Aquarium Advice Activist
I've been reading on these things, and just read the article on this site, which was very helpful, but I still have a few questions. If you have a sump, then all of your filtration/heating will be connected to the sump instead of the aquarium right? Also, in many LFS I see their massive sump system and water being dumped onto sponges and such. There doesnt seem to be very many electrical filters running. What is neccessary for a good sump?
