Flourish Nitrogen (approx. 3 mL, 2x per week)
Using the "expert" formula on the label, and using your tank volume
approximation of 60gal, that would be the equivalent of 1 / ((0.05 * 60) /
3) = 1ppm NO3 each dose. So, you're adding the equivalent of 2ppm nitrate
each week. That's doubtfully enough and also doesn't seem to jibe well
with the 8ppm you mentioned above. Some discrepancy can be attributed to
testing error and the estimation of water volume, but a 6ppm gap seems
wider than those things can account for. Do you have nitrate in your tap
water or big/numerous fish (i.e., lots of nitrification)? Does the nitrate
level go down from day to day or does it seem to be building up?
I do have a rather heavy load of rainbows and congo tetras in the
tank. They are not fully grown, but, I do feed rather heavily once to
twice per day. That may account for it. As far as my tap water, I haven't
tested it, nor have I tested my water during various parts of the day. I
agree with your statement that Seachem's product can get pricey with large
and multiple aquaria, so I am considering trying out the PMDD soon. I will
run the above tests and let you know. THANKS!
