What I have learned about cucumbers seems a good place to start and I am having them added to my dinner salad.
Actinopyga and Holothuria move through the sand and as they do so they ingest and digest any algae, detritus and attached bacteria, which provide them with nutrition. Cucumbers over 6 inches should never be maintained (will only go with a very small one or not at all) nor a medusa worm (synapta sp. Sea cucumber) both are toxic and can poison an aquarium if injured or sucked against a power head. Small sea cucumbers present no danger (Delbeek&Sprung 2007). What I understand is that they are not deep burrowing and seem to be ideal sand sifting cleaner in our refug.
I think in this situation what they bring to the table (no pun intended) out weights the loss of any microfauna at the surface level or our substraight
If I do get growth of Caulerpa on the Cheato side and I cannot remove it with out to much trouble I will just take out the Cheato sell it to my LFS and go with straight Caulerpa (Columbus took a chance). Can’t let gathering water parameter info become the focus of our refug.
And lastly IMO everything in this hobby requires work
Good information, how come you didn't post that in my DSB question thread? Got anymore DSB dwellers that you are keeping hidden up those deep sleeves of yours?
Sounds like you have the Caulepra and chaeto issue under control. And I agree, nutrient export should be/is the focus of our refugium. Gathering water parameter info while interesting will have to be secondary ~ not sure that it would provide "truly scientific data" anyway since we have no controls, repeatability, etc. But the data will be interesting none the less, and may spur on further discussion/modification.
And I agree, everything requires work ~ but obviously we enjoy it, or we wouldn't be doing it would we.
