Thanks Oliver,

I will start Carbon filtering the water I use to replace this stuff.


I tested water again today,

Ph 7
Ammonia fell to 4 ppm
Nitrites .25 ppm
Nitrates 80 ppm

Looks like the DO is helping bring this into balance. I also ordered 4' of the air tube to add to the grow bed. Got the light up last night and put a couple seeds in here of some greens to use this free nitrate.... haha.
