Dont get me wrong maybe it is a good one ,but the one I had was crap i bought it and the NO-2 and the NO3 were off by alot.
the phosphate were tellign me that i havea huge supply in the tank and i had no algae in the tank so, I dont know what to say.
The Ammonia was off the scales when i bought another one it ws bang on \.
Hope you can sell it , or trade it fora few frags
good luck.
