I am wondering why my tank would have low alkalinity but normal calcium levels? My alkalinity is currently 6.5 and my calcium is 440. What’s the best way to fix this? Water changes? I’ve been reading about calcium and alkalinity online but I’m still somewhat confused with their relationship and so I’m not sure how to address this issue.
Hello All! As the title suggests, I have a green bubble coral that is currently undergoing some tough times. The lower-center portion of the skeleton is gone, but I still get decent extension from the remaining sections of the coral (I'll have pictures posted below). I've had this coral for roughly 4 months, and prior to this injury it would be roughly 9 inches across. This all started after a 20% water change and i believe, but not a 100%, I bumped the coral. I didn't notice any popped bubbles or severe pressing/pinching. This was roughly 2-3 weeks ago from now. Since then, the coral has shown progression and regression in different facets. The coral originally excreted a brown, mucous-like substance, but this stopped roughly 10 days ago (originally thought the coral had brown-jelly). Since then, the sides extend to a decent length, but the middle slowly is deteriorating. Any help would be greatly appreciated and tank specs will be below. Thanks! Tank Setup: 14k white LED's with moonlights (low to moderate lighting) (bubble is currently in a moderate-light location) 532 gph (2 pumps alternating on wavemaker) (anywhere from low to high) (bubble is currently in low flow) SG: 1.026 Calcium: 440 Alkalinity: between 120-140 mg/L (had to use test strips because kit was out of date) nitrates: <10 nitrites: 0 ammonia: 0 also have been using recent iodine supplement (has opened better since using supplement) Tankmates: 2 percula clowns 2 3 stripe damselfish 1 yellow-tail damsel toadstool leather eagle-eye polyps green-eye zoas kenya tree purple-tip, green bubble anemone red trachyphyllia green star-polyp The photos below in order are: the bubble closed up for better view of injury, the bubble a week after injury, the bubble two weeks after injury, the bubble a few months ago pre-injury
