Hi guys!

About 10 months ago i was trying to find a way of adding a sump to my max which did not involve a pump in the tank and a pump in the sump as i had heard that getting the feed and returm correct could be tricky and would need to be constantly monitered.
I was quite disapointed to hear this as i was real eager to get a project going on my new hobby. So undetered i did a little research and thought about putting a sump above my max that could be housed in the garage as...

Im Completly baffled and am feeling soooooooooo sorry for my beautiful anemone crab.
I thought he was dead after i saw a whole crab lying on a rock which included both claws and both duster like appendages, but after a few hours my girlfriend noticed that he was hiding under a rock, he was definatly alive but had only six legs and nothing else!
Ive done as much research as i can on the net but non i have read have seen their crab loosing 'both' their claws let alone both their 'dusters'....
