Lighting for chalice

[BaaMNYC]

Hello everyone. I have a 30" tall tank and a nova extreme 8 bulb t5 unit with all ati bulbs. I was under the understanding that it shouldnt be enough par especially at the bottom but my chalices seem to be bleaching a little even at the bottom. I'm moving them to a shaded area.

Am I wrong to do so? Do chalices need to have very low light?

Did you have it higher up before moving it to the bottom? What kind of chalices do you have?

I put it on the bottom since I bought it. One I don't know the name of. Bought it at the swap. The other is a mummy eye. It started to bleach on the flattest and highest part of it.

whats your cal and mag and alk levels?

Calc is at 480. Haven't checked alk and mag in a while. What's your line of thinking? I have half a dozen other chalices that seem to be doing fine. All near each other.

How new are the bulbs and how high is the fixture from the tanks surface? It seems it's still too strong. It could be new carbon was added and the yellowing in the water disappeared quickly which triggered the bleaching. Some chalices that have been passed on from one hobbyist to another for several generations are the hardier ones.

480 that's kinda high it should be between 420 and 450. Also if you haven't checked your alk and mag. Then Maybe that can be your answer. Check to see where they are at.

The bulbs are about 6 months old and it's 6 inches from the water? It's on brackets on the tank edge.

Running carbon bleaches out chalices?

its more important to know what your alk is then any others. do you have sps if so you should be checking AT LEAST once a week. i check 2 times per week. try to put the chalices in a shady area and monitor them closely. also try feeding them

dont think that has anything to do with it. think it has to do with maybe ur lighting or maybe flow. is it in a high flow area?

The flow is relatively high.

I remember putting a chalice in a high flow area and it did horrible so that may be the case. I moved it to a less flow area and it flourished.
