Wow Steve, just heard about this on Marc's PodCast. Not cool. Glad to see you are taking it well...I know I have had some serious issues and a lot of swearing but after the initial shock (or shocks
) I seem to get back on the horse.
I am surprised that you didn't have water ready. I remember when I visited I saw your empty holding tank but didn't really think anything of it. Right now I ALWAYS have 90+g SW aged, aerated, and stirred a few times/day. And I always have 75 - 90g of RO/DI on hand. Both are heated as well. In fact I did that based on input from Weatherson's site, but I thought you did the same.
I am planning on ripping out my 1,200 sq. ft. deck and installing a tiered outdoor area with a spa, BBQ, seating etc. When I build this, it will be like a house foundation, retaining walls, and multiple sumps. One sump will be 1000g for RO/DI wastewater, which I use to water my vegetable garden. (it's high in nitrate, phosphate, and minerals) One 500g sump for SW, and one 500g sump for RO/DI. An additionaly 50g RO/DI will be inside the tank room for top-off. I know it sounds like overkill, but I seem to be adding to my system over time and I want to make sure I have the capacity for the future.
The best suggestion yet in this thread is a low-water cutoff. My last disaster was when a seam split on my multi-media reactor and although I had it mounted on top of a sump for leakage, pressure actually made the water spray out onto the floor. It emptied my sumps, overflow, etc. and in the end fried some electrical outlets causing several breakers to trip. Long story short, I got everything back in order and the tank inhabitants were fine. I had enough water to refill the sumps and get her going again, but a low water cut-off could have kept the smoke inside some of my electrical components.
I can't wait to see what you will do to modify your system and how you will deal with aquascaping. Good luck!
