Okay so i had gotten a used reverse osmosis system last year an since i do not have a reef tank i never set it up. Since i plan on setting a tank up soon i decided to install it today. Got everything up and running but i have one question that is haunting me. How do you know which outlet is for the clean water and which is for the waste? My system is not marked and i cannot find any info on it online. I am guessing the side which has the most flow which is how i have it connected now. Is there any other way of knowing for sure? Im going to order a test kit anyway so i guess thats one way of knowing. Anyone know a good test kit?
