Dosing Excel with no water changes?
I have a 75 gal low-tech tank and was wondering if it's ok to small amounts of Excel without water changes. I don't plan on doing water changes except for maybe once or twice a year. I want to keep this really low maint.
I've been dosing 2 capfuls every other day and will be cutting back or totally eliminating that soon. The main reason I am doing the dosing is that I've noticed it has helped keep the algae at bay. I started dosing right after I added 60 or 70 stems of various fast growing plants. I figured the Excel would give them a jump start.
Anyhow anyone have any issues with adding small amounts of Excel and not doing regular water changes? Will there be any harmful build-ups or will the plants absorb all of it? I'm not sure what all is in Excel other than co2.
