The tokina is actually a good UWA lens but few people use it for taking underwater shots...
You should try taking your tank photos using a fisheye lens...
Be careful of using the artificial LR. It is porous and traps a lot of water in it and the water that is trapped will not be able to circulate and may foul up in the long run. You can PM Indian Chief on this as he used the same artificial LR from JM previously.
What happened to your tank? Usually tanks will not crash for no reason.
If taking macro shots with UWA leses, you will have to crop out the sides of the photo. Basically only the centre portion is usable if you use the UWA lenses such as the 11-16mm ones.
if you want to get rid of all the pests in the live rocks, then it would be best to dip them into Coral RX solution. Coral RX will kill off most of the pests in the rocks but whether it will kill the bacteria I do not know.
