    I've been working on this problem for over a year. I have a 36" Tall 30 gallon aquarium. One Kessill 160W light that's on 7 hours per day. The new broad leaves start off clean and then over weeks dots and slime appears. The 8" thin grass like plants have no problem. I've learned the hard way that this is a low light environment.

    The growth of the plants seem to indicate a good balance of NPK. I use 50:50 hard water:RO. The tetras, otos and amano shrimp are happy.

    Many years ago I added erythromycin and that solved the problem but now i have shrimp and otos which might not like it. Any suggestions? DSCN1609 slime.jpg

    Isn´t a 160 W light too much for your tank?

    Can you post some pics of your tank and maybe provide some info on the species of plants effected.

    Those LEDs look nice, but are you running CO2? I run 17 watts on my little 20g, granted this isn’t a measurement of PAR. Easy experiment, turn the Kessil down to 30% for a few weeks and see what happens. The plant is not healthy right now.
