Nitrate And Ph Test Kit?

[Whitey_144]

Hi,

I just started a thread in the emergency section because 9 cardinal tetras died today, ive also had a BGA war.

My question is, are there any other way to test PH and Nitrate for not too much money, but better accuracy than the API liquid test?

I have the API liquid test kit and whilst ammonia and nitrite is easy for me to tell, nitrate is very hard to tell and so can PH be, especially as mine usually borders on the low PH/high PH area meaning I do 2 tests, and get just as confused!

Thanks,
Adam
