Vacuuming with the 25 micron filter. I saw a difference already. (2 hour video comparison)
When I would only turn the dinos with a rack the white sand would last 15 minutes and by one hour be full blown madness exactly before I racked it.
Now, I vacuummed the sand 2 times in one take, that is let the bucket fill up with 25 micron sock attached. Pour filtered sock water back into the UV compartment, which is 100 bypass to Display area repeat twice.
Here are the videos after 2 hours of letting my lights full blast, no change in intensity.
1st video was taken without my filters because I was in a rush to get into vacumming (I was too excited)
2nd video taken exactly 2 hours apart from the 1st video after vacuuming (filter for my camera was placed to identify the true color of the sandbed)
Conclusion, they are still very much there but not to the degree that I had on the surface before, I hit the vacuum on them. Water temp is still controlled at 82F degrees 3 days in.
