OK, who's got well water and a question...
I've got well water. It's good, pH 7.0. No negatives like high nitrate/nitrite. I don't have my gh/kh before me but it was fine when I checked. When I do 30% waterchange every week or two, I run straight from my sink tap into the tank via python. I've run planted, fairly low light/low tech for a year (a little 20g) and am setting up a 10g shrimp only and a new 30g. I've used Excel to bump the carbon up on the 20g, which has a 40W compact flourescent. I've not used ferts, trying to just let it mature and stay low input. However, I recently got BBA going in there, ... yikes, I'm working on it with cleanup and 2x recommended excel daily. Here is my big Q: OK, the plants do better if I supplement carbon (e.g., excel or CO2, which I'd rather not do). However, my well water must have a lot of CO2 when it comes from the tap, right? So rather than do yeast, or even do Excel, what if I found a regimen of daily addition of X ounces of well water, say in the morning just before the lights come on - to basically use it like a daily CO2 addition, either with or without Excel supplementation? Also, thinking my water changes might be the reason I got BBA going - being addition of 30% well water, which is a sudden, substantial "change" in Co2, which favors BBA? Any thoughts appreciated... I know I may need to do more frequent, small water changes and use ferts in the substrate, which I"ll start doing but just wonder about this well water/CO2 theory. Comments appreciated.
