well....a few months ago (under my old fixtures) it was a brown "green" Millipora so....guess I went from one extreme to the other...lol

I also started Bio Pellets about 3 months ago.....so should they not supply some additional food for them?

I would say to drop your daylights down to 5 or 6hrs (temporayily but maybe 7-8 after colours come back).....keep your actinic period 11 or 12 that is fine. If you think you have a low fish load and dont feed much, well you can up those....possibly significantly. Also Amino Acids might help till you get things back in order.

**edit** bio-pellets is another clue...you need to feed a lot more after your biopellets get working. Sounds like you have both problems....too long of a photo period and too low nutrient/bioload/feedings.

New bulbs could help, or make the problem worse.

If your bulbs are old, and/or you were running them for longer then normal, that could cause a bleaching problem.

New bulbs will be brighter. With little zooxanthellea left to protect them from light damage it could cause them to give up the ghost. If you do get new bulbs, you might want to reduce your light cycle even more, or raise your fixture up until their color starts to return, then slowly go back to normal.

I have carbon in one and Bio Pellets in the other

My fish are
1 Hippo Tang
1 Sail Fin Blenny
1 Mandarin
1 Coral Goby
2 Purcs
1 High Fin Goby
1 6 line Wrasse
1 Yellow Tang

I feed once a day.....either 1/2 a cube Mysis, Brine shrimp or a pinch of new life spectrum pellets........with a pinch of algae/sea weed pellets every other day

Ya, that's my guess too.

Kinda light. In my tank with 12 fish (bigger than your load), I feed mysis or plankton twice a day, a full sheet of nori everyday and I toss some various pellets and flakes in when I'm hanging out at the tank. the frozen is usually at least a 1x1 square, rinsed in a strainer.

What size of tank are you running man?

Am I wrong in interpreting that Bio Pellets will provide a food source for my corals as well as help with trates/phos?

They all look bleached and starving. start feeding these corals and not fish food. Give some amine acid like the one from Zeovit and coral vitalizer from zeovit. Fauna marin have good coral food too. They are in very bad shape and they will probably die if the conditions are not changed.

I would reduce the light to acclimate them to the new light slowly and feed them each day.

None of them have the right color and look normal.

I've got a 180 with larger fish. I haven't used biopellets, but have heard they can starve the tank of PO4 and NO3, both essential in small amounts to fuel growth. Not sure about them feeding corals, I haven't heard that, but I haven't looked either.

Some companies claim the bacteria that feed on the bio pellets, no3, and po4 feed corals. I have never seen or heard of hard evidence.
