I sometimes wonder if the RDP light cycle is all its cracked up to be. I never see any difference running my scrubber lights on RDP, which I do however. I do try to get my reactor effluent to drip as close to the scrubber feed pump as possible. As mentioned, nothing removes excess co2 like algae. Could one not run the effluent through a refugium first?

Also, I have decided to leave my co2 reactor running and just waiting on another Maxi Jet ph to arrive, to start my kalk reactor up as well.

I can't say Doug that one may notice a diffrence with regards to the amount of algae but I find if I don't run my refugium on reverse light I get a larger ph swing at night. My refugium is lit by a 175w halide though. so it's got some pretty intense light at night.

Come on Des You can stuff one more timer in behind that tank!
