Hello, just joined and I'm pretty new to the hobby. I have a 35 gallon hex that I have started as a reef tank and could use a little help with. I currently have a devils hand and a hollywood stunner in there and a few fish. I;m using a ehiem 250 canister right now but might think about trying my hands at a home made sump. I seen a video on here where a guy made one out of a ten gallon and I believe we have the same tanks. Any and all suggestions are welcome. Thank you in advance.
