Hey guys, thanks again for your previous help, it now looks like grey beard algea is becoming a problem (i don't mind the cladophora, looks kinda cool!)
i've been dosing PPS-Pro daily (using this guide suggested by Rivercats
Newbie Guide to PPS-Pro - PPS Analysis and Feedback - Aquatic Plant Central) and Excel as directed on the bottle, i've reduced lights to 50% on the high light Build My LED dimmer and put a 2 hour pause in lighting mid-day, total photoperiod is 6-7 hours.
Updated tank stats are below, am I going to have to make the jump to compressed CO2? I'd really like to get a carpet going, but every time i turn the lights back up to 75% the grey beard gets worse, tank has been established for about 5 months now, any feedback/suggestions appreciated, i attached some pics, it's taking over the moss, plants and tank glass, note the algea balls on the right side of the wood... thanks!
