Unfortunately, it was a disaster from start to finish. The solution seemed completely off—readings were inconsistent and wildly inaccurate compared to my previous trusted brand. This caused unnecessary stress and wasted time as I tried to figure out if my aquarium's pH levels were actually safe. To make matters worse, the customer care experience was beyond disappointing. When I contacted Labnox to report the issue, the executive was dismissive and unhelpful. Instead of offering a solution, they blamed me for "improper use," even though I followed the instructions perfectly. Their tone was condescending, and they refused to issue a replacement or refund. If you care about accuracy or decent customer service, steer clear of this product. It's not worth the frustration or the money. ## Frequently Bought Together - Labnox® Universal indicator solution pH 3.0-11.0 | pH testing solution 500 ml - Labnox® ORP indicator solution Anti-oxidant Drop For Water Testing | Orp testing solution | 500 ml - Konvio Neer Imported Tds Meter, Total Dissolved Solids Meter, Water Quality Tester, Ppm Tester For Water Testing - White --- ## 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.ph/products/491629701-universal-indicator-solution-ph-3-0-11-0-ph-testing](https://www.desertcart.ph/products/491629701-universal-indicator-solution-ph-3-0-11-0-ph-testing) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-05-22*
