- Not sure if your aquarium is ready for your fish or shrimps? - Not sure why your fishes are dying all of the sudden? I can do aquarium water testing through drop testing methods which is very accurate. ✅ Ammonia (Extremely toxic to fish if high) ✅ Nitrite (Blocks oxygen in fish blood if high) ✅ Nitrate (Algae & poor growth if high) ✅ pH (Sudden change can shock or kill fish if high) ✅ KH (Prevents dangerous pH crashes) ✅ GH (Important for fish health & shrimp molting) ✅ TDS (Overall water quality & mineral buildup) Early testing prevents fish loss, algae problems, and water crashes. Price : 45sr for the whole test. Location : Al Aqrabiah, Khobar. You will need to bring at least 1 cup of water from your aquarium.
