Alright my current ATO set up is well right now the poor mans way.
I have my RKL just have a pump turn on and off at a specific time for a certain amount of time, it sorta does the job.

i know i know...get the RKL float switch kit.. im working on it.

I have a 5.5g tank sitting next to my sump where i hold my ATO water.
Now i wanna streamline this more, so i dont have to fill the tank up, i wanna cut that out all together.

whats my best option? use something like this
