I have a 5 gallon stricky plant grow out tank,
I have mosses, and frogbit along with duckweed. Small sponge filter running, along with a DIY co2 system. 2 WPG
I want my plants to grow fast, I use the PPS Pro method for fert, and I also dose excel once daily, it has been about 2-3 weeks not and nothing has grown at all or at leats noticeable. some of the Frogbit has lost its green color and is turning whiteish yellow
my water I just tested is as follows
Nitrite 0 PPM
Nitrate 160 PPM
I use the water I sphion out of my other tanks and add it to this one.
What am I doing wrong if anything?
