my 10 gallon tank still in fishless cycle already 10days and this morning reading ammonia-0.25ppm,nitrite-0ppm,nitrate-40ppm. Yesterday 0.5ppm ammonia, nitrite-0, nitrate-80ppm. I do 30% water change yesterday and this morning 50%. Its suddenly the nitrate go 80ppm. How to maintain the ph level at 7.4?
