Hello!
I just set up a CO2 injection (canister) system on my 60g freshwater. I set up the pH controller yesterday and ordered a drop checker (don't have it yet). In the meanwhile, I've been pulling my hair out trying to keep my CO2 levels in the safe "green" range of that KH/pH chart based on the KH readings I've been taking & the pH controller measurements.
The issue is that my pH is being pulled down by something in the tank (tap is at 7.5 or so) and I also have very low (barely a degree) of KH. Can someone confirm for me that the Tetra brand KH test uses 2 DROPS per 1 DEGREE (and not 1 drop per degree like other tests)? Also I've been adding baking soda (just a half a tsp) to try and keep the KH up and the CO2 in the safe range. It seems to make the water CLOUDY. Is there something I'm doing wrong? Will I eternally have to battle to keep the KH up, I wonder? Why is my KH so low in the first place?
Also, I've read that either crushed coral or baked egg shells can be put in the filter to raise KH (or is it pH). Please advise... Should I crush the egg shells and stick them in a little pouch or...? Where can I find crushed coral? Which is better?
So many questions...
Thank you for enduring my naivete!
