With the 24" high tank, your 4 x 65 watt CF light is putting you in low light, probably very low with the 2 actinic bulbs. If you are having problems with plant growth, you might consider replacing the Actinic bulbs with 6500k - 10000k bulbs. If you are testing your nitrates and phosphates, you can determine whether or not you need to dose them. I would replace the Flourish Trace, with regular Flourish Comprehensive. The Trace has practically nothing in it, and no iron. The Comprehensive will give you all the micro's you need.
Then why are all my low light plants like anubias covered in black beard algae? But yet my high light plants are thriving? and why did i have a huge algae bloom for weeks? im not entirely sure what type of lighting it is. i bought it used, it came with a tank the fixture is gigantic, built in fans, gets decently hot,etc it is an odyssea fixture and its four-bulb, 260watt and 65wpb thats pretty much all i know. the label says actinic blue and 12,000k but who knows it might not be the same stock bulb, the fixture seems pretty old maybe a year. and my high light plants are flourishing, my problem is getting the low-light plants to grow. and i also really want them to grow faster, some are but most are still melting from introduction, most of the plants are fairly recent -2weeks in tank. the old plants are doing fantastic! my vals, pennywort, hornwort, hygrophila, rotala, crypts, lotus, aponogeton are doing great! the pennywort, hornwort, and crypts all have lots of new growth but its just disgusting to look at, algae mess. the echinodorus is split in half, some are thriving, some are a rotting corpse of melting plaster. the lotus has so much growth its amazing. its got 15-20 new leaves from just a bulb in 1 month! the aponogeton went from a bulb to 4-leaves, each 12" high in 1 month too! i am already about to buy the pottassium and phosphate as well as regular flourish-(if thats what comprehensive is?) and im still trying to find plant weights to prevent uprooting. i had no idea trace had no iron? my problem isnt getting them to grow, its getting them to grow FASTER!! i want the type of growth where you wake up in the morning to 20 shoots. i usually find a shoot or two every other day. all advice is appreciated
