svachon9 Posted February 28 Share Posted February 28 90 gallon tank, low tech (no CO2), using Easy Grn and Root Tabs. Moderately planted (Vals, Crypts, 1 Am Sword, Bacopa, ludwigia and java ferns) with heavy fish load. Coop light is on for 8 hrs. Started light on for 6 hr for a month, 2nd month at 7 and now 3rd month at 8 hrs. So, what would you recommend for light intensity? Because of it's a deeper tank (24" deepth-90 gallon), would you go with 80% or higher? Having moderate plant success so far. Link to comment Share on other sites More sharing options...
johnnyxxl Posted February 28 Share Posted February 28 I would step it up slowly like you did the hours and see how the plants do, keep track of nutrients and adjust dosing accordingly also. Link to comment Share on other sites More sharing options...
svachon9 Posted February 28 Author Share Posted February 28 Ok thanks. Just curious if anyone else has a 90 gallon and what they use for light intensity. Link to comment Share on other sites More sharing options...
JoeQ Posted February 29 Share Posted February 29 (edited) I have a 36g bow front which has the same problem. Its deep but not as deep as a 90g. To find appropriate light intensity I used ludwigia as my indicator plant. I planted it at various spots and at various heights , some pretty close to surface level and watched for its reaction to the light. When it opened and closed in tune with my light cycle I was confident I had enough light reaching the surface.
