Advice for flooding after DSM?
I'm thinking about flooding my dsm tank really soon. I've been growing monte carlo and DHG for about 6 weeks now and I think I'm ready to take the plunge. Is there any best way to go about flooding? Should I fill the tank and then drain it once or twice to get any mold spores/algae/detritus out of the substrate? Should I continue to do 50% water changes everyday, and how long should I do this for? What are the benefits to constant water changes during this period, and will it affect my [unfinished] cycle in any way?
I've kept my lights on for 12 hrs/day during the dsm, and I don't know how much I can reduce the photoperiod without harming the plants? Also very worried about melting as I won't be providing CO2 other than some excel for extra carbon. Are there any ways to increase CO2 from the air during the transition, perhaps through extra aeration? Are there any other ways to avoid mass melting?
Also, I see a bit of greenness on one of my rocks, which I assume is some algae growth where the water pooled in one of the crevices or something. Is it best to treat it before filling, or should I wait to fill and then scrub it off before draining the water? What's the best method to avoid an algae bloom?
Hope someone out there can help. Thanks!
