Hey! What's going on with the tips?

[dynamictank]

What tips you ask? Lol
My corals for the past two or more months I have been having an issue with my corals. The tips have been loosing color to the bone n only a lil as u can see in the pictures.

I believe this is called a tri color bonsi or just a purple bonsi.

More of the purps!

Here Is a colony which is large bigger then my hands together n a loose piece if anyone wants to buy it but I rather keep it! But it also went through like a burn or something not bleaching.

Even my acan doesn't really open. Like it used to.

All tests are good.

What is this urchin? He started out in a tank from a tiny thing.

U test for alk? My guess is it's high?

 

[NYreefNoob]

recently change bulbs or start dosing a carbon source ? and +1 of checking alk which is what it looks like

 

[jetthril]

what about your phosphate? what phosphate binder do you use?

judging by the algae growth in the sand, you either have some silicate or phosphate in the system.

I had fought a similar battles with phosphate (ran out of phosphate binders, phosphate was detectable, NO3 was 0, pH, Ca, Mg, were all normal), and my tricolor SPS, totally browned out.

After get my new GFO, phosphate came back down to 0, within 2 month, my sps is as colorful as ever.

Try to run a phosphate test on your system.

Can be a number of things from alk being too high or adding anything too fast like carbon or GFO.

 

[NYreefNoob]

plus those brand of kits arent that reliable and check age on kits

 

[ZANYMASTER]

Definitely a Phosphate issue.Some corals don't mind the higher PO4's but not the SPS.

Jesse you need to stop using API test kits.

It is really hard to tell from the pics, but it looks to me like the acro tips and acan are getting nipped by something--the urchin perhaps or what fish do you have in there? A rabbitfish by any chance?

 

[dynamictank]

No I no my fish species very well API I use and red sea as well. I tested phosphates none present as for silicates I even changed all my ro/Di unit Tds is at .03. I also added a phosphate reactor but I am running sea Chem phosphate remover. I changed bulbs as well. I started using aqua vitro salt. I also started esv 1-2 n I had white eggs starting to bloom.

For algae I think the next step was gfo in the reactor n remove sea Chem n purigen I have in that.

Alkalinity I thought I tested it low but calcium wasn't high so shouldn't give me a wrong reading.

I started cleaning sections of the sand which has helped reduce algae on sand.
