Aquaforest Strontium (50ml)

Description

***Aquaforest Strontium 10ml has no longer available***
Supplement containing highly concentrated strontium and barium. Strontium, after calcium and magnesium, is one of the most important elements needed for growth of hard corals. Strontium supports the formation of hard coral skeletal tissue and significantly improves the calcium absorption. It also supports the growth of soft corals. In a closed aquarium system, skimmer and filtration media remove strontium deposits from the water, therefore its supplementation is necessary. In order to ensure that the aquarium conditions are as close as possible to the natural ones, the preparation was enriched with the addition of barium, which is also present and significant in seawater. Thanks to the appropriate proportions, Strontium effectively complements the strontium and barium deficiencies in aquarium water and guarantees the perfect ratio of these elements. The recommended level of strontium in aquarium water is 6.00 – 10.00 mg/l (ppm).
Dosage: 1 drop per 100 l (27 US gal) of water daily. 1 ml of Strontium (~15 drops) in 100 l (27 US gal) of water raises the strontium level by 1,09 ppm.
It is important that each aquarium is different and the dosage depends on the coral cast and individual needs.

Aquaforest Strontium 50ml for Reef Tanks in Singapore

After calcium and magnesium, strontium is one of the elements stony corals draw on as they lay down skeleton, and this concentrated AF supplement also carries barium. We dose it in mature SPS and mixed reefs where rapid coral growth steadily depletes minor elements that a standard salt mix alone cannot keep topped up. The small 50ml format suits the modest nano and frag systems that are common in space-limited Singapore homes.

Strontium supports skeletal formation and improves calcium uptake, and it benefits soft corals too, but more is not better. We always test before chasing a number, since overdosing trace elements causes more grief than a mild shortfall. Add it slowly to high-flow areas and let your existing calcium and alkalinity routine stay the priority, with strontium as a refinement rather than a headline parameter in a closed system.
