ok....been running the nitrate filter in the continuous mode for about 48 hours at 200 gph. not returning the filtered water to the main tank yet.
the results are the input water is about 35ppm and the output is 5ppm ...the test is almost clear...turns brown with more nitrates....see pic
filled a 60 gallon tank with the filtered water and put in 6 neons......
if the neons are looking good tommorrow...it will be time to return the nitrate filtered water back to the main tank and increase it through put to 500 to 1000 gph......
thanks for watching
