Dimensions: W3.6xL35 cm The Dymax Stainless Steel Co2 diffuser features a unique ceramic refinement process. Its quartz plate ensures an excellent ultra-fine effect and a high dissolution rate, effectively dispersing a continuous flow of carbon dioxide into minuscule bubbles. These tiny bubbles create a significantly greater surface-area-to-volume ratio compared to larger bubbles, facilitating the gas's diffusion into water.Expires on 05 Jun 2026

Reef Builder effectively increases carbonate alkalinity (KH) without causing an immediate change in pH levels. With consistent use over time, it tends to stabilize around pH 8.3. When used according to the guidelines, Reef Builder will not reduce levels of calcium, magnesium, or strontium, which typically precipitate as alkalinity rises. KEY FEATURES: Enhances carbonate alkalinity (KH) with little effect on pH A unique combination of carbonate sources that won't lower pH, unlike other bicarbonate alternatives Will not diminish calcium, magnesium, or strontium levels DIRECTIONS: Beginner Administer 3g (1/2 level teaspoon) for every 150L (40 US gallons) two times a week. Mix in at least 250mL (1 cup) of freshwater. Monitor alkalinity every two weeks and modify the dosage or frequency as needed. For accurate measurements, utilize the Seachem Digital Spoon Scale. Advanced Measure alkalinity, then adhere to the dosage regimen outlined above until alkalinity reaches 3-6 meq/L (8-17 dKH). Each 3 g/150 L will increase alkalinity by approximately 0.25 meq/L. You can adjust the quantity or frequency, but do not exceed 12 g/150 L per day. After that, use as necessary to sustain alkalinity.Expires on 03 Feb 2030

Purigen is an exceptional synthetic adsorbent that stands out from other filtration products on the market. Unlike a blend of ion exchangers or traditional adsorbents, it is a distinctive macro-porous synthetic polymer that effectively eliminates both soluble and insoluble impurities from water at a rate and capacity that surpasses all other competing products by more than 500%. Purigen effectively manages ammonia, nitrites, and nitrates by removing nitrogenous organic waste, preventing the release of these harmful substances. KEY FEATURES: Outstanding organic removal capacity Enhanced capacity due to its extensive surface area; features both spherical and macroreticular structures Aids in controlling ammonia/nitrite/nitrate levels Color changes as it depletes; can be easily regenerated DIRECTIONS: Rinse thoroughly before use. Employ a fine mesh filter bag (180 microns or less) such as Seachem's The Bag. For optimal results, position Purigen to maximize water flow through it. It can be utilized in canister filters, media chambers, box filters, or any high flow section of a trickle filter. Each 250mL can treat up to 1,000L (250 US gallons) for a duration of up to six months. Depletion is indicated by a noticeable change in the color of the beads to a dark brown or black.Expires on 01 Jul 2030
