what size pump for 9V Turbo Twist UV

Why is this info never included in the directions. I have many Maxijet 1200 pumps laying around but want to make sure that this is the rigth size.

thanks

 

Just about any 100-200 gph pump should work fine.
A maxi-jet 600 does ~160 gph, so that would be fine.
The 1200 pushes about 295 gph, so that might be too much.

 

It all depends on what you want to kill. I have a 36 watt turbo. I just looked up the 9 watt ones. For a turbo twist 9 watt UV, to kill:

Parasites: water flow should be a max of 55 gph
algae: water flow should be a max of 121 gph
bacteria: water flow should be a max of 253 gph

My 2 cents would be a flow meter and a control valve to keep things at a good flow. If you want to control things like ICH, then you need a max of 55 gph. Also, remember that UV do NOT mess with your tank cycle. The bacteria that breakdown amonia, nitites and nitrates are not free floating in the water.

 

thanks even better...I have a maxijet 600 on hand also!
