Ricordea bleaching not expanding

[Raquiros]

I have a couple of ricordea florida that are bleaching, not growing (see pictures).

I must confess that eventually y touched them with my fingers or against rocks not really strong, not sure if that hurt them...

My current water parameters are:

Nitrate 30-40
Nitrite 0
Alkalinity 400
PH 7.8
Salinity 1.026 (working on lowering it)

My current light schedule:

Artinic: 9:00am to 10:00pm
White: 10:00am to 8:00pm

Any ideas on how to recover them back to life?

I use trace elements, coralline and zoo-plus once every week and bacteria once every month...

Put in low in the tank with little flow.

Your salinity is fine. Your nitrate needs to come down.

Do you think carbon dosing will improve it?

What about these things I and adding: trace elements, coralline and zoo-plus once every week and bacteria once every month...

Carbon dosing will bring down the nitrates.

If your alk is 400 ppm, it is way too high. I posted this in your other thread about the cyano. Stop dosing, check your parameters. SG, Ca, KH, NO3, PO4 & Mg are the ones that you need to be concerned with.

Cut back on your lighting.

Stop dosing. Move the ricordias to the bottom of your tank with low flow. And then feed them! They like soft meaty food like mysis shrimp. Mine started growing a lot once it started eating.

OP has another thread about cyano in his tank. Feeding corals may not be a good thing to do at this time.

Thanks... I haven't start dosing yet, will need like three days of research before adding a single drop of vodka in my tank....

Any suggestions on KH and PO4? Where should I begin to do the things right? Cyano keeps growing ugly brown hair...

Go to the reef chemistry forum. There are many good articles there.

NO3 & PO4 fuel cyano & algae. You try to get NO3 down to less than 1. PO4 should be less than .03.

Your KH(alk) should be measured in dkh. If your 400 is correct that converts to about 20dkh which is way high.

So the Ricordea stays bleached, they seem to be ok as they open (like a penny)and they kind of close every day... they still glow a bit in artinic lights.

I placed it in the bottom half of the tank without direct light...

I have the following products, which any of these will help them to recover?
