Hi Malc long time no speaky hehehe....

Love the project! very nice bit of kit you guys have developed there!
Been updating my bits and bobs so that I can start developing some bits for my small reef tank etc and cant wait as along with the usual temp reader, im also looking at adding water level detectors (going to try sonic sensors as got a few laying about) and when funds allow, will be having a go at using the larger powered LED's to make a new light unit where i can control dawn to dusk etc (thing with LED's are the large amounts of them you need for penetration/cover on a reef tank)

If I can get anything that remotely resembles the quality bit of kit you created i'll be a very happy chappy

Mark.
