No, it means that the form of carbon that Excell is adding when you add it to your tank is different form CO2.

Thanks Bud I read that before I posed, though it seemed conflicting to me since it said it also allows the plants to utilize different things besides carbon plus their forum talks about another process...Ill just ask them directly.

I had a bad problem with cladophora, and fixed my ferts and dropped lighting down, but in it's place this black octopus like hair algae showed up so I tried some excel. It works great, the places I target turn purple and die back daily. What I'm wondering is if anyone has a clue what concentration 3x normal dose is delievering? I once found an epa or dept of agriculture chemical analysis on flourish, but I haven't found one on excel. My guess is 0.5ppm but because I have limited tanks and sensitive shrimp, I don't want to overshoot it.

I want to get a bottle of PDcare or something similar and add it to my fertilizer regemin. If all else fails I"ll just have someone order me the chemical with the CAS#, the chemical is scary because it's already shown that at seachems conc. my skin is sensitive. Usually my tanks cycle through algae constantly because I"m busy, but this is a nice tool until I can set up peristaltic auto-dosers for ferts and water changes. Any and all help appreciated in finding the concentration or a domestic source.

Do you know if excel works also with GSA?

John P.

No, your best best for GSA is raising your dosage of phosphate. Over a week or two, you'll notice it not forming.

Thanks a lot! Now my po4 are about at 1 and NO3 at 15.
Tomorrow I'll try to bring my po4 at 2, I have to increment also NO3?

John P.

Bump the phosphate up to about 3. You can leave the nitrate where it is.

It might take 2 weeks, but your GSA should go away.
