Non-photo Pieces.

[ginrin]

Is there a list of these corals and see threads of dendro and rhizos in LPS forum?
Does a listing of non photo corals exist?
Thx

At my knowledge, not - a full list of species. Bits and pieces by family are mentioned here and there.

Had you seen such list somewhere, or would you like to see the list of non-photosynthetic corals?

I have no first hand knowledge of dendrophyllia and rhyzos, usually different group of people keeps them. And another group - high flow fine filter feeders.

Thx Dendro.
Trying to set up a non-photo tank and wondered what corals need light or very low light.I'm planning on using just actninic and moonlights.I'm looking at dendros and rhizos,plus a few others.Am I on the correct path? Thx

Dendrophyllia and rhyzos are out on my experience, sorry. Should be fine at actinics, as any non-photosynthetic corals. I have some NPS in a dark tank, but different corals. Quite good.

Hi Dendro,What part of Canada are you from?I'm in Toronto.
What lighting would you use to retard algae growth?
I'm thinking of actninics and moonlight only,but someone told me actninics produce a lot of algae.Thoughts and Thanks

Dendros and rhizos should be fine in little to no light, they don't use it at all anways. Mine are in regular reef tanks but tend to open larger at night. Very easy to keep as long as you feed them.

Hi! Toronto too, East end.
I didn't try the pure actinic light, only 50-50 combo bulbs, actinic: 10,000K, can't say. But tanks of Daniela Stettler, joanxavier and at Malayan forum are under high intensity metal halides, and no traces of algae. I believe, that filtration should be adequate (although mine is so far far from perfect ).

Phosphate remover helps with keeping phosphates in check and algae too. But if the rock is covered by green microalgae, and keeping PO4 at zero and NO3 quite low didn't help, then "cooking" the rock (bacterial cleaning without light and food, with water flow only) and improving filtration could be the way to go.

I was under the belief that dendros do require light and are photosynthetic. I can't show you a source to tell you that's true but you might want to find something saying it isn't before you keep them in super low light. Another key point is that my dendros open the fullest under lighting capable of maintaining SPS. I am sure they don't need that much to do so but I figure as much as an Acan needs. Rhyzos on the other hand are clearly non-photosynthetic corals because they are almost completely void of pigment.
