So does anyone else do this ? Get little stick with string attached to it put it in the sand to see how your flow is flowing I use 3/32 aluminum tig wire cut to 4 inches 7ins and 11 in (got a 3 in sandbed) and I put them near my corals and open areas to see the flow directions and speed. The extra part that I plan on doing is leaving them in the tank for a day while recording it and viewing the video to see how it runs throughout the day ( using Nero 3)
