i completely understand how your feeling. i have tried everything with my cyano
issue and it didnt do a thing. a phosphate test wont say anything because either the algae is eating it all up or it is undetectable, although the test kits we have arent able to measure where we need them. they tell us when things are really bad. If your not using rodi
, use it now. thats the best thing to do. start feeding everyother day or everyday very sparingly. a blackout shouldve taken care of most of it. is this cyano
your dealing with? i had to get the red slime remover for me, but im still doing all of the things im supposed to do. it wasnt growing so i knew once i killed it, it wouldnt start again.
