Nitrates registered at 0
PPM--tested twice because I didn't believe it. I hadn't tested nitrates in a while since I needed a new kit and didn't have any money

But, got it today and tested at 0--I even shook the 2nd bottle for like 3 mins the second time I tested, since I've heard sometimes the mixture gets separated if it sits around for a while. The tank is the 20 gal, inhabitants listed in my signature (still not fully stocked). All that's in there plant wise are 3 medium java ferns, and then there's the green water algae that I cannot get rid of, but I suppose at least it's eating my
nitrate. Would that and the jf's be enough to reduce my nitrate to 0, or might there be something wrong with the
test kit? (it's an
API liquid test)
I do generally vacuum about half my gravel each week when I do a
water change, but I will make sure to do an extra good vacuum this week.
Feeding--the
betta gets fed once or twice a day depending on how fat he is from eating the planaria and worm things.

I drop in a wafer or several pellets for the catfish once every 1-2 days.
I can't figure out why that tank always looks so dirty...
