Dinos, manual removal from sand through filter sock

[BryanM]

tl,dr: Vacuum through a 5 or 1 micron filter sock. If the water in your bucket is cloudy, I feel it is quite likely the dinos are in that water that you're likely putting back in your sump.

As some of you will know, I've been battling my 2nd round of dinos, and these have been far more persistent. Almost daily sand vacuuming for 3 weeks, UV, bacteria dosing, and H2O2 dosing, all only kept them managable, but didn't get rid of them.... Oh, and lower lighting, and a 2 day blackout.

On a hunch I got some 1 micron filter socks to vacuum my sand through, and the first thing I noticed was that the water in my bucket was almost 100% clear - Previously I could not see the bottom of the bucket, and I was putting this water back in the sump.

I did this for two days, and honestly the 2nd day was only "out of an abundance of caution" because the sand already looked good.

I'm back up to normal lighting now, and it appears I have won the battle finally.

So if you've found this thread battling these dreaded things, try using a 1 or 5 micron filter sock!

I used a 200 micron sock, which was I normally have for filter sock. Im still fighting them but didnt notice a outbreak or anything and it knocked them back to just a few hold out spots. Ive just been busy and have not went after them again. But seeing this thread, I was like man need to whack em again. Its a good trick to use against them for sure.
