Tunze osmolator top off is the best system you can buy. Well worth the price, comes with its own pump and has 2 different technologies working flawlessly to protect your tank and home from a flood.

This is my second unit i'm ordering, first one was about 2 years ago. This is for a second setup, the first one is doing great. The one problem with these is the power plug. After sometime it becomes corroded and you get strange errors like overfill alarm wont stop. But if you have any problem the first thing to do is take off the 2 screws and clean the port and the plug. I cut a nail file down to about 1/8" to clean the port, and just a drill bit to scrape the plug inside. worked great and im good for another 6 months at least. At some point i'll just solder the wires and never deal with it again.

You do get what you pay for... Keeps my water level constant. Love the optical sensor they use on this system. No brainier to install. Now all I need is to make something to hide the top off container...

I recently upgraded my 60 gallon reef tank to a 180 gallon. With my 60 I just topped off the old fashioned way but that was getting to be a chore with the new tank. I was on board with purchasing an auto top off but had serious concerns about failure...particularly in the on position. Virtually every other ato product out there was peppered with negative reviews regarding failure. We have thousands invested in the tank so it was worth it to spring for the osmolator. Piece of mind and very easy to setup. Skimmer works a lot better to.

Good Top Off Bad Instructions By Mike on 3/25/2013

The instructions on this top off could be WAY easier to understand if it didn't have 6 different languages on each page. Also, it should also state in there that you need to soak the opitcal sensor in soapy water and gently wipe off the polishing residue on the sensor before installation, also there is a dial on the inside of the controller that you need to set depending on the size of the aquarium or sump that you place the sensor in, the dial basically sets the dosing the pump pumps water into the tank/sump. A little better instructioni pamphlet would give this product 5 stars!

I have this running on my aquarium and it is spot on and fail proof . the back up plunger has not been activated Probably because the top off system works so efficient, Great product recommend to anyone who is tired of adjusting or just having other systems that fail.
