My 1st real quality sump and very excited about my purchase. I set up all the plumbing myself. I get a thrill just knowing that I did that and everything works great underneath my tank. I’m happy with the results. Many different water flow configurations with this 4-1 model. The only downside is that Amazon doesn’t sell the media cartridges or accessories that go into this sump. I bought this for my 220 gal plexiglass tank. I had 2 older sumps rigged together waiting for a catastrophic flood to happen. You can see a little rust debris under my steel stand from a previous mess I had made from mistakes in the past. I used a very thick gauge steel when I welded my stand so I’m not too worried about being structurally safe bc it’s solid. I would definitely endorse this equipment to anyone serious enough to get involved in this hobby. My tank is still waiting some new lighting. Also planning on rearranging the sump configuration for housing a refugium with chaeto algae. My fish only tank is well established with beneficial bacteria and copepods in my live rock. I have neglected my tank for a minute but know that all will change for the better soon!
