I have a 150DD with a minimalist rocks scape and a decent amount of sand in the tank (about 1.5 to 2 inches deep)……I have been using 2 gyres (the smaller model), but I would like more flow control to deal with some dead spots in the tank…..I have to keep the flow at the bottom of the tank low so that I don't create mounds of sand with bare spots in the tank, that said I feel like I am blasting the top of my tank, but the middle is not getting enough flow. I would also like more variable flow regimes. I only want pumps on the back of the tank to keep the minimalist feel to the equipment in the tank.
I have been thinking about going with several small power heads to have greater control of flow, but I can't' find good reviews on small variable pumps. I can't use MP 10s as my glass is too thick and the vortech line only allows me to shoot flow forward. I could dial down my gyres and add some small flow pumps, but they need to be quiet as the tank is in my living room (my current setup is very quiet).
Any ideas / thoughts would be greatly appreciated…..
thanks,
Darren
