frozen food

I always thaw my food in a cup of tank water. No worry of introducing chemincals from my tap that way.
 
I never use tank water to thaw frozen food.
but,, that is because I feed several tanks.

I use a small tupperware bowl with lid and float the bowl in a tank.

the water slowly melts the food.

i can they use utensils like spoons to take the food and deliver it tothe tank.

I try to avoid cross contamination using this method. I wash the bowl out with tap water and keep it in the freezer or fridge till the next use.
 
I have a strainer into which I put frozen food and then thaw and rinse it before feeding.
