I'm planninng out my sump, and have run it through in my head a number of times. I know there's a way to calculate the sizes and positions of the return chamber, suction line, etc so that the whole system is "fail safe". I.e. due to power failure the sump will never overflow, and due to clogged...

Just curious - were you running everyting off a ground-fault outlet??? I NEVER and I mean NEVER plug anything in thats even NEAR my tank unless its in a properly installed and tested ground fault outlet. For my safety and my fish. You can hardly beat the peace of mind for $10 it costs to get a...

I found a really good deal on some dolphin mag-drive pumps on everyones favorite auction site. Got a dolphin 900 shipped for <$40.... Jeff

Thanks for the reply- No, the cleaner crew died through attrition over the past 3-4 years that I have mostly ignored the tank. (Amazing what lived, but a LOT of stuff did... And Im talking tank-in-garage little to no light, no water changes for YEARS). A bunch of snails lived, and crabs, and a...

OK, tank has been up for 7+ years, however was completely ignored for about the last 2 years. Live rock is still "live" and, for the past 4+ months Ive been taking care of it again. I have lots of tube worms, about a dozen small hermits, handful of small snails and a couple big ones, and lots of...

Just as an added note for anyone following this... Further research showed me that the Luxeon V portable white is the ultra high output, but limited life version (120 lumen, but 1000 hr life) However the Luxeon III is rated for 100,000 hr lifetime. Output is a more modest 60 lumen. And a little...

This is some interesting stuff. I read the datasheets about the luxon V white, and the highlights are: http://lib.store.yahoo.net/lib/ledsu...eon-StarVW.pdf Output at 20C - 120cd nominal Color temp at 20C, 700mA - 10,000K 50% dropoff angle - 120 deg All that sounds just about perfect. They have...

I finally re-started my reef tank after a several year hibernation... (Tank was still up, but nothing alive but the critters on the rocks). After moving to my new house last summer, I finally moved the tank into position and am starting to turn it back into a proper reef. My next project will be...

What pump are you mentioning that will flow 600gph for $30?? I *really* want to build a sump now that I have a new house, with a basement workroom right under the tank. I'd need a pump that will flow with ~8-10' of head, my tank is a 55... Any suggestions WELCOME... Thanks Jeff
