I plan on doing my conversion to a 20 gallon long for my reef soon. The 29 is just not working and the algae just cant be stopped. Im going to try from scratch with a smaller footprint and a sump.
What a decent size sump to build for a 20 long? I cant go to huge,I was hoping 10 or even a 5 I have lying around would be sufficient.
If thats not worth it then Ill prob just drop reef all together, call it a wash and sell off my stuff.
