Found what appears to be another brittle star come out of the rock after lights went out the first night, however have not seen it since. Discovered afew little fanworms aswell, apart from that have not seen much else life !
Also fixed up my return pipe so that it comes up and into a 'T' and then out over each side of the weir via 45's. This looks much better now:
DIY 12V Auto Top-Off - I got annoyed with the float valve that I had purchased as I could not find a thread to suit the connector on the valve. This system also relied on gravity to feed the water, I didnt really like the system to tell the truth, so I thought up this idea !
Parts :
240V -> 12V 1000mA Transformer $FREE - Found in drawer at work

Piece of clear acrylic for holder - FREE - scored from work scrap bin

BCF 12v Camping Shower, remove the shower head and butcher the power cable, leaves you with a neat little 12v pump with a decent length of hose attached
NOTE: have removed the spring, just in case rust was to prevail !
Then just solder it all up, not too hard, sheesh I even managed to get it right. I left my piece of acrylic at work though so will pop in tomorrow and grab it, then use the trusty toaster to bend it up into a nice bracket
