hi,
As the title says i have this algea GDA and i cannot get rid of it, every time i scrape it off it keeps coming back in max 3 days.I've read about this algea alot , and i honestly don't want to use the first method of killing it, i think there is not much annoying thing then to let this yucky thing on the glass for a month or even more until it finishes its full cycle and covers the whole glass so u can't see inside.
I just don't wanna use this method beacuese i 've read about another working method wich is called the MCI ( method of controlled imbalance) apparently giving results in this case too ( saw in other forums) , so i thought i give it a try.
The method says as far as i understood ( please correct me if i'm wrong) to use the No3 protocol wich means the following: get the Fe and Po4 as low as u can possibly to 0 by a large water change, then start to add only KNo3 every day until u get GSA ,( and of couse keeping or CO2 at max) ... at the point GSA appeared on the glass u stop with the KNO3 protocol and start with the Po4 protocol to eliminate it ( gsa) . If i'm getting well when the GSa appears no other algae can flourish or all any other types dies. This is all ok and nice but i still do have a lot of questions.
1. Do i have to add only KNo3 and no other macro nor micro during the protocol,?
2. Won't the plants show deficiencies during the protocol if i dose only No3? ( for example if i used to dose EI there gonna be huge deficiencies IMO)
3. What is the shortest time one can get rid of this algea with this method?
4. GDA is flourishing when there is an inbllance between Ca and Mg perhaps Po4 too ...
Could i solve this algae problem by simply resolving the correct ratio between Ca and Mg like 4:1?
here are some datas of my tank: 300L heavily planted , pressurized co2 with external reactor, 0.7w/L, EI fertilizing, weekly 50 % wc.
I Really expect some useful information on all this ,
thanks.
