Flow in a 5gallon?
The 5gallon I have cycling got hit pretty hard with BGA a week ago and I've been reading about low flow promoting algae growth. I want it to be a shrimp tank and I've read that shrimp don't like too much flow so I'm curious, do I really need a current in the lower levels of the tank to fight algae or no, and if so, how would I provide it to a small tank? I have a small cascade HOB filter with a piece of sponge beneath the outflow to prevent it from knocking around plants and substrates, but it's mostly for surface agitation.
PS: H202 is AMAZING at fighting BGA!
