Hey everyone, sorry for being slow to answer but thank you all for your replies.
I was running my bulbs for 10 hours a day, I need to pick up a new timer to get things exactly where they should be as my CO2 was on the same timer, now I've been manually turning the light on an hour or 2 after the Co2 comes on (so probably closer to 8-9 hours a day now). I was hoping for fast growth which is why I had both bulbs in and it seemed to be going well at first but then suddenly the algae went crazy. I use flourish because it's easier to get locally (I'm in Canada, pretty limited here). I too wondered about potassium, I had been dosing based off of "the fertilator" and my potassium fell just slightly short of their target range (kno3 is my only potassium source), but i was originally dosing 1 tsp instead of 1/2, cut it back based off the dosing sticky on this forum. I assumed i'd have problems like holes in plants or yellowing, didn't attribute the potassium to algae issues. As for my HoB Filters, I keep my water level high for minimal splashing, I figured if the drop checkers are turning more yellowish come the end of the lighting period that I can't be losing too much. I'm using an atomic diffuser on my co2 setup. I've tested the water and there's no ammonia or nitrites registering. This tank has only been set up by me for a couple months now, but it was setup for a long while from it's previous owner, was tore down and brought here within about an hour, though i did change out the substrate (which is a mix of gravel and flourite). I'm honestly not sure what all my plants are and i'm not good with the names, but i know i have some java fern, vals, Mayaca Fluviatilis, Hygro. polysperma, some pearl weed, a large sword plant, and a couple others. I realize Java fern and such are low light plants but they seemed to be doing good under high light until suddenly the algae broke out.
