Thank you! The hairgrass has really grown, and I'm about 2 weeks into my cycle. I'm happy with my diffuser and I expect this will deal with some of my algae problems.
As of now my parameters are:
Nitrites and nitrates are maxed out on my test chart (I did a 50% water change but I didn't test afterwards)
TDS: a ridiculously high 304 (with RO water) but I believe this is just due to the cycling (super high nitrates and nitrites) as well as the co2 which I will stop before adding my shrimp. Also I may have added too much gh booster.
It appears as though the rock isn't drastically raising my kh or gh, so it looks like I should be able to get some CRS down the line.
Any comments or helpful tips are more than welcome as this is my first CRS tank.
