Hello hope everyone is well,

I have a little bit of a problem with GSA and its slowly growing more and more on my slow growing plants and killing off the older/large established leaves. I’ve been dosing Seachem phosphates as I read it helps defeat GSA but it hasn’t really done anything.

I dose iron, potassium, flourish and phosphates into my aquarium which is 13 gallons been established for 2 years with currently a Betta, 8 neons and a Nerite snail.

I dose the following:
Potassium: 2ml twice a week
Iron:1.5 ml once a week
Flourish: 1.75 ml a week
Phosphates: 2ml once a week


tank readings are:
phosphate: 2.0 mg/l
Ammonia 0
Nitrite
Nitrate 20 mg/l
Ph7

can give other readings as well and I’ll add some pictures of the algae problem, thanks to anyone who can help!

I’ll suggest trying apI co2 booster. It helps. How often do you change the water and how much.

I do water changes of about 5-6 gallons a week and gravel vacuum as well so it should be enough? I’ve got seachem excel would that be ok to use?

Yes excell is almost the same stuff but it will kill moss balls and hurts anacharis, hornwort and other mosses.
