So I was happy with my tanks circulation (low flow) for the last several months. Other then my diatom bloom and the random pebbles/empty shells my fish leave everywhere, my sand has been very clean so I hadn't worried about increasing flow. (About 2000-2500 GPH depending on my return pump setting for a 150 gallon tank)
I know a lot of people say it needs to be much higher, but my focus was fish and I didn't want to create a turbulent wave pool for them to live in. Despite what people say I distinctly remember diving in Guam and seeing tons of fish in low to no current areas... actually saw less in high current drift dives now that I think about it.
Anyway, now I'm getting red cyano bacteria on the sand, mainly in one area that I believe to be more or less a dead zone (sand particles remain fairly suspended in that area of the tank which is my only real clue). I'm thinking of upping the flow and was wondering what everyone thought about pump options.
1) Are the dual head pumps worth looking at? I was thinking of getting them since I have a custom made lid that only has cord slots for two circ pumps.
2) Any comments on Current USA?
3) Should I do a high flow and aim it away from the sand and oppose it with a lower power (1500 gph vs a 750 5ft away)?
Any suggestions would be appreciated, but I'd really like to hear about the dual head ones if you have any experience with them. Thanks.
