memorywrangler Posted May 16 Share Posted May 16 What's the best method to figure out the lighting level/photo period for my new, deep, planted tank? I've just set up this 30g high. It's 24x24x12. It's low tech (ferts but not CO2). It has one of the new coop lights. The substrate has some flourite black in pouches, but mostly it's aquarium gravel capped with black diamond sand. Lots of root tabs. It's planted with Corkscrew and jungle val Dwarf saggitaria java ferns pearl weed hornwort Anubias nana petite One Crypt A narwhal and a Disney queen. The last tank I set up promptly became an algae farm, because the light was too high. It's taken a long time to get back under control. I would very much like to avoid that happening again. So, my questions are: What's the best method to figure out the lighting level/photo period? Should I start low and turn it up if no algae appears? Start high and turn it down until algae stops growing? Any guess about what a good starting point for 'high' and 'low' would be for a tank this deep? Thanks. 2 Link to comment Share on other sites More sharing options...
