Small fridge..

[almost]

I know it sounds like a very stupid idea.. but many good reef supplements needs to be refrigerate after opening (vitamins, live phytoplankton, etc). So all those products can not be used with Ghl dosing pumps. A small fridge (to hold 3-4 bottles of 250 ml each) with opening for the air tube would be a solution for dosing those products.

Why you don't by a little fridge an do smal holes in it maybee 4.
Put Screws in it. Screws is not the right word i mean Hose Screws .
Sorry my Englisch is under all pig i know.
So you can fix the hose from Dosing Unit to the Fridge Output Screws.

I think that will be a cool Idea.

Because of the volume.

To feed frozen food, you need 1-1.5lt volume, the little fridges are something like 30lt. No space to put it + lot of waste energy (W)
