Aquarium Advice Regular
I have a natural CO2 system in my 36 gallon. I might just have a faulty test kit, but lately I've been getting really, really high nitrate levels (160 ppm and up, with little change after several pwc), and my pH came up at 7.4 one week but 6.8 tonight. I read that too much CO2 would drop the pH, so I started to wonder if my off readings could possibly be the fault of the CO2. I had it on the highest setting but based on the product info it's only meant for 20 gallons, and on top of that I have a bubble wand running. My fish (just one goldfish atm) seems perfectly fine, but today he did seem to be going to the surface more than usual.
I've just started planting my tank and only have 3 anubias right now, and I'm only beginning to get into the lighting issue. This just doesn't seem like a likely cause (in fact, I sort of figured I didn't have enough CO2), but I thought I'd get a second opinion from people who know more about CO2 than I do.
Thanks for any help!
