Easy to dose and affordable. Corals are responding well to the stability afforded. ### ⭐⭐⭐⭐⭐ Quality Alkalinity and Calcium *by J***S on March 14, 2024* This is my go to brand for quality Alkalinity and Calcium. The ingredients and quality consistency has been very good. The volume of product for the price is a great value compared to fish stores. This brand of 2 part has done wonders for my 5 year old reef tank! I will be back for more! ### ⭐⭐⭐⭐⭐ Its made of magic. *by A***N on July 14, 2015* Love this stuff. I put it in my 90 gallon reef tank every morning.Ok, I don't really, but I do it when I remember. The corals seem to love it. I asked them and they didn't respond, but that's because corals can't talk. If they COULD respond they'd tell me that they love this stuff, along with some critiques about my tank maintenance practices and personal hygiene.My fish seem indifferent and downright apathetic to it, but fish are stupid. Have you ever seen a fish with a college degree? No, not a dolphin - those are porpoises and I said fish. That's what I thought. They wouldn't know a good 2-part Calcium buffer product if it smacked them in the face.I don't know if I need this stuff really, but I like it. My tank is purpler and that is pretty. The way it makes a 10 second cloudy burst of chaos when part one is administered is fun, too, and I get to say things like "Oh no! There's been a terrible explosion and life as you know it is going to end! Quickly, find solace amidst the coral reef!" Stupid clownfish. They aren't even funny. --- ## 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.hr/products/8731328-esv-aquatics-b-ionic-calcium-buffer-system-2-part-calcium](https://www.desertcart.hr/products/8731328-esv-aquatics-b-ionic-calcium-buffer-system-2-part-calcium) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-16*
