Another Calcium Feeder Recipe
Ingredients:
1600 mL of plaster of paris (Dap brand from Home Depot)
800 mL of water
1 100g container of tetra color sinking goldfish granules
Tools needed:
A large plastic pitcher
A 1L measuring cup
3 ice cube trays
A stir stick
Mix the water with the plaster until completely smooth.
Add fish food and mix evenly.
Pour into the ice cube trays. Rattle to trays to remove air bubbles. Let sit in a dry place for 2 days. Once the trays are good and solid, twist to remove the blocks. If the blocks are crumbling or breaking, they are not dry enough yet. Once they are out, cure them in a dry place for five more days (or use a food dehydrator). Once cured, they can be vacuum packed for storage. Each feeder typically lasts two weeks.
*The calcium in these feeders will buffer water to help maintain a basic pH.
I am all ready to make this and I noticed the DAP PoP has silica in it, is this a problem?
