Auto top off unit

[Flyboy450r]

So I have a 29gallon tank and a ten gallon sump and I have evaporation issue like I cant believe. Ive been looking around and have a few ideas but Im curious what everyone else thinks I should do or what you guys can suggest. I was thinking about hooking it up to a ro unit and just putting it on a float only issue is my closest pipe is 10-15 from my tank. Dont really have space for a second tank. Maybe a bucket next to it with a pump? Any suggestions will help Thanks Mike

I use the reef fanatic unit with a aqua lifter pump and a 5 gallon bucket for my top off and it works perfect!!!!! Couldn't be happier with reef fanatic, their floats are very sensitive. I glued my floats to the smallest mag floats available(like 8 bucks apeice) so I could move them around easy and not worry about the suction cups falling off. Make sure your pump is below the highest point of your line to your tank and do not have the end of line submerged.
