Copper – a treatment for many parasitic infections – must be monitored in an aquarium or a pond. The copper level can drop too low for the treatment to be effective, or can increase to a point that is detrimental to fish health. Copper is likely even present in your tap water. The API® COPPER TEST KIT allows you to easily and accurately monitor copper levels to maintain copper-based fish treatments at therapeutic levels, and tests copper levels from 0 to 4 ppm. The kit measures both free and chelated copper, and is for use in fresh and saltwater aquariums, or with ponds. Contains 90 test and includes 1 test bottle, easy-to-ready instructions, glass test tube and color chart.Best Before Guarantee: 28/11/2026

API® TROPICAL FLAKES is designed specifically for tropical community fish such as Angelfish, Tetras, and Barbs, and contains a unique, nutritionally-enhanced protein to ensure easy uptake of nutrients for maximum absorption. Fish more readily use the nutrients in our high-quality formula, and as a result, release up to 30% less ammonia than the leading competitor for cleaner, clearer water. API TROPICAL FLAKES may be used as an equally nutritious, alternative tropical food to API TROPICAL PELLETS, depending on your fish’s preference. As an example, larger fish may prefer pellets to flakes because of their density, compared with smaller fish that may more easily consume the light texture of flakes. Feed twice a day. Sprinkle a few flakes per fish, only as much as they can consume within three minutes. Best Before Guarantee: 28/07/2025

Calcium is one of the most important elements in a reef aquarium.

Makes it easy to monitor the nitrite level in fresh and marine water Nitrite (NO2) is among the most toxic substances for fish in aquariums. It can enrich in the water in case of insufficient biological filtration. The sera NO2-Test allows monitoring the nitrite level in fresh and marine water easily and reliably. We recommend using sera bio nitrivec (freshwater), sera marin bio reefclear (marine water) or sera pond bio nitrivec (pond) in case of slightly elevated nitrite levels. In case of severe nitrite problems, sera Nitrite-minus quickly provide help. Sufficient for approx. 75 measurements.
