I'd get a drop checker with a calibrated 4 dkh solution to get a better handle on your CO2 levels. There are too many other variables that can affect pH levels besides just CO2.
When you list out all the things you've tried- how long did you try them all? It can very easily take weeks to months to get algae outbreaks under control. You need to take things slowly, change only one thing at a time, and thereby eliminate possibilities one by one.
TY for the info. I try to give it close to a week, not to complete remove the algae, but just to see if its still exploding. I know I would need much more time to stabilize, but its my impression that I shouldnt see excessive growth during that week. Pretty convinced its Spyro (yes the pics do show some left over diatoms, but thats not my major issue). And i shut off the Ray IIs, now just on the planted+ for 7hrs. also upped my CO2 last night.
Will also get a drop checker
