When used in conjunction with TRITON Lab ICP testing aquarists are now able to make targeted single element adjustments. Only TRITON delivers advanced aquarium husbandry with ease-of-use. For dosage information please check the DOSE tab of your ICP analysis.

The TRITON macro and trace element supplements range is supported by over a decade of scientific research into the chemistry of natural and closed system seawater.

Pack Size & Dosage

100 ml, at ten times concentration. TRITON now supply the Strontium macro element as a 100 ml bottle at ten times the strength of the old one-litre liquid, so one bottle does the work of the litre it replaced. This listing used to say 100 ml; the concentrate is the current format. The price on this page has not been changed to reflect it — ask us if you want it confirmed before ordering.

Ten times the strength means ten times the care. A dosing error that would have been minor with the old litre bottle is a tenfold error with this one. Measure with a syringe rather than a cap, and if you have TRITON stock bought before the change, check the label before you carry an old dose across.

You need an ICP-OES analysis before you dose this. TRITON publish no general dosing schedule for single elements — the dose comes from the DOSE tab of your own ICP analysis, and targeted single-element correction is the entire method the range is built around. Dosing a macro element blind is how a reef tank acquires an imbalance harder to fix than the one it started with.
