Building a new sump!
Many of you helped me with converting my sump into a refugium but now my friend is setting up a reef tank!
He's not sure in either a 75 or a 55 but he wants to use a canister filter, I personally don't like those, because they are so high maintenance!
So I talking him into building a sump but I'm not exactly sure how?
What do you all use to keep the dividers in place? Probably going to just buy a standard 10 or 20 gallon tank depending on what size he buys
But my first question is, how to keep the dividers in place? Is it a type of glue? If so, what kind is safe for fish?
