Temperature checkup

[drama07]

So when the light (150W MH 14K) is off, the heater keeps my 23g tank at 80F. When the light is on, the temp is at 82F.

Is there a problem with the temperature increasing +2? Just checking because my galaxia bleached. All my other parameters are in check.

No not at all. Mine swings from 78-82 consistantly every day over 24 hours. The key is that it is consistant. Temp is good. How long are your lights on??

I'd say about 8 hours

My actinics are on from 10 - 10 and my 150mh 10k are on 8 hours. Maybe lower your galaxia if you feel it is beaching.

It is a frag. I drip accimilated(spelling), qurantined and then placed it on the sandbed 18" from the light. When I noticed it bleaching, I moved it to a shady area on the sand.

Currently, the entire skeleton of galaxia is pure white and it looks like it wont make it . The polyps still have color. Temperature swings is known to cause coral bleaching so I decided to check up on RC.

2 degrees is nothing over a time period. I'm not much for quarentining I would give it time from the stress. of moving.

cool thx... I guess ill give it time.

No, temp swings are not a known cause of coral bleaching. Temp excursions above the seasonal maximum are. The distinction between the two is important.

That said, it doesn't sound like you're seeing bleaching. It sounds like you're seeing recession. With bleaching, the tissue of the coral stays intact, but becomes translucent. With recession, the tissue itself is damaged to the point that the skeleton is left bare or almost bare, while the remaining tissue looks healthy.

If you actually have bleaching the proper protocol is to reduce lighting, increase flow, and increase feeding.

If you have recession, it's much more difficult to address because there's no single most likely cause. Some people recommend iodine dips for just about any type of coral malady, but your mileage may vary.

Yeah sorry I meant high temp as the known cause, but I also been told temp swings can cause coral issues.

I'm not sure whether the coral is bleaching or in recession. Doesn't look translucent. I suppose it is in recession.

Anyways thx greenbeans
