My latest CRS only set up uses ADA.
I allowed it to mature for 5wks before adding livestock.
I run at PH 6.5. TDS 130. GH 5. Temp 21.5..
Tank has plenty of Leaves, bark, cones, and a banana leaf, and the shrimps relish them.
About every 4 days i feed a very small amount of Biomax.. Mainly to bring shrimps to the front for viewing, and a head count.
From a personal point, never been happy with CO2, in a shrimp only set up, when trying to raise young. I know others use it without problems.
I just feed my numerous moss on Tropica weekly.
Incidentally, always done weekly 20% water change, prepared to the Tank parameters.
Together with floating plants, Im convinced this helps me run with a very low Nitrate.
