A little update,

Cyano still a small issue, bubbles are nowhere near as bad as they were and I"m still scrapping it off whenever I do water changes.

Iodine dipped all the corals, found no pests. Acros are still looking rough but don't seem to be receeding since being fragged. The pink birdnest is actually growing! The green chalice extends feeders every night, the new orange one (added on friday)has yet to do so but had not receeded or bleached in any way. The bubble added at the same time looks fantastic.

The mandy has doubled in size in 1.5mths that it's been there. The bi-coloured blenny is bold enough to stick around the mated clown pair We added a blue-sided wrasse on friday, seemed to be doing fine. Eating mysis, swimming around and now we haven't seen him in over a day The only thing that might have affected it is temp on Sunday as we couldn't turn on the air but NOTHING else was affected.

Parameters:nitrate 0.25 nitrite 0 ammonia 0 Phosphate 0 Cal 440 Alk 7.4 (this is the only one that I'm having an issue keeping steady!) Mag 1400
