i've done almost everything, i'm still lost
my plants seem to die off on the bottom, and some of the leafs are bent... showing deformity. Those red spot algae is still developing. I'm cranking up my Co2 as high as possible, according to the kh/co2 chart it is 22ppm. My tank is a 50 gallon tank with a 96 power compact and a triple tube with only two 25 bulbs installed. The water sprite turns yellow but the new leafs are green. Some foreground plants seems to have their growth stunned (calcium?) and some plants have tiny holes (maybe snails). My Anacharis (Egeria densa) grows nicely on the top and 3 inches down the needle leafs are short or dying. I'm confused, i've done so much to trouble shoot problems... and my water seem to be ideal....
my water parameters is as follows:
kH: 3 dkH
gH: 6
pH 6.6
nitrate: 20ppm
phosphate: 1.5ppm
the only parameter that changes is my pH. It goes to 7.2 in the morning because i down the Co2 low at night. the plants don't seem to be intaking much nitrate or phosphate.
