My koralia is due today...just tracked it.
My tds meter is EZ tds. works great. I had a problem with a diatom outbreak, ordered that meter and found out the ro/di water I was buying at fish store read 90 on tds meter.
they changed all the catridges and it still read 76...so needless to say today is my first day with my own ro/di, and it reads all zeros :cheer: :cheer:
Just got first garbage can full, mixed up ready for a 25gallon water change tomorrow. then another one next weekend.gotto gid rid of that crap
