Randy's new 120 gallon Reef

[Randy Holmes-Farley]

The bulkhead connector is the path between the two cans, without any pumping, and the levels approximately match. Water enters one can, and is sent out to the tanks from the other, forcing it through the bulkhead between cans.

The only update is that the green slimer SPS coral (not sure of the species) on the far right in the picture started to RTN by contacting other corals,so I fragged it.

Heres your old thread on your yellow tang. Lots of people have posted since then. Did you see it lately? Paricularly intersting is one member said he turned his ozone off and his yellow tangs fin damage whent away.

Hows your yellow tang doing today?

[Randy Holmes-Farley]

He's about the same. I haven't looked at that thread in a long time. Thanks.

I read a project by some univeristy on reef regrowth (sorry can not find it yet)

They used "Bali Slimer" to regrow over dead coral skeleton and it grew unusually fast. By attaching small pieces to the ends of dead coral bones, the Bali Slimer over grew the dead areas at an unusually high rate.

I tried the same thing and it worked pretty well.

I also noticed that some areas of the Slimer would start to turn black or overgrow with algae. I just "scraped" them clean down to white skeleton and the live tissue overgrew that area pretty rapidly as well.

Greetings Randy - I stumbled across this thread and note the photo shows your tanks has sand that appears more for show than function. Are you basically running a "bare bottom" with rock for filtration and the sand for decoration? I ask only because one of your articles on NO3 control mentions a deep sand bed as an option yet I am reading the long term issues with SO4 in sand pockets are a problem. Thx...

[Randy Holmes-Farley]

I have deep sand in two of my four refugia, but I don't think it does anything useful at the moment. The tank has sand only for show. I've never had hydrogen sulfide problems with sand, even when the sand bed was more than 10 years old. The bulk of the nutrient export is by macroalgae.

OMG !!! I need to faint !!! what a tank !

[Randy Holmes-Farley]

Thanks.

Randy - biochemically speaking, do you prefer the deep sand bed concept or the one you currently have. I am considering the same design as yours - sand for show.

[Randy Holmes-Farley]

When I've recently added refugia, the have not included sand.

Randy,

on one of the articles you mention that you have a canister in which you put the activated carbon and phosphate binder.
Can you please show a picture or a sketch where it's positioned in your sump system?
thanks

Both hoses of the cannister run over the top of the can lip and into the sump. It sits on the basement floor beside the sump.

[yraveh]

Oh... You New-Englanders have the luxury of a basement.
I am struggling to convert a wed/dry part of a sump into a refugia (for export purposes). for that I need to design a way/place for the carbon and for mechanical filtration by the floss.
All that need to fit in a small under-the aquarium space. so I was looking for a compact and simple idea.

[Randy Holmes-Farley]

Yes, basements are very handy. But you in Miami have some loctional advantages as well.

Randy – I presume you have a refugium in which the Macroalgae flourishes. In your experience have you noted a given value of surface area needed for algae support and NO3 export in contrast to overall tank volume? Basis of ? is that I’m near completion of a 200 g in wall unit and need to eval space requirements intrasump or external. Thx
