Hahahahaha

How much water can these thing give u!

It would take forever just to fill up ur tank.....

Imagine a 4 ft tank will take at least ....i thk ......about 4 hour.......
hahahahahah

Correct me if u done it in a faster time....

But true, our tap water is killing our fish and plant...

I'm using RO water as well for my tank.... took me around 1 hour ++ for a 1.5ft tank........darn long.......

With these water, u have a better water quality.....but of course lack of certain mineral.... sign.....
