two powerheads?

I have a 15g high and I have one powerhead in it. Would two be too many? I have mine lower in the tank so the water will move through the rocks and caves, but the water on the top of the tanks doesn't have much movement.

 

what are you keeping in your tank?

 

it can be because the extra wattage can add a couple degrees but I think with one powerhead you should be fine right? But depends what you have in your tank.

 

I have pulsating xenia, frogspawn, cocoworm, fanworm, GSP (on the ground), Hairy mushrroms, toadstool, and some zoos. Fish I have a dotty back and a pair of false clowns.

 

Hi Rogerstammy - what is the GPH or LPH rating of the power head you have at present?

If you got a relatively small PH and mounted it high and angled at the surface it would give you the surface movement you are looking for - without creating the turbulence you may want to avoid

To be honest I do not know what the GPH or LPH is on my power head. I bought the smallest one. Let me search on google and see if I can get you that info.

 

It is a hydor 265GPH

 

go for around 50x tank size to get a good gph rate.

50x15g=750gph, that is the total flow of all your pumps should add up too.
i recommend koralia because of there broad flow

 

Exactly what I was going to say. K+ and +1

 

Hi Rogerstammy, thanks for the PH GPH info - based on the info above - no problem at all adding another

+1 on the comments above by Sostoudt and PharmrJohn
IMO- In a 15g tall tank as its relatively narrrow,hence more defelction and opportunity to create turbulence ( flow bouncing of tank walls and meeting more flow coming from same PH) coupled with the species you list, x 40 would also be a reasonable target
