Nice looking reef Kim
Welcome back!!
I too had a pyramid snail infestation once. For months every week I was cleaning every snail by hand with a soft cloth to remove the little buggers. That was some serious snail love! LOL~
Keep an eye on your nitrAtes. As the goby stirs up your sand bed (which is not necessarily a bad thing), it is releasing all of the ditritus that has built up and is also oxygenating and killing the anaerobic bacteria that turn nitrAtes into harmless gas. Make sure your skimmer is cleaned and working well so it can remove the floating funk.
Also a temporary prefilter sponge on the return pump (or somewhere along the water flow) would help polish the water. Just be sure to clean it daily until the amount of dirt settles down.
