I did the plywood covered in resin for my snapping turtles pond in the back yard. it came out great, and worked great.Been a very long time since an update so here we go.
In May I had a few issued. My tank's alk dropped to 3dkh due to a reactor malfunction. (clogged) with the amount of SPS I have My tank went from 8.5 to 3 in just a few days. Lost an inch or two from almost all tips of SPS.
I also had some return pump problems and installed a new Reeflo Dart/Snapper Hybrid and I love it.
I replaced the ETSS 800 Skimmer with a ATI Bubble Master 250 modded with red demon NW impellers. The skimmer is rocking and it's 140 watts less then the ETSS.
Next task this summer will be a plywood sump (coated in fiberglass/resin) DIY thread coming soon.
Other than that the tank has recovered from the alk issue and is looking better everyday. Corals are all looking good.
