7.5 Gallon Acrylic Auto Top Off Container for Aquarium Reef Tank ReefCreators.com

We paired our ATO container with the TUNZE 3155 ATO. Our first impression was addressed with a simple note in the box. What appears to be sloppy acrylic welds on the inside of the container, in fact was double insurance. Additional glue to prevent any leaks. Protective film is on the Acrylic when shipped, to prevent scratching. We added some furniture felt pads to the bottom of our container. We have a hard tile surface, and didn't want it to scratch. Also reduces any noise generated when the ATO pump is running. The transparent front allows you to see how much water is remaining. We marked each gallon using a label maker.A suggestion: Perhaps this is something that can be incorporated in future designs? Not a deal breaker for us. Just nice to have, when measuring the amount of top off water, and amount of Kalk to add.Oh and it is very easy to clean out. The door flap on top is large enough to fit my hand inside to wipe everything clean.

Looks great. The holes on top could be bigger. A bit difficult to add water without a funnel. Also you will have to use a very small pump in order to fit into tank... other than satsfied with purchase

Very handy and large capacity tank. I have been using this for a few months now and it has made life a lot easier. This cube fit perfectly on the bottom shelf of my Biocube 29 stand and in combination with an auto-top-off unit, I only have to fill it every couple of weeks. The only challenge I see will be how to clean it. It has developed a residue that I will need to clean and with the limited opening this may prove a challenge. Regardless, I highly recommend this tank.

I waited 2 weeks for it (not a big deal) and I couldn't be happier, it arrived with out a scratch nor cracked or anything looks really nice next to my 55 gallons reef tank and has not leaks whatsoever. With my setup, this 7.5 gallons water reservoir needs to be refill only once a week... It took the headache away, I went from pouring a gallon a day into my tank manually to this beauty. It worth every penny!

I've been patiently waiting for this to arrive, and I'm beyond disappointed. There's an active leak at the bottom seam. Overall, I think they could do a much better job with the seams. They appear to be weak all around with very little sealing.

My only complaint was it was not Prime and took about 10 days to get it. The unit is strong and holds just the right amount of top off water for my RedSea Reefer 350

Perfect with my Red Sea Max 250.

Cheap, not worth $120, can be made for a fraction of the cost with parts from Amazon.
