A lot of planted aquariums love to use R O water. It gives a good base line for the water to grow plants also don't need water conditioner
What would you do with a RO system for freshwater tank?
see pics for size reference (note bolbitis and ranunculus pictured is already sold)
mixed moss - 2.00 per golfball - 7 available - I believe it
I will get a ray someday.... anyway... good luck!
