Tips of SPS blowing up

[madmac]

Gee that doesn't look healthy (as in normal) at all.

The affected ends look inflamed and tender and it appears to spreading to the lower parts as well. Did it happened just one morning or it started slowly and spread from one end to others? May be a good idea to have it remove to some QT first as it looks diseased and do a major water change, JMHO.

all the best though,

Does'nt look like infection. Looks more like oedema caused by ion imbalance

Symptoms around for about a week. Does not spread. Tissue and polyps still in tact. Water changed by 25%. All parameters ok but a little low on Ca (330ppm). Any advice on what this is? Good or bad or neutral for the SPS.....I don't know but other colonies no prob. These two affected colonies no signs of RTN or dying.

Any more insightful opinion on cause and treatment?

New discovery. Seems like when in the dark, the tips don't swell as much. When lights are most intense, the tips swell the most. Still everything else ok.

[Chris]

Now changing water daily (10%) to see if condition improve. No one can tell what's going on with them.

Think now Sugi also face same thing.

Latest update to share.

The bloating tips will 'spread' but it is not a disease. The tips will bloat until it 'explode' but the tips will grow back without RTN.

I can confirm it is due to ionic imbalance. After doing 30% water change and getting the Ca to go back to 380ppm, the tips are slowing recovering to normal conditions.

What a relief!
