I have a 29 gallon planted tank. Two weeks ago I added DIY CO2. I have a two, 2 liter bottle system. My drop checker has never gotten more than blue green. I still dose Excel every day.
In the past, with Excel only, my nitrate (API test) has nearly always tested between 5 to 10 ppm, with it going up to 20 in rare instances. Now it is nearly 0. It has the slightest of tints beyond the bright yellow of 0
I do a 20% water change once a week and want to continue to do so since I have 12 dGH (4 dKH) and have evaporation (I figure I lose a gallon a week).
My ferts are low tech. I use the label amounts of Flourish Comprehensive and Leaf Zone. I use root tabs for my swords.
I'm not sure where to go from here. So far I don't see symptoms of nitrogen deficiency, but I'm guessing that is a matter of time.
Any ideas about where I should go from here? Should I get a bottle of Seachem nitrogen and start dosing that? I want to stay low tech. I don't have the money to buy a round of dry ferts at the moment though I should in a few months.
