Yup, I've got the KNO3. Been dosing to keep nitrates at 10ppm

Oh, yea. A phosphate test showed levels off the scale immediately after
the 50% water change. I don't understand that. I can only assume the
test is accurate. It reads 0-0.25ppm for my tap water.

I run almost a 50% water change last night. I added a little KNO3 to
keep the nitrates up to 10ppm. I am going to dose fertilizer tonight.
(it got tool late last night). Still pumping CO2. pH dropped to 7.1

Just make sure you add plenty of KNO3 and KH2PO4.

Keep up on it and keep things clean and you'll be alright.

No BGA as of last night. pH=7.1 NO3=10ppm PO4=off the scale

I changed about 30% water while vacuuming, and installed a phosphate
sponge I just bought. The vacuum really didn't pull much out of the
gravel. The phosphate spong is supposed to remove 20mg/L in 30gallons
of water. According to my calculations that'd be 10.9mg/L assuming I
have 55gallons of water in my 55 gallon aquarium (which I probably
don't). The directions say "if the phosphate levels ain't 0.02mg/L or
less after 4 days, change the sponge for a fresh one"

I must say I have learned much during this experience. Thanks Tom.
