[peasofme]

10gallon, 23w compact flurescent bulb office white. my zoanthid, green singulara, and gsp turned brownish/orangish and it is ugly. what corals won't turn brown? what about mushrooms and ricordea? thanks

The problem isn't in your corals, but in your lighting. The coral color comes from little organisms that live in their 'skin' and photosynthesize.

are there corals that won't brown under my light?

Pass on ricordea, but discosoma type mushrooms should hold color relatively well. Also, be sure to run carbon on such a small tank to keep the water clear, allowing more light to reach the corals. What K bulb(s)? How old?

what about Rhodactis mushrooms? 2700 K soft white 1600 lumens indoor 23watt compact flurescent bulb. tank/bulb is about 3 months old

You need to get yourself a proper lamp for corals. What is the fixture? I'd get something like a 10000K bulb. Add another one with an actinic bulb for added color.

That's about the yellowest compact fluorescent bulb you can possibly find...:lolspin:

Look for something with a higher K value. Actually some of the big box pet stores like petsmart or petco have a compact fluorescent screw in bulb which has the deep blue color made for saltwater, and it's like ten dollars.

If it's a matter where you have a cool standard bulb fixture that you really don't want to switch out, you could go with this http://www.nanotuners.com/product_info.php?cPath=74&products_id=623 and keep whatever you want in there if the rest of your equipment/maintenance is up to snuff...

that yellow bulb may also be a big part of the ugly colors.

there is a 29w LOA 6000k pc little spotlight that looks like it would rock on a 10gal.
i'll try to find the link:

most bulbs that will support coral come in the range from 6500k-22000k, I would shoot for somewhere in that range to get proper colour and growth. NOT a home light bulb but one from an aquarium store.

dont buy new corals that have brighter colors, buy new lights so your current corals will color up.

i got a 9325 K bulb today and everything looks a million times better. will a full spectrum bulb look as good?

[Frick-n-Frags]

more reds and yellow in a full spectrum or "white" bulb.

fwiw, that home LOA 6000k(or maybe 6500w/e, cool white) grows coral just fine. grows chaeto just fine too. try it, then say it doesnt work.
