Hi everyone!\r\n\r\nI am new to this site, and just got back into SW. I had tanks from the 1970's into the 80's (things ALOT different then). So I have my 65 gallon set up with a 100 gallon I am going to get going as soon as I can get the $ for the live rock, etc. Also have a 20 gallon that is basically my QT/macro grower tank. \r\n\r\nWhat I wanted to ask was regarding the output on my RO unit. It is a Kent RO 60 gpd. Should there be approx three times as much waste water coming out as good water? I knew that it would make ALOT of waster water, but is that much normal?? \r\n\r\nThanks!!
