Re: Maracyn/gda experiment...

Thanks for the help in the translation. This makes a lot of sense to me all the sudden. I have very hard water and was dosing Po4 in excess to get rid of Green Spot Algae. All the sudden, I am hit with Red Algae and major Green Dust Algae. I have now done a 50% water change and am going to try to implement "Method of Controlled Imbalance."

Re: Method of controlled imbalances and gda...

Ok, after the 7th day water change, what did you do?

The main idea is to change the way you were fertilizing in order to find a balance in long terms.

GDA is related to an imbalance of Ca:Mg and Po4.

There are two ways to deal with the Ca imbalance.
1) You should reduce the dozing of Ca.
2) Or you should add more Mg.

As I wrote, I think that a better ratio es 4 parts Mg 1 part of Ca.

Regards
Ahh, I got the Mg and Ca backwards. I put 4 parts Ca and 1 part Mg. I used the fertilator, but it doesn't help if you use the wrong ratio, huh? Okay. I'll try again.

Re: Method of controlled imbalances and gda...

However, I have really hard water to begin with and like bosmahe1 do not know the ratio I am starting with before adding the Ca and Mg. Will this make a difference?
