| | Re: Mts?
I've kept MTS in a dirt/sand tank for 3 months - so far NO issues with them causing dirt to muddy the water.
Having said that, I did not rinse my MGOCPM very well, so some chips and floating pieces occasionally make their way to the top of the sand, primarily near the area of the tank where the MTS seem to concentrate. I just leave them there - the shrimp like to pick through the debris, and the pieces are not causing any other problems.
So, MTS do seem to help floaters emerge in my tanks, but cause no problems.
