If you have a very large system or very little flow, you may want to wait 1-2 hours. You are safe to re-dose at that point as long as you have not changed more than 0.2 in pH, which is the maximum we recommend changing within a 24 hour period to reduce fish stress.

Many years ago this was labeled for ponds **Q: This should be fine for a Brackish tank?** A: You can use it however the KH of a brackish tank might prevent you from lowering the ph. Please contact API at 1-800-847-0659 and we can help. **Q: does this come with both ph up and down? Or just one of the two?** A: Just one bottle,ph up! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good *by R***L on 18 August 2018* Good ### ⭐⭐⭐⭐⭐ Review *by M***R on 12 September 2023* Love the size that should get me longer than the small dripper we all get in the first water treatment kit. ### ⭐⭐⭐⭐⭐ Review *by M***N on 27 January 2024* Excellent and I recommend it ## Frequently Bought Together - API pH UP Freshwater Aquarium Water pH Raising Solution for fish,4-Ounce Bottle, Brown - API TAP WATER CONDITIONER Aquarium Water Conditioner 16-Ounce Bottle - API STRESS COAT Aquarium Water Conditioner 16-Ounce Bottle --- ## 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.dk/products/77316645-api-ph-up-aquarium-ph-adjuster-4-ounce](https://www.desertcart.dk/products/77316645-api-ph-up-aquarium-ph-adjuster-4-ounce) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-04-25*
