| Re: Using skimmer and UV sterilizer the skimmer is very important and will not do enough harm to worry about it. The UV sterilizer is not needed in a reef and will kill any plankton that enters it. i have heard of using one for a couple hours after a water change, but i never have personally. I got one on an impulse as well and it is now rigged up on my pond instead. live rock should choke out any algae as long as you have enough and don't run the lights too long. |
