White stuff

[scooter24]

I got some coral in and placed into QT. Everything seemed ok then after a couple days this monti started to get this film on it and its just spreading all over the piece. The zoas are not happy (having a lighting issue) is this caused by a lighting issue or some sort of bug or algae or somthing? I did dip in revive then a iodine type solution.

It is possible it could be a lighting issue. What is the PAR at the specific locations?

This is under the assumption that all other parameters are G2G.

Your monti is bleaching, what I would do to save it is cut the white part off ( cut more into the polyps side) from the plug and reglue. Move it somewhere else away from the other corals.

Ca,mg, salinity are ok. Little low on ca but not bad im still waiting on my dosing stuff to get in. My buddy in the Netherlands got covid and didn't get to ship them out to me. I was hoping my salt would manage until then but its not perfect. Dkh is like 7.4 id like that higher but like I said still waiting on some stuff. And I didnt know anything about the light, I rented a meter yesterday I put it under the light but not in the water and it was like 36par so I know I need a better light. The light Is 6 inches above the water.

I'll have to look i to how to do this, never done this before

Corals bleaching is due to not have proper acclimating, alk difference and lighting is too strong etc..

Generally, bleaching is caused by increases in tank temperature, particularly when associated with elevated levels of UV radiation or bright light , even from window lighting. alk or CA spikes also cause bleaching.
When water gets too warm, corals will expel the algae (zooxanthellae) living in their tissues causing the coral to turn completely white. This is called coral bleaching. When a coral bleaches, it is not dead. Corals can survive a bleaching event, but they are under more stress and are subject to mortality.

I drip acclimated for a while before they went into qt. I nlw

I havent had any Ca spikes, my dkh is a little lower than I'd like. My light is not proper im only getting like 30par at the water surface (found out after the fact). Water is pretty constant at 78 degrees. Can poor light cause bleaching?

Poor light is causing corals to brown first, eventually you gonna have to get more light to your tank. Birdsnest is a very sensitive specie, what I could think of is you didn’t acclimate it properly?

I drip acclimated it for probably close to a hr. Maybe it needed more time. I have radion over my display i just didn't realize the small light on my qt was this bad. Ill deff be upgrading it at the same time I might just say scre it and put them right in my display. They have been in qt 12 days and were dipped. Should be fine to gamble?

Yes- too high or too low
Poor lighting prevents coral from generating needed zooanthele which is a food source

Not likely but montis could have nudibranchs, and sometimes they munch on the tissue quite fast, just another thought. Look close under strong light.

I havemt seen anything. It was like a while slime. I took my finger and it qas slimy

Ok cool usually nudibranchs hide in shades areas and they do their business at night.
