Bad batch of Instant Ocean

[smokinreefer]

i think we need to look deeper than just getting caught up on this 40% volume thing...

the fact is, the ALK in the new water was way off from what it should be.

mind you, if it were only a 5 gallon change, the bad water probably wouldnt have had such a detrimental effect on the tank. hind sight is 20/20 though. who could have known...i never test ALK of new water before i do a water change. i have enough trouble testing the salinity and temp!

but again, that still doesnt change the fact that the water was bad.

JMHO.
