Thanks,
Its 2.3 x .6 x .6 with two 1 metre sumps (1 a refugium). About 1100 litres in total. Its still only young, but water condition is brilliant, give it another 12 months and it should be getting to a level like some of the tanks the guys around this board have!!. Just got my calcium and Alk up to good levels and only now starting to see some coraline growth (cheers jetski). Going to concentrate on SPS, so still have a big want list for equipment, starting with a good calcium reactor, controllable streams (just uncontrolled units in a the moment), a electronic aquarium controller, a a bigger deltec but no rush on this one, the one I use is a cracker.
Nitrates - 0 - no colour change at all even with double strength (salifert)
phospates - as above, can't detect any.
Ph - 8.3
calcium - 430ppm
Kh - 8.5
