Hanna Checker PHOSPHOROUS   Ultra Low-Range (0 to 200 ppb) Checker® bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits have limited accuracy and resolution since they rely upon the human eye to discern differences in color. Professional instrumentation incorporates a light source such as an LED or tungsten lamp with a filter and a light sensing detector to precisely determine ion concentration. Professional instrumentation offers greater resolution and accuracy but can cost hundreds of dollars. The Hanna Phosphorus Ultra Low-Range Checker® uses a fixed wavelength LED and silicon photo detector to provide the accuracy of professional instrumentation at the affordable price of a chemical test kit.

Hanna Checker MAGNESIUM

Handheld Checker for Marine Magnesium.  Magnesium is the third most abundant ion in seawater, surpassed only by sodium and chloride. Its abundance is critical in the formation of weak ion pairs with carbonate ions. This allows calcium and carbonate ions to be available for uptake by corals and invertebrates.  Low levels of magnesium lead to low or unstable levels of calcium and alkalinity. Signs of low magnesium levels include precipitation of calcium as insoluble calcium carbonate and impaired inhabitant growth and health. The HI783 Marine Magnesium Checker HC is a handheld colorimeter that uses the Beer- Lambert principle to determine the concentration of magnesium colorimetrically. The HI783 is designed specifically to measure magnesium levels in a saltwater aquarium or in marine biology applications. The 1000 to 1800 ppm range is ideal for coral/fish or fish-only aquarium maintenance.

Prevent rock-slides in your aquarium - this construction epoxy is designed specifically for bonding rocks and corals in a reef aquarium and cures underwater to the colour of coralline algae.

Aquascape is a two-part epoxy putty that has been specially developed by D-D for use in salt water and freshwater aquariums and other underwater applications.

Uses in the Aquarium: In the marine aquarium it is ideal for bonding together live rock to form complicated structures and avoiding rock falls caused by turbo snails, sea urchins and strong current flow, for preparing coral frags and for creating clam bases to prevent them being attacked and ultimately killed by bristle worms. In addition it can be used to repair leaky pipe work, broken equipment or for bonding items to the aquarium glass.

Aquascape has been developed to be stickier than most epoxies so that it bonds easier to wet substrates and the purple version has been formulated to dry under water to the colour of coralline algae. This makes it initially more natural within a marine aquarium during the period before being encrusted with true coralline algae. Note however that when cured out of the water the colour will be darker representing the deep red coralline algae colour.

CorAffix™ Cyanoacrylate Adhesive CorAffix is an ethyl cyanoacrylate bonding compound with viscosity similar to honey.

Use it for attaching stony corals, gorgonians, and other sessile invertebrates in natural positions on the live rock in aquariums.

Also for attaching coral “frags” in coral culturing. Use with AquaStik™ to attach larger coral heads.

HOW TO USE:

1. First put freshly mixed AquaStik on live rock.

2. Push the coral base into the AquaStik and then remove the coral, leaving the impression of the coral base in the AquaStik left in place on the live rock.

3. Allow the AquaStik to harden for 20 minutes.

4. Next put CorAffix on the coral base and press it into the impression made in the AquaStik, forming a secure bond in 20 seconds.
