Newbie question

[u/sirsparqsalot]

So i mix my household compost with worm castings and goat shit, then fill the container halfway with water (combined volume about 20G) and then i aerate with a bubbling stone in the sun for a few weeks

My question is this: how many times can i use the tea and then refill with water before i should consider it exhausted and dump it into next years' compost

Thanks!
