[diablo]

im battling cyano it is in my refuge :scared: as well i have started the first step of cutting back the lights to 7 hours. now my question is if i turn off my lights on the refuge will it have negative affects or will it not matter.

if you has use chem clean let me know. :thinking:
i know it clean kills benificial bacteria but if i use cycle after the water change will the help in my war on slime

If you turn off the lights in your fuge your plants will grow and need to be pruned. That's the negative effect. As far as the cyano you can use chemi clean, then use "cycle" and in a few months you may hafta repeat the process. Chemiclean is band aid. The stuff prolly works, but what works better is finding out why you have cyano to begin with and taking the proper steps to remove it. This may help...
