Fluval sells some for filtration.  You can also use bags of active substrate in the tank.  This is common for Caridina shrimp tanks.

What is your PH now? How far do you need to shift it?  Adding some wood in the tank might be plenty.

My pH is at a 6.6-6.8vi just need peat moss for breeding

For this same species, I've been trying to hatch a spoonful of peat with eggs from a breeder, and have only gotten as far as 3 days post hatch survival. 

I'm feeding vinegar eels. First attempt I tried placing them in a new container with an eyedropper, bit gave them like 4 drops of vinegar eels a day. 2nd time I left them in the container they hatched in and gave them more like 2 vinegar eel drops per day, and changed 50% of the water after day 2 (unchlorinated). 

The hatching container is a glass pot about 2.5" high and 2" in diameter. 

What should I try next to improve survival?

My pH is probably 7.8.
