filter socks

Any uses for low micron filter socks?For instance 1 micron:question:

sure, if you are culturing rotifers. Use it to drain the culture through, dump the waste water, rinse the rotifers back into the culture tank, or rinse into the tank to be fed.

Excellent plan ,I'm on it thanks!:biggrin:

That's way too fine for rotifers. Use 53 micron for rotifers. I can't even think of any pelagic copepods that have nauplii that small. You could sieve phytoplankton out of water with 1 micron. Most phytoplankton is 2-20 microns.

Aw nuts!water polishing then,other than that useless.

I thought of something...I edited my response. :lol:

Myka is right. I gave you a really lazy answer. Sorry.

The idea behind finding the right sized live foods for larval fish is by using not one screen, but using a series of progressively finer screens.

For example, if you poured everything through the finest screen, it would just capture everything and clog up.

So, for example, in a study by Olivotto et al. 2010

Olivotto, I., Piccinetti, C.C., Avella, M.A., Rubio, C.M., and O. Carnevali. 2010. Feeding strategies for striped blenny Meiacanthus grammistes larvae. Aquaculture Research. 41: e307-e315.

they cultured Tisbe sp copedpods and isolated specific sizes (stages) of copedpods by separation of nauplii, Copepodites, and adult Copepods by draining through screens at sizes 300 µm, 100 µm, 50 µm, and 30 µm.

So you could, for example, use the 1 micron sock to catch everything smaller than 30 microns as the last pass in the series.

Realistically, though, micron screen glued to a holder is much easier to handle than a sock.

No worries,i have some extras left over from a customer,.05 mic .02 mic 1mic.Just need to see if the were applicable to a reef tank.:smile:
