I am going to adopt a 4-inch bushy-nose pleco from a friend and give him a private residence in a spare 20 gallon hex aquarium. He'll be all alone with 3 nice big blocks of driftwood. I hear plecos like a lot of water movement, but I was curious how much is "a lot". The current filter is an AC70 with the intake 5-inches off the bottom, ......so 300 gph, but its a 24-inch tall hex, so the bottom water isn't moving too much. The two powerheads I have are a 170gph and a 340 gph. Which do you think is more appropriate?
thx
