The nitrates are not coming from the tap. I'm pretty sure I was overfeeding. I bought the green fert pack from GLA
◦Plantex CSM + B
•Macros - ◦Potassium Nitrate (KNO3)
◦Mono Potassium Phosphate (KH2PO4)
◦Potassium Sulfate (K2SO4)
I don't know much about the chemistry of all of these yet, but I'm picking it up. None of these are a GH booster right? The GH test is not old, I may take a sample to my LFS just to check against my test.
I have just plain gravel with API root tabs. I already have AS for the next tank, I'm not going to change the other bulb since someone said it wouldn't make that big of a difference.
Thanks for the help! The search feature can make my head spin.
