Hello everyone! My wife and I have a 55 gallon aquarium that we started down the salty road with about 5 months ago. We dont have a lot of stuff in it and have been aquiaring equipment and things slowly. The tank was given to us and a stand with it too. We wanted to do a sump under it and had some fun times trying to find something to fit under a stand for a 55 gallon aquarium. We ended up using 2 10 gallon Rubbermaid totes connected together with a pipe and union. It works but not ideal. So we have been planning for future upgrades and expansions and because of that I have built a new stand that will hold a 75 gallon aquarium and allow for a 40G breeder under it for a sump. Yay! So our plan is to put the 55 gallon tank on the new stand and hook it up to the new sump-to-be, until we can afford a new tank to go with our sump. (Poor preacher here) So we are moving really slowly and we like it that way, but I have been trying to figure out how to layout the sump. I was able to get a nice deal for a protein skimmer on Black Friday and also used some pal rewards and 50% off for a 40G breeder tank from petco for the new sump. Wanting to keep it simple for now we were going to make the sump like the pictures below. In the “refugium” section I was going to put some live rock that the wife doesn’t like in the Display tank and a ball of Cheato. So my question is will the flow that I have drawn out work ok? We don’t plan on having any sand or critters in the refugium. I sure love this forum. I really can’t believe how nice everyone is and helpful. I also appreciate that I don’t have to worry about if kids are looking over my shoulder because it’s clean. So I do want to give a big thank you to everyone for making this an amazing community.
