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 *by A***R on Reviewed in the United States on May 31, 2017* 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 ### ⭐⭐⭐⭐⭐ I highly recommend this tank *by J*** on Reviewed in the United States on July 31, 2015* 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. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/10707624-7-5-gallon-acrylic-auto-top-off-container-for-aquarium](https://www.desertcart.co.th/products/10707624-7-5-gallon-acrylic-auto-top-off-container-for-aquarium) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-23*
