I have also been using the UV sweeper to handle dinos and some cyano on the sand. I have been very impressed with the results! I used the sweeper a year ago and did not get great results. This time around I have held the light for a longer period of time at each spot (30 seconds minimum). That has worked well!


. I will keep that in my arsenal. I like the idea!
. So I’m trying to study it better. Wish we could get a Dino’s section here to learn more
. I’m going to order some and try it out.
