Help with new nano.

[i have crabs]

is it possible to move them to a area with more flow?
i run a aquaclear 50 filter on both my 7g tanks and the flow is good but you cant control where it goes at all

I had 2 powerheads and an AC mini on my 8gallon nano. I used one of the powerheads and pointed it where the AC mini flow came down,and found that together they were quite effective at controlling the flow off the mini

I don't use those powerheads anymore, so yeah, if anyone wants em, make me an offer.
