Looks to be standard airline tubing, maybe a tab smaller.
But, I don't use the bag anymore... I sealed the bottom of the chiller with silicone, and I just pour the food in. I've been leaving the top off too, with a stirring stick there, and stir it when I think about it. If you mix the right amount of the Sodium Alginate powder with the home-blendid oysters, it will stay mixed and not need stirring for a week or two.
Is there a way to adapt this design to feed fish? Specifically, frozen foods two-three times a day. I have a 30g tank with a falco hawk and a dottyback, but I am interested in keeping seahorses(in a different tank of course).
Certainly... just add some cubes of frozen rotifers, etc. And blend the oysters less, so it will have larger particles.
Actually you might experiment with just adding the Sodium Alginate powder to just the cubes. Too light powder and the food separates; too much and it solidifies.
Cool!
Don't use the bags anymore... Jeez, I just bid on some on ebay not 5 minutes ago! Doesn't the food freeze without the bag and filter sock?
It could, but it could with the bags too. Keep the top open if it does, and/or keep it near the lights.
santamonica, I have a question...
I noticed in your picture that you have about 2 feet of tubing thats always full of food that stays out of the chiller until the next feeding. do you have a problem with the food in the tube spoiling? or does your peristaltic unit pump this food back to the bag in the chiller by running in reverse? I would like to feed about 1 ml/hr which is about the amount of food that will fit into 6" of 1/4" tubing. If I have 1 foot befor the pump wheel and one foot after it than the cold food leaving the chiller will sit in the tube for 4 feedings or if you set it to 1 ml/hr that would equate to 4 hours befor that food in the tube gets dosed. I would think that food starts to spoil in that time.
How do you prevent the above?
I applogize if this has been asked befor. BTW, just build my algae scrubber and so far so good. thanks in advance for your help!
The food just sits in the tube. Not the best situation, but until someone makes a chilled feeder device, it will have to do. Does not seem to hurt anything, except for adding extra nutrients.
another set of questions...
I noticed that you wrapped your lines due to the above... just curious if have you tested the temp of the food coming out of the feeding tube after it has stayed there? is it room temperature or slightly above?
where can I get Sodium Alginate powder and raw oysters? thanks again
Have not measured it. It has to help, but no idea how much.
Oyster or mussels are at your grocery.
Somewhere in this thread is a link for the powder. Many cooking supply sites will have it.
