I have Selco-the concentrated version-lake a thick orange paste. I only used it sparingly as have had dificulty getting it to soak into foods. Fouls water with cloud.
I drip two or three drops on a cube of Marine Cuisine or Emerald Entree as their dethawing. I think it's great stuff for a reef tank. If those all those HUFA's don't make it into my fishs' stomachs, then I feel like that 'cloud' settles out to feed my fan worms and infauna.
I'm with PO on this, but I mix Selcon with my Formula1 and 2.
I also feed brine shrimp to my tanks on occassion. Brine shrimp are poor in nutrional value, so I also add some Selcon to a container of brine shrimp to gut load them with the product for a good half hour. Then I drain the liquid and ring the dinner bell!
I mix it into my homemade food and also allow it to soak into nori before feeding it.... its been shown that HUFA/PUFAs (contained in selco) are great at preventing and fixing lateral line disease in tangs and generally improving the health of fish.
Selco/Selcon is great stuff. Mixed into my homemade frozen foods and Nori is squirted with it. Selcon is much more concentrated than the average hobbiest needs. Just use Selco.
A fellow reef keeper is kind enough to refill my Selco bottle from his selcon as he'll never be able to use it all up. He dilutes it to something like 10:1 or 20:1 (I'm guessing here) and that is still so much more potent than the standard Selco. Fills the Selco bottle up with RO/DI and he just adds a few drops of Selcon to it.
This has been debated back and forth a few times, but suggest to the LFS to keep his Selco/Selcon in the fridge. At worst it won't harm it, at best it will greatly extend its useful life.
Get Selco. You get alot more for your money. My fish chop on the food so quickly, that the coated on the frozen good really go into their stomach. I also use a syrine and pump it into shrimp or fish and then feed it to my Anemone.
I didn't know selcom and zoecon are the same. Oh well. I rotate and always soak all foods in either selcon, zoe, or zoecon. And occasionally I soak the food in a little garlic. Works for me.
