Im in the middle of battling some thread / hair algae in my tank and Im trying to figure out what a good Iron level is to shoot for. Im using the Hagan test kit and it shows about .25 ppm Iron & 1+ ppm chelated iron (test tops out a 1). I though this was kinda high so I threw some carbon into my filter to try to lower the levels some (not sure how effective this is). So what would be a good iron level to shot for? Im dosing with PPS daily 5ml / 55g.
I know that not the root cause, Im just trying to get everything in balance. Im pretty sure the algae woe's are due to a combination of filtration, poor CO2 concentration on one side of the tank and low PO4 overall. Iv pretty much addressed all of these issues but I just wanted to check on the iron.
