Acros receding

[twabatman2004]

Half of my acros are receding VERY slowly from the bottom. Nothing has changed and all levels are perfect in essence. My calcium is a little high at like 460-480. Anyone had this happen or any ideas? Half my frags are doing this and the other half are doing great. Lps are doing awesome! It's not like a normal fast rtn like I've seen before.

Have you tried any dips at all?

Please list your parameters so others can help tell you what's going on. Tissue recession from the base could be from low Alk, pests, low flow, phosphates, etc.

 

[twabatman2004]

Mag 1350
Alk 8
Cal 460-480
Ph 8.1
Nitrite, nitrate, ammonia, phosphate all unditactable.

The location and flow have all been the same months and they have all been fine until just a few weeks ago.

I havnt yet because they were all based out on large rocks.

I do 5-10% water changes weekly also

 

[Relativity]

I'd change 90% of the water it the only way

try to text potassium.

With cal and mag up that high your alk is low. Bring up your alk a little and let the cal drop.

Try putting super glue or plumbers putty around the bad section all the way up to the healthy tissue. This sometimes stops the receding. It may be caused be lack of flow, lack of proper light to name a few. Sometimes certain frags or corals just do well in a tank. Dont go chasing parameters if the tank is stabel that will only cause further aggravation. None of the numbers you listed should cause a problem if they are accurate.

Ummmm what????

Thanks, will do

This did work on one of my stags, It was receding slowly from the base up and once the plumbers putty covered over a bit of good tissue it grew back down over it. I ment to say in my previous post that some corals just DONT do well but Im guessing you figured that out.

Is that high of a calcium level hurting anything? I don't dose anything. I just have a calcium reactor on the tank.

No, most people shoot for around 420. Long as it stays below 500 or so it wont cause an issue.

Sounds good. Kh need to come up like above mentioned? It's hard to get kh up with the reactor without raising calcium too.

Alk of 8.0 is not causing this problem. The recession is caused by some sort of stress on the coral. The parameters you have are pretty good. They just need to be kept stable for a while. Have the corals grown to the point where they are starting to block flow to each other?

Did you recently do a water change?

Sometimes the exchange of freshly mixed saltwater, lacks beneficial bacteria for the water's ecosystem to stabilize. Many reasons why a system needs to be fully established before high requirement corals are kept.

I've had an instance where I changed entirely too much water (50%) and there were issues of STN. I discovered that the tank water and fresh mix didn't have parameters that matched.

Alk is 50% of the issues RTN occurs for me, normally an alk swing.
One day your clams consume 60% so there's a redundant amount for SPS. Another day it consumes only 10% during the winter and you need to lower the bubble count on your reactor.

They are all just frags pretty much.
