Supplements questions.

[CLR48]

I just bought some reef suppliments from a lfs that's no longer going to have daltwater stuff so everything wasarked way down im wondering if all this stuff is still okay to use. Heres a picture of all of it.

the only dates are on the two small white bottles and the date is may of 2012 but they were only $1 a piece.

If they have never been opened they should be okay.

Agreed, but be careful dosing stuff just because you have it now. Make sure you take it slow and only use what you think you need.

I would take it a step further and say don't dose any elements that you can't test for.

 

[CLR48]

Okay thanks I got all of that for $20

That's a good deal. I would test first over a couple of days and see what you're getting.. Then dose accordingly.

Yeah. What about the phytoplankton and zooplankton?

Those should be fine (watch it with the phyto that you don't dose more than your system needs, though! I did and caused an incredible greenwater bloom, lol!)

A better use for the phyto (if it's live) may be to culture live zooplankton such as copepods. Don't culture rotifers unless you're willing to spend a lot, as they eat themselves out of food very quickly.

If the zooplankton in your bottle is live, you might add a large amount to your system and let them breed. If not, use as target food for filter feeders or give it to zooplanktonivorous fish such as anthias.
