Im posting a pic of my tank. This is a 75 gallon community tank. In it is 3 angels, 11 candy cane tetras, 8 black striped tetras, 2 sunset gouramis, 1 blue dwarf gouramis, 4 bolivian rams, and 2 platys. This tank is well established and has been running over a year. I am having issues with nitrates. They stay between 20-40 with api liquid test. The rest of the params are this ( all liquid api)
Ph 7.4 ( stable)
Gh 4
Amm 0
Nitrite 0
Dkh 7
My fish are healthy and my tall plants have been growing well. I replaced my t10 fixture with an marineland led about 2 weeks ago and they exploded. But i noticed dark spots and my short plants have been browning since ive had them in the tank about 6 months ago. They are alive but not triving. I added another marineland led fixture just now. I feel like the tank is well planted ( i wouldnt say dense, but well). I have been doin 20 gallon pwc every week to try to keep them low. Ive Never seen the nitrates over 40 no matter how long i go btwn changes but i cant figure out why the plants arent consuming them. I quit dosing ferts about 2 months ago. Any suggestions?
