Sat looks fine for me
I've decided I'm going to switch over to sand, and jst pick out and keep a few shells from my former substrate for new hermit homes, etc.
I have now the output from a fluval 305, and 405 canister filter, and from a 400 gph pump thats running my sump, plus two power sweep power heads for circulation at the moment.
Just how stong should my circulation be? Whats a good gauge.... Due to limited space and the tendancy for powerheads to suck up sand and umm limited space I'm about to pull my super sponge filters to make room to add more power heads. What does any one think about cheap and effective wave making strips?
