I purchased a new UV sterilizer for my 125 to control algae and parasites. The type of UV sterilizer is the Double Helix 9 watt system and is rated for up to 150 gal tanks. When I bought the kit I purchased the Aquaclear 201 power head. The power head was too weak to pump the water through it because the sterilizer is mounted under the tank, inside the stand and there is quite a bit of tubing. So I purchased a big 802 and now water is flowing through and it
My question is, when I used the recommended powerhead flow 201 @ 125gph (vs the 802 at 400gph), the powerhead could not push all the air out of the system or maintain any type of water flow. There was absolutely no flow through the uv system.
Now with the bigger one I know that water is flowing, but I don't know how fast. I find the ratings on most powerheads to be overrated/false. But the 802 is rated at 400gph and the uv unit states the rate should be between 100-200gph. Have I over done it? Or is there a way to slow the 802 down?
I am tempted to return the 802 because it is too big, but even this big power head took a while to take all the air our of system. So I have my doubts.
Thanks for the advice.
