Hanna HI774-25 Phosphate ULR Reagents Marine Water

Hanna HI774-25 Phosphate ULR Reagents Marine Water

Hanna HI774-25 Phosphate ULR Reagents Marine Water are refill reagents for measuring phosphate levels in saltwater with Hanna's handheld Phosphate ULR ppm Colorimeter HI774 and the Marine Master HI97105 Multiparameter Photometer. They are made for reef keepers and marine aquarists who already own one of these Hanna meters and want to keep testing. Each pack contains 25 packets of reagent.

Key Benefits

• Phosphate Ultra Low Range (ULR) chemistry for tracking the low phosphate levels marine hobbyists aim to keep in their systems.
• Formulated specifically for marine water, so you can use it in reef tanks, fish-only saltwater systems and marine holding systems.
• Refill pack for two Hanna instruments, so one reagent covers whichever compatible meter you own.
• Pairs with the easy-to-use, handheld HI774 Checker HC for quick phosphate checks at the tank.
• Regular testing gives you hard numbers to act on when you adjust feeding, filtration, water changes or phosphate-removal media.

How to Use

Use these reagent packets with your Hanna HI774 Phosphate ULR Checker HC or HI97105 Marine Master photometer. Follow the testing procedure in your meter's instructions to take a phosphate reading from your marine water sample.

Frequently Asked Questions

Which meters do the HI774-25 reagents work with?
They are refills for the Hanna Phosphate ULR ppm Colorimeter HI774 (Checker HC – Marine Water) and the Hanna Marine Master HI97105 Multiparameter Photometer.

What does "ULR" mean?
ULR stands for Ultra Low Range. The reagent is designed for measuring the very low phosphate levels that marine aquarists usually try to keep.

Can I use these reagents in a freshwater aquarium or pond?
These reagents are labelled for marine water. If you need to test freshwater or a pond, choose a Hanna reagent intended for that application.

How many packets come in a pack?
Each HI774-25 pack contains 25 packets of reagent.

Why should South African reef keepers test phosphate regularly?
Phosphate can build up from feeding and from the source water. Regular readings let you see how your tank is trending, so you can adjust feeding, water changes or filtration with confidence.

Does this pack include a meter?
No. The HI774-25 is a reagent refill only. You need a compatible Hanna HI774 or HI97105 instrument to take readings.
