ammonia and nitrite are the ones that need removing, nitrate is ok within reason...What is the best test kit to use that's pretty cheap?
I've heard that test strips aren't great, so would a tetratest liquid ammonia and nitrite test be any good?
Also, is it nitrite or nitrate that's most poisonous?
Thanks!
I may go with the 6 in 1 test strips as they're only £5 and i don't need exact readings, i only need to know if the levels are getting out of hand
I've found a Laborette test for £16 which has ammonia, nitrate, nitrite, GH and CO2 tests. I'll be getting this one
I've seen a number of posts over the years of people kind of struggling with the laborett tests. I really think the pecking order is Salifert, API, Nutrafin and then a gap... WD
