In preparation for my two week trip starting next weekend, I put together a quick auto top-off so that the tank won't run dry. It was fairly quick and easy using the float valve that I got with my RODI a couple years ago. (This hobby teaches you to never throw anything away.) I used a piece of 1/8" plex, attached a leg so that it can't move and stick the float valve to the side of my sump (bucket) and attached the float valve and supply hose. The other end goes to a 4 gal plastic container.
As an added bonus, the divider in the sump has drastically reduced the amount of bubbles returned to the tank. Stay tuned, new corals tomorrow 9-10 frags, $5 each. Even though I'm out of town for a couple weeks soon, I couldn't pass up those prices. Mostly zoas and montiporas. Hopefully pics tomorrow
