Killed green water with Hydrogen Peroxide

[kwc1974]

like it says, had a tank that looked like pea spu. Pulled some plants and released a load of nutrients into the water column. Did Black out and water changes with no luck. was about to buy UV for this tank when I decided to try hydrogen peroxide Been using it on cynotbacteria, staghorn and BBA with a lot of luck, so why not green water.

Here is what I did
-50% wc
-2-3mil per gallon twice a day for a week. pour directly into tank.
-50% wc

water turned crystal clear.

sweet man, i heard of this before but have never tried it

[kwc1974]

It was really too cheap not to try. I will be keeping a bottle in my stand now all of the time.

Wow. That's awesome! You say you treated for a week and then did another 50% WC? Or did 50% WCs daily?

Did you notice any problems with the fish?

[kwc1974]

Water changes were done one week apart from each other, H2O2 was dosed daily. No problems with any of the fish or shrimp. None of hte plants had any problems either and I have a couple of "sensitive" plants in there as well.

Did you notice any dramatic change in pH?

Did you notice any dramatic change in pH?

same thoughts here. but 2-3 ml isn't really that much H2O2.

[kwc1974]

No change in pH, but then I was not checking every day. I do not think it would have had much effect except to lower it a little. The only 24/7 indication of pH I have (and I know this is not directly monitoring my pH) is a drop check for my CO2 levels and I noticed no change in the CO2 levels during the dosing period of my tank (I figure that if the pH had changed in a very noticible way then my CO2 levels would have changed too).
