full sized gouramis, ctenopomas (leaf fish), mollies, and dwarf suckermouth catfish. I purchased a 60-90 gallon stand from petsmart (online only style) and it's worked well.
The acrylic is beautiful, crystal clear, with perfect seams and rounded front edges. I did not use or install the hood or light that came with this, I had already bought a slim profile adjustable bracket multi-setting LED light and leave the top mostly open. I lose a lot to evaporation but I don't mind putting about 4 gallons of fresh treated water in every 10-14 days. I do 50% water changes with a gravel vacuum(Python with 20" tube) I bought on amazon once every month or 2. After the first 6 weeks my water has remained stable and as near perfect as I can get it with tap water that is pH 8.6 and high in nitrates (I used Seachem Prime and pH 7.5 products on tap water before it goes in, both also from amazon) I use the API full water testing kit weekly to bi-weekly.
I was able to fit some very large decor in through the two main openings. It was tricky, but because the pieces weren't solid rectangles, I got things in somehow that are actually larger than the openings (see pics).
I only use paper towels to clean the inside or outside of the tank. They work well for algae. I have no scratches anywhere on the tank 1.5 years in to ownership.
My heater fit right through the heater opening (first had a Zacro 300W, switched to a Aqueon 150W). My thermometer was a smidge too big for the thermometer hole which is slightly annoying since the cord is more visible but I'm dealing with it. I have the tools to enlarge the hole but I've never gotten around to doing so. My filter is enormous and there's still plenty of room on both sides for the filter opening.
Having a fixed top is annoying for netting/catching fish and gravel vacuuming, but I've learned to adapt and I've never not been able to accomplish what I need.
This tank has been an absolute joy to own and enjoy. I will continue to get acrylic tanks and hope to eventually get some larger/taller versions one day and start a discus tank.
This tank was incredibly light, well made, and I've had no bowing, scratches, discoloration, or any issues.
