Red Sea supplements

[IMAGNDAT]

I just recently started the hobby again, and still have tons of supplement bottles from red sea, like calcium alkalinity No3XPo4 bottles, with exp dates, are these bottles still good or just toss them in the trash?

The calcium, alkalinity, and magnesium supplements will be fine forever. The No3Po4x might in theory degrade over time, although I'd probably give it a shot. Anything organic is a bit suspect.

Thanks, guess I'll give them a try.

You're welcome. Good luck!

You might want to check for precipitation in the supplements. If there is a significant amount, some warming and stirring might help redissolve it.
