Treating the tank with chemicals is..... well..... NOT GOING TO FIX IT!
Peroxide? wow.
You are not going to treat the symptoms and in turn eliminate the problem, period!
Chriskid and I had a LENGTHY discussion, as well as Justin Credible when he and I spoke at Cmac last year. You can't fix the problem if you treat the symptoms.. Why do you think they came BACK!>? because the problem is there. DINO is ALGAE>? Then get your phosphates and Nitrates down, and I KNOW that SOMEONE will chime in against this but hey,m not EVERYONE has the same "opinion"
But Algae LIVE of organics, Chaeto does too, so I eliminated my Phosphates slowly and MY Problem is almost ALL GONE. and I don;t treat my tank with Chems to do it. neither shold you, fix the problem, don't TREAT the symptoms and you will do well.
And if GFO Reactors and Phosban are considered "Chems" then I stand corrected, LOL, Oh and Chemipure really doesn't do enough for phos, but it certainly does HELP,.
That was my Two cents based totally on experience and talking with people., but NOT TOO MANY PEOPLE! No offense at all, but the more people you talk to the more IDEAS you will have to try. The bottom line here is "FIX THE CAUSE NOT THE SYMPTOMS" Period. And nine times out of ten PHOSPHATES are the Cause, and they really are difficult to READ on any test kit OTHER than an electric Hanna, which is the most reliable, and REMEMBER that even when you read close to zero, that is not taking into consideration all the phosphates that ARE in the water column in suspension by the algae that need it. it CANT BE ZERO if you have ALGAE growing...
This is all stuff that Chris and Justin and I talked about. so don;t shoot me down becasue you do not agree, EVERYONE KNOWS THEM so.....
Good luck!!! YOU CAN DO IT!!!!!
