[Trail_Mix]

Anybody know of a good test kits for copper? I've heard the API test kits are extremely unreliable. Thanks!

i personally think that API makes the most reliable of ALL test kits out there...............im assuming ur asking cuz u have inverts? or loaches? well, u could get a TDS meter which would help too. they have a few decent ones on ebay for like $15-$20.............

API is the most reliable to most ppl, unless ur making a statement only about the copper, but i've never used that but i have used the rest like ammonia, nitrates, nitrites, phosphate, pH, high range pH, etc. and no probs. for me evar

Yeah, I was speaking specifically of the copper testing kit. In general I use API test kits for everything, but I've heard the copper one doesn't really work for **** from multiple people.
