Your reading is your ph in your soil **Q: Can I use this in a hot tub** A: Why not just buy the correct product at a pool supply store (or Lowe’s, Home Depot, etc)? **Q: Hi.. Hydroponic newbie! is this considered "organic" compared to other ph up/down products sold? Thanks so much.** A: The ingredients are potassium carbonate and phosphoric acid. I couldn't tell you anything beyond that. Sorry ## Customer Reviews ### ⭐⭐⭐⭐⭐ I was skeptical… *by P***9 on Reviewed in the United States on 29 April 2023* After reading the reviews I was skeptical but when it arrived and I treated the water that started with a ph of 9.3 and put a few drops in it dropped to 4.13. It worked great!!! Seals were good when opening looked brand new and worked as it should! ### ⭐⭐⭐⭐⭐ A little goes a long way! *by A***W on Reviewed in the United States on 26 June 2023* I’ll start by saying I’m using this on water that’s already been through a 4 stage reverse osmosis system. That being said I’m already pretty close to the desired parameters.I’m making my water in gallon jugs and using a small syringe to add the solution.I needed to lower my PH just one full number and all it took was less than 3 ml of solution to do it. This should last quite a long time if it continues to be this efficient.So far I’m pretty happy with it. The bottles are pretty small but as little as it takes to adjust your levels it doesn’t really matter. ### ⭐⭐⭐⭐⭐ needs a dripper but otherwise easy use and fast *by C***O on Reviewed in the United States on 15 June 2023* quick and easy solutions, for a gallon at a time all it takes is a few drops. ## Frequently Bought Together - Atlas Scientific pH Up and Down 250ml (8oz) - VIVOSUN Digital pH and TDS Meter Kits, 0.01pH High Accuracy Pen Type pH Meter ± 2% Readout Accuracy 3-in-1 TDS EC Temperature Meter for Hydroponics, Pool and Aquarium, Yellow Blue, UL Certified - General Hydroponics CALiMAGic 1-0-0, Concentrated Blend of Calcium & Magnesium, Secondary Nutrient Deficiencies Helps Prevent Blossom End Rot & Tip Burn, Clean, Soluble, 1-Quart --- ## 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.tn/products/238823893-atlas-scientific-ph-up-and-ph-down-control-test-kit](https://www.desertcart.tn/products/238823893-atlas-scientific-ph-up-and-ph-down-control-test-kit) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-07*
