After having trouble keeping the
ammonia levels low in my
QT a few weeks ago I discovered that the problem was the source water. The water coming out of
RO unit gives
ammonia readings of 0.25-0.50
ppm. Since I hadn't changed the
RO membrane or the carbon filters in a long time I went ahead and replaced those. Readings are still the same. If I test my faucet water I get similar readings. I have been buying water from
LFS which tests fine, but I'd like to fix the situation. Is
ammonia something that an
RO unit should remove? I was thinking of buying an
RO/DI unit for the tank later on but I don't know if that will solve my
ammonia problem. Anyone else ever have this problem?
