I run 4xT5 bulbs on my 40G breeder. These SPS frags are very close to the top, but have lightened since adding them. All have excellent polyp extension.
In particular:
The LE Setosa is doing well and has been growing fine, no color change.
The Teal Stag seems to have lightened just a tad.
ORA Chips Acro has lightened a bit.
Cali Tort has lightened a bit but has only been in the tank for 2 weeks, may lighten more.
Plum Crazy has lightened a little.
Purple plasma has lightened a lot and the green polyps are now whitish.
I don't really mind any of the changes much except for the Purple plasma. Without those brilliant green polyps it's just not nearly as flashy. My system is very low on nutrients (I run Elos Filtra M zeo). It was never meant for SPS but alas, things change, right? Anyways, the question is whether they have lightened because of not having strong enough light, or because I didn't feed the tank much and it was running zeo. Over the past week, I started trying to spot feed the corals Rods Food which I had on hand. Nothing seems to have changed but it hasn't been long either. Someone suggested the food issue, otherwise I would just have thought light.
