flow recommendations

[lowsingle]

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

The way the gyres are suppose to work is by creating a "gyre" in the tank, so the bottom should be getting a proportionate amount of flow as the top. Are you saying that even at 100%, there's not enough flow at the bottom or that you can't turn it up to 100% without stirring up the sand?

I would suggest some controllable tunze.. like the 6055 or 6095... lots of flow, controllable and can be aimed easily... also fairly small so they can be hidden well

I can't turn the flow too high as I will blast the sand everywhere. My big problem is dead spots....gyre effect works great in an empty tank, but with my rockscape I get lots of dead spots.

 

Does tunze make nano sized pumps that are variable?

 

Thanks for the ideas,

They do make nano size variable pumps... but you can go with a couple mid size pumps imo
