elegy ?????????????????

whats the best way to stop algae sorry in bubbleponic set up ??
there is no light gettin in as far as i no and im dubble checking the togay by painting my res black under cote and wight ova that.

I hope you mean 'algae' or you can ignore my reply. algae absolutely needs light to survive. If it's in your res, it's getting light.

The spray paint that is labeled for plastic doesn't scrape off as fast i have found.

yeah I am guessing that he means algae, lightproofing your rez is a great idea
I would look into using h2o2 in your rez unless using organic nutes
