I love your high level of success. Can you tell me about your walls? Are those dendros the result of spawning?

Thanks!
Well, I only know that the polyps on the walls originated from the yellow tubastrea at the right-hand side of the tank, about 7-8 months ago(it was alone at that time). I'm not sure it spawned, as at the same time it lost a number of polyps. I've read somewhere that it may be possible for the polyps to leave the colony when under stress.Just my 2c... Other opinions?

Did you add somenthing to the walls or did you just let it grow out neturally?

All natural, grown in a few months on bare glass.

Cool. It's just going to get better and better looking with time.

Taken from Advancedaquarist, sun corals are hermaphroditic and can also reproduce sexually and/or asexually by producing planulae larvae11/12, which they will also do in aquariums at times. These can drift around an aquarium until they eventually settle and develop into a new colony. So, don't be surprised if new colonies seem to spring up from nowhere in an aquarium containing a well cared for specimen. Like this.

Keeping food in circulation/suspension is one reason why I prefer no sump. Once you can just keep food in the display, you can just circulate it non-stop until the food is eaten. With a sump however, it eventually settles out.

@SantaMonica
I fully agree, when stopping the return pump the polyp extension extends longer after feeding. Strong current pumps are equally important, preferably alternating, to avoid deposits.

However, such a system needs a lot of filtering. how can it be done with acceptable aesthetics using only the display?

That's the filtering challenge. Check the advanced section for the scrubber thread, and lots of ideas there.

BTW many NPS are uni-directional feeders, especially deeper ones, and they orient themselves to only one direction of flow.

Here's the sun-powered AS on duty on my system, working together with a greatly oversized skimmer, macroalgae refugium, ozone and carbon/GFO reactor.

Sun power is great

Just a little water pump power, and you have great filtering.

Indeed . Actually this is one of the main drawbacks(other than size), it makes the day/night pH swings even larger. Also, for an SPS tank, when the sun peak intensity matches the tank lighting, I guess it may happen to compete on photosynthesis ingredients, like CO2, iron, etc. Any thoughts?

How do you keep the outside contaminants out of your reef? Neighbors spraying plants, etc etc etc. This would have my ocd running wild

True, contaminants are a real risk. Well, there's actually a detachable acryl panel covering the upper side of the scrubber(4mm thickness, similar to the fixed lower part). I have removed it for this picture because of the reflections.

Photoperiod is probably not a concern. Worst case the pH get up a little high, but 8.5 is not going to hurt anything.
