Thanks, another question......what is a normal range for nitrates and
phosphates?

My light is flourescent.....should I still change it?

Thanks for your input.

For nitrates it's less than 40ppm, preferably less than 20 if possible.
I can't recall from memory what Phosphates were.

OK, just a dumb question, I have tested my water and all the readings are
perfect, except for the nitrate's which are too high, so what do I change,
or add to get them into the normal range? How can all the other numbers be
OK and just this one way off? I have 3 ponds and one 50 gallon house tank,
all treated the same way, and yet only have trouble in one pond. Help me
understand what is going on. I have 2 fantail gold fish in the 50 gal. 7
....4 inch comets in each of the 150 gal. and 7... 8 inch comets in the 300
gal. all 3 have pondmaster pump/filter systems that are 3 times the required
size of the amount of water. If that info helps. KatAZ
