Aquarium Advice FINatic
I'm finally going to spring for a ro/di filter. I only have a 20 gallon tank so I don't need one that makes 75 or 100 gallons a day. Maybe 25gpd or smaller. Any suggestions for an affordable unit ? Right now I do 5 gallon a week water changes and buy my salt water from my LFS. 5 bucks a week didn't sound to bad but even that small amount adds up over a year.
