Update on water/nitrate removal systems
the tank remains algae free (a first for me.) I am considering junking the nitrate bio-filter removal system since it keeps cycling for no apparent reason ...every few weeks it will stop processing nitrates and give a faint nitrite signal! Strangely, only for a day ... .
With weekly large water changes (using water containing a 10 ppm nitrate level) but with both units my nitrates are being kept around 3 ppm to 1 ppm by week's end.
My canister can handle the nitrite release with no issue and the in tank algae scrubber handles the nitrates 24/7 when the nitrate bio-filer cuts out (but processes slower without the help .)
Still, the feeding of the nitrate bio-filter with alcohal is getting old, too (I had to up the dose and provide it daily (instead of twice a week) to counter its trying to cycle - still does, but less often.) The Aquaripure is not worth the trouble esp. considering its cost compared to a simple and far smaller in tank algae scrubber!) but I am stubburn ... or rather, is that spelled stupid?
At least my phosphates remain low - about 0.2 ppm and that is very nice and only due to the algae scrubber.

Knowledge is fun(damental)
A 75 gal with eight Discus, fake plants, and a lot of wood also with sand substrate. Clean up crew is fifteen Sterba's Corys. Filters: canister w/UV, in-tank algae scrubber that removes phosphates and nitrates! Also, a highly dangerous commercial nitrate removal unit from hell
