Looks like UV is clearing up the water?View attachment 198625
Clearing up… but still not getting that fast fast growth I was hoping for? Any clue What I can do @JoshP12 ? Planning on doing a WC soon.
In terms of growth rate, I think you are inert substrate and only water column. You have max light and high temp.
I think the only way is with more ferts (or co2).
Ca/Mg is probably fine - same with micros. Probably just a bit more N and P and K and go from there.
Since I think you follow K<N.
