Our reverse daylight timer turns the light off in the afternoon. I think
a day/night cycle is best for the plant and animal life that live in the refugia. And, my reason for using the RDF concept is to stabilize the pH. Plants "exhale" O2 during the daylight, "exhale" co2 during the nighttime hours. (I think!) It's the balance of O2/CO2 that influences pH. BUT, we grow mangroves in our sump. I think the exhaling part is done through the leaves. Is my understanding of RDP going to work with mangroves exhaling in the air, not the water? Got some caulerpa, and some funky other stuff, in there just in case.... |

I like Reverse Daylight because the algae seems stressed when it has the lights on 24/7. Just try to use several types of macroalgae so that if a bit of caulerpa dissolves it won't be all you have and thus wipe out the only source of RD benefit.
The Chaetomorpha sp./Spaghetti Algae seems to be as good as the hardiest Caulerpa, Racemosa. I need to harvest my Chaetomorpha again. ------------- Reefkeeping Tips, & quick, easy setup tricks: www.utahreefs.com/forum/forum_posts.asp?TID=9244 Pay it forward - become a paid WMAS member

Meterman, It has rarely been a problem in tanks I've seen. I kind of like the variety of it. It grew then declined in my jug, so your tank conditions were more to it's liking.

I have had both 24/7 and reverse daylight the macros seemed to grow more under the reverse daylight. but both seemed to work for my tank. right now i have reverse daylight.

Since Mark just made a plug for SeaScope, I'm going to chime in hear and say that for all of you who like SeaScope, I highly encourage you to pay your membership NOW. Check with Mark to see if you are current, and don't wait any longer. Adam ------------- Come to a meeting, they�re fun! |

The reddish algae I believe is called asparagus toxiforma. My rabbit fish and achille's tang would happily munch it first. I think it's good stuff. Not the most gorgeous of my macroalgae, and it grows quickly. Seems like most people talk about it more like a "weed" than a desirable macroalgae. I like it though. Connie, I have macroalgae you can have any time. Mark's closer to you, though. ------------- Renee and Damon Weimer Tankless in Hawaii |

If I remember right, I don't think the algae mark and meterman are talking about is Asparagopsis taxiformis. A. taxiormis is a macro isn't it? I think the redish stuff they're talking about is really fine and looks like cotton candy in the water. I don't know what that cotton candy stuff is. I too got a little of it from Mark's Chaeto, but the cotton candy stuff didn't survive in my system. ------------- Jon https://www.youtube.com/channel/UC6y_EzjI_ljbIwf2n5uNzTw" rel="nofollow - What I've been doing... |

I do not want to divert this thread but as a newly paid member of WMAS I was interested if there was any direct relationship with WMAS and SeaScope. Also, what membership benefits are there in belonging to this society. I wanted to participate both in the wonderful learning resources of this WMAS sponsored forum and to contribute whatever I could, howbeit small, even with dues. I would be happy to receive a response even if it is a PM. Please feel free to move or delete my postings if it is thought that they do not belong to the proper thread or is offensive in any way as I am only trying to learn. ------------- Abandon hope, all ye who enter here. - Dante Riverton, Utah |

I was wondering the same thing.
Maybe it's because I made a plug so he wanted to make a plug? Or maybe it's because SeaScope has been a great influence on the hobby. SeaScope introduced the WMAS to http://www.garf.org - LeRoy Headlee/GARF and introduced the world to the NNR/Plenum technique of Dr. Jaubert. Or maybe it's because of something special coming up for WMAS members only. Or....  ------------- Reefkeeping Tips, & quick, easy setup tricks: www.utahreefs.com/forum/forum_posts.asp?TID=9244 Pay it forward - become a paid WMAS member

BrokeCurmudeon, I wasn't ignoring you, I didn't see the recent posts on this thread until now, sorry. Okay so to answer your question, yes it is related to members only (as Mark said in the post before this). So what is the connection you ask???? I'm not going to say. Not yet. But in a couple of weeks I will. So make sure you are a paid member (which you are), because in two weeks I'll tell all the members. If you are't receiving emails from me at the utahreefs account then let me know so I can add you to our mailing list. Until then, let the suspense build...... Adam

SUSPENSE! Like that? Now I'm curious too. Just glad I'm a paid member.
Now back to the topic. I have my refugium lighting on only when the aquarium lights are off. OK, not only, because I'm too lazy to fix all the timers just right, but mostly, only, when then the aquarium lights are off. I have been doing a lot of research lately on my planted freshwater tank and find that more hours of light than a normall day does not induce plants to grow more. In fact they need darkness so that they can respire, (exhale from a long days inhale I guess). I don't know if this applies to Algea, but I have a stong suspicion that it does at least to most Macro Algae. If anyone knows different I would be glad to change my mind on algea. (But not plants.) |
Thus I think that the Macro Algae in my sump needs the lights off during the day in order for it to grow and do it's job removing nutrients from the water.Posted By: Mark Peterson

| Wasn't there a post a while back where someone left their refug. light on all the time. he said it worked great. Don't remeber who or where he posted. I know some plants need darkness while some don't. Take Alaska for example. It's probably the same with algae some need darkness while other don't. I keep my refug. light on for about 14 hours at night. Just haven't experimented with anything else it just works good for me they grow and are a nice dark green. I think the only way to reach a sucessful conclusion is to do some research, but IMO not worth the effort. Hey suzy wanna try a phyto culture with 24/7 lighting? |

I have done that, left the light on all night over my phyto culture. It grew more phyto but I don't have the heart to leave it on 24/7. It just stresses me too much  ------------- Reefkeeping Tips, & quick, easy setup tricks: www.utahreefs.com/forum/forum_posts.asp?TID=9244 Pay it forward - become a paid WMAS member

Hold on, I have to go read the post again to see what we are talking about.... Ah yes, I got it. Well it isn't for paid members anymore. The presidency decided to make the June 17 meeting open to the public. We will be hosting Dr. Hovanec the head scientist for Marineland, and he is also the Editor for SeaScope. This is a great opportunity to ask him all your SeaScope questions, and you can also visit with him during the members only barbecue next Saturday. Hope that makes sense.
