I have just switched over to DI water for my 55 gal. FOWLR.
NH3 = 0
NO2 = 0
PO4 = 0
NO3 = 30 ppm
I have cut down feeding to every other day for a couple weeks now.
60 lbs LS, 50 lbs LR. Stocked with 1 percula clown, 1 springer dottyback,
1 watchman goby, 2 green chromis, 1 C.B. shrimp, 1 brittle star, 1 C.C.
star, 1 Hawaiian featherduster, cleaning crew of 15 hermits, 20 some
assorted snails.
While the tap water I was using did not have any measurable nitrates or
phosphates, I am wondering what sort of other compounds might be
contributing to nitrates?
I was most concerned with pesticide/herbicide runoff, bein' in the middle
of farm country. (Iowa)
Thanks,
Mark

I suppose you could try a nitrate sponge but I find that the best way to
keep mitrates down is with water changes. How often do you do partial water
changes?

I have been doing weekly changes of about 10%.
I did a larger change with DI water on Sunday, and now the nitrates are
down to 20. I'll continue doing 10% changes and see if the DI makes a
difference.
I think probably I was overfeeding a bit and the DSB/LR couldn't handle
the nitrate load.

Mark, if you want lower nitrates, do larger water changes.
Take a look at this article, in case you have other things
adding to this situation:
