Hello All, I'm battling some red cyano and have tried multiple natural fixes for root cause with no luck. Yesterday I dosed with chemiclean, removed carbon, and turned off my skimmer. I know the directions say to do the 25% water change 48 hours after dosing, but could I wait longer, like 4 days after dosing? Would this cause issues with the dead bacteria floating around my tank? Reason asking is that I'm traveling for work this week leaving tomorrow. I could go ahead and change my water tomorrow, which would be very close to 48 hours, or I could wait until I return on Friday. Please advise.
