Sorry for the poor quality tank photo, for some reason Im making this post mid-gravel vac. I can’t seem to get anything to grow besides algae and java ferns. My tank is a 34gal rimless cube and my lighting is chihiro WRGB2 slim. I’ve been trying to find out exactly what settings to do for my chihiro but the light spectrum percentages and the % and K value are very confusing to me as a first time buyer of this light.

I also have a co2 system but recently turned it off due to reading that can cause algae if my plants aren’t doing well. I’m interested in growing corkscrew vals mostly but the 3 I have are either not growing (2) or are growing very slowly and short (1).

Any help is very appreciated!
