Two quick questions..(ive read thru all posts on this.. Just wanted an updated answer
1. Ive gone thru several ph meters.. Pinpoint . Aquacontroller 3 and milwakee combo ph/tds meters.... All of them eventually fail to calibrate.. And i always keep them wet. I was especially disappointed in the Aquacontroller 3..even after i bought a new probe.. Eventually failed to calibrate after 6 months.. And i kept it clean. Is there a better/more reliable ph meter model that i should be looking at? Mainly i just need to make sure my r/o tapwater mix for discus tank stays consistent without having to always use seachem neutral regulator... And also keep a close eye as i use muriatic acid to drop ph and try to induce spawning in wild discus
2. any recommendations on a spectrophotometeric nitrate test that works great. (one where just put tank water in cuvette and it gives an accurate reading. I guess it would need to be a low range one.. Ive scoured.. Looked at outside reviews on hanna, hach, etc.. But loys of variability... And again..i just wanted an updated experienced opinion from the group here
Thanks all for your time!
