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. |
