BlueLine Tsunami AT1 Auto Top Off System

Very very very hard to set levels.

Very easy to setup and use. Includes a simple diagram to setup. This purchase works best if you can provide your own reservoir sump, pump and plumbing. This was perfect for me as I had these things laying around the house.I gave it four stars for two reasons. First, it would be nice if it had magnetic holders instead of suction cups. But the suction cups isn't too bad either. Second, it would be nice if it included way to mount holes or brackets to mount the AT1 under the stand or something. But getting a cable mounting base and a zip tie works too.Comparing the price versus other options, you really cannot beat the price for what you are getting out of this unit. I would recommend this product.

I got two and a half years out of it before it stopped working so I guess for the money can't complain

This was purchased to replace another crappy top off system. This one works without any issues. I’d recommend it over others.

I did not know I still hade to buy the pumpDisappointed

I bought this for my sump as part of my 90 gallon reef system. It was very easy to set up, and it works perfectly. The suction cups work, but I would recommend modifying it with a magnet to be on the safe side.

Owned one in the past, and would own another one in the future. Simplicity is best for reliability. Used it for a salt water 29 gallon nanocube as a topoff

Easy to install, simple, but works great and reliable! Cost versus how good it works, makes this product well worth consideration for the money.
