It is very small and sleek but does not perform at all. We have a 127 gal reef tank (we are not new to this!) and hoped to use this for our auto refill. We also have a 54 gal reef tank and were searching for top-off systems for both. Everything connected smoothly and easily, but all the unit did was flash the lights and beep incessantly. No amount of changing location, tubing height, tubing distance, depth, pumps, monitor, etc...NOTHING made this perform as it should. In EITHER tank. We tested this thing for hours and were never able to successfully have it fill anything. Very disappointed. ### ⭐⭐⭐⭐ 👍🏾 *by K***D on Reviewed in the United States on December 28, 2019* solid 3 so far but I'll give it 4 based what it offers for the cost. I posted a video review. ### ⭐ Probably works. *by D***S on Reviewed in the United States on February 21, 2020* Probably works well if they could send it with all the parts . After two returns I gave up. --- ## 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.gr/products/107272956-epttech-aquarium-marine-reef-fish-tank-automatic-auto-top-off](https://www.desertcart.gr/products/107272956-epttech-aquarium-marine-reef-fish-tank-automatic-auto-top-off) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-05-30*
