more flow needed?

[dmh41532]

I have a 20 gallon long with LPS, zoas and some mushrooms. I use a hydor nano 425 gph. I this enough flow for my tank? I notice detritus pockets are starting to build up in one corner of the tank.

You dont need more flow volume you need more water movement and the proper bio mass to eat the ditritus IMHO

How is your clean up crew?

Ever think of adding a powerhead or two to create water movement?

I have a one blue legged hermit crab, two bumble bee snails and two turbo snails. Yes, that's I've thought about adding another one, that's why I started this forum. Any suggestions on size, brand, ect?
