    I am not sure what is causing this. I was wondering If I should scrub it off ?

    This is 1 day after a 50% water change .

    That's certainly a lot of algae growth for 1 day. My immediate thoughts are that your phosphate levels look high and nitrates a tad low.

    Your plants do look a bit stunted to me. What I would do is scrape of the algae and give the gravel a good clean ( there does appear to be a lot of gunge there) and then do another 50% change without the KH2PO4, add K2SO4 instead.

    CO2 seems off to me for that to happen. Nutrients shouldn't be of any issues except lowering the PO4 dosage to 1/16 teaspoon per dose. What is your CO2 level 1 hr into the lighting period and end of the period? Oh, do get more plants in there...that is skimpy planting as Tom calls it. :D
