Bleached out Stag

Huskymaniac · Apr 18, 2020

I replaced the quartz sleeve on my uv sterilizer and my gigantic stag seems to have bleached out a bit. Assuming from a bit of light shock. I set my lights to go through a 2 month acclimation with a 20% reduction. Anything else I can do? Most of it looks ok except for the areas directly under the light.

Your uv should be in a housing how can it shine to the tank????

Agreed, are you shining a UV sterilizer into your tank?!?!?

The quartz sleeve had calcium build up on it so when I put the new one on it must have cleared the water a bit more and shocked the coral.

Not a chance do you have damsel or chromis in the tank? They will clear out the under side of stag horn and lay egg

Other than lowering lights.. maybe brightwell Aminos? Brightwell and WWC state hey help heal corals. Believe I heard this on BRS.

I would love to see a fts, those colonies look nice. Everything in the pic looks a little light colored but it’s probably the pic itself. Can you get a better one or a top down of the coral? As long as it’s not loosing color more everyday it should recover I would think.

Here read this thread and look at the picture i post to see if it the same for your stag

Help - Green Slimer issue

Man I wish my slimer looked that good! Well it does, just no polyp extension. One of these days I'll be rid of that darn flameback angel. Then I might actually start to see some polyps.

Do you think a 20% reduction is enough? Wish I had a par meter to measure before and after.

Awesome tank! I would raise the lights a little if everything lightened in color. If it was just the stag that lost some color I would just make sure it’s not continuing to lighten or maybe just raise the lights for a few days. I can imagine a well functioning uv light could cause the water to clear enough to loose some color for a bit.

Yes. Remember though its one coral that isn't doing well. We don't want to risk stress to other corals by the changes we make for one coral. So be careful on what you may do to help the coral. If it continues to get worse cut off the damaged branches.

will do. Doesn’t look any worse today and it still has full PE. Hopefully will recover In time. I dont think the reduction should be too bad. atleast my alk consumption stayed the same according to my trident so things are growing at the same rate.

Last ICP nitrate was 1 and phos .04

C. Eymann · Apr 20, 2020

If you want to darken up color a bit, Id feed more, maybe try and get nitrate up to around 5ppm and get phosphate up to .08-.1 or so.

Your tank looks beautiful, but resembles a Zeovit tank tbh, which are still beautiful but more pastel/paler colors are common in with ULNS

Get a nice test kit for both NO3 and PO4, very gradually increase feedings---> raising N/P until you are happy with coloration.

Or completely keep doing what you are doing, its obviously working very well, but if you want bolder colors, you will need to elevate nutrients a bit more.

Just my .02
