  • Everything you need
Size: 20Gallon Long
This kit contains everything you need and fit perfectly. I purchased the 20 long aqueon tank and this conversion kit. Everything you need to create the sump is included. High quality material used with appropriate thickness to last indefinitely. As mention in previous reviews, take your time and plan everything out based on your needs. Get it all taped in as the directions show. Mark where everything goes on the outside of the tank and then start from right to left and silicone the first piece in. I used a silicone that sets in 15 minutes and cures within 24 hours. Let the first piece set before moving on to the next piece. This is most important for the overflow and bubble trap on the right side of the sump. Because these two pieces are so close, you need to let this one setup so if you bump it accidentally while putting silicone on the next piece, it will not move and ruin your seal. Great product, I would only change one thing. The support that hold the filter socks are a little clumsy. Nylon nuts and nylon all thread would have made for a more secure option. But this way works, just need to be careful when changing out socks. You could put a small bead of silicone on it to keep it more secure. By the way, get the 4 inch filter sock that is 9 or 9.5 inches long. That works perfectly for this setup. ... show more

  • Get a plan together first once you put silicone on it’ll be easier to work with take measurements
Size: 20Gallon Long
The media could not be loaded. Little bit of a pain in the butt at first but the silicone I used setup super fast so basically the first baffle I siliconed didn’t turn out as good as my next two so work quick also I would start with the baffle furthest away from the filter sock holder and I used my finger instead of the tools sent with the baffles but it’s definitely worth it unless u want to pay 300-400 bucks for a sump I built this sump for $105 bucks I bought a 20 gallon long from petco it was 50% off so the 20g was 25 bucks bought two tube of silicone but one is enough so it cost $100 if you take off the other tube of silicone ... show more

  • Good quality, slightly irritating design flaw
Size: 20Gallon Long
Been using this about a year now everything‘s been pretty sturdy and I’ve used a lot of different equipment and being able to play around with adjustable wall heights was handy, the one thing that I would change is that the panels that hold the sock filter and let the drain through can detach a little too easily I think it would be better if they snapped on or something like that so it’s not constantly falling down while you’re trying to change out the sock filter, they’re low-key a pain in the ass to get back on especially if you’re working in a cramped space which I assume a lot of people’s sump set ups are ... show more

  • Doesn't Fit 20 gallon long like it's supposed to
Size: 20Gallon Long
Does not fit a 20-gallon long tank I bought from Petco. Each piece is about 1/8" too long and will not fit inside the tank. I am trying to contact the seller to see what can be done about that but can't figure out how to contact them. If all fails, I will try to cut each piece with a chop saw but the point of buying this kit was to make life easier. This is a pain in my butt now. ... show more

  • 40b Great baffles for sump
Size: 40B
I have ordered these twice now and have been very pleased. Thickness of the acrylic is good and strong. Pieces cut well. Only thing I would change is the sock holder piece that goes from bottom to the “heightened baffle” would be rounded where it touches the tanks silicone. Other then that highly pleased with the quality of the baffles and will order again if I need another sump setup! ... show more

  • Doesn’t fit.
Size: 40B
Great quality, no directions, doesn’t fit my 40g breeder. I’m gonna have to cut the tank’s rim to get it to fit.
