Without dosing daily it's a little difficult. Not unachievable, just a little harder to dial in the correct dose.I was a huge believer in real ocean water water changes, but when the company I bought mine from changed the filter method and started adding synthetic, I changed after noticing the difference. So I went with Kent first, then secheam. Both are ok products but harder to dose on a daily basis. Easy to use when correcting either cal or alk, but daily dosing wasn't much fun. Next I tried bulkreef. This was much more to my liking but lacked the minor trace elements. Then I discovered esv!!!!! My corals started gaining colors that I hadn't seen since I used real ocean water to do my water changes with to replace my elements. It was so nice adding a dosing pump to dose esv for me. And after about three weeks on my tank, I achieved ionic balance. Now my buddy's tank, it took about 2 months to dial in. (He dosed mon-fri when he was in his office) I would test his water weekly and make adjustments accordingly, but took longer to make up for the two day gap in dosing. Took a while to get it right, but never could achieve ionic balance till he got a doser.So yes I absolutely recommend esv ### ⭐⭐⭐⭐⭐ Best system I’ve ever used! I’d never use anything else! *by J***Y on July 14, 2020* Very easy to dose and monitor levels!! Great value- is never use anything else! ## Frequently Bought Together - ESV B-Ionic Calcium Buffer System, 2-part Calcium and Alkalinity Maintenance Kit for Salt Water Coral Reef Aquarium, 2-Gallon - ESV Aquatics B-Ionic Magnesium for Coral Reef Salt Water Aquariums, 1 Gallon - Instant Ocean Reef Crystals Reef Salt, Formulated Specifically For Reef Fish Tank Aquariums --- ## 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.com.br/products/4815127-esv-b-ionic-calcium-buffer-system-2-part-calcium-alkalinity](https://www.desertcart.com.br/products/4815127-esv-b-ionic-calcium-buffer-system-2-part-calcium-alkalinity) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-05-16*
