ProdiBio Stronti 6 Vials

ProdiBio Stronti supplies the strontium vital for hard coral development and coralline algae growth in closed reef systems.

• Strontium is vital for coral development in closed marine water reef tank environments
• Stimulates the growth of hard corals
• Assists in the development of the red and coralline algae that produce the live rock decor
• Stronti provides all the strontium needed for optimum and healthy coral,
  clam and coralline algae growth.

When should Stronti be used ?

• In your marine water tank for the development and growth of your corals
• The strontium diminishes proportionally with the calcium in a reef aquarium, so you can gauge the strontium demand by examining the calcium content.

How to use Stronti ?

Part of maintaining stable reef chemistry — see our guide to Calcium & Magnesium for how this product fits into dosing a reef tank.

Compatibility

Stronti+ adds the strontium that hard corals, clams and coralline algae consume continuously. Trace elements are replenished constantly in the ocean; in a closed reef tank the concentration drops quickly and has to be offset.

• Stimulates hard coral growth and supports the red and coralline algae that colour live rock.
• Corals, clams and coralline algae fix strontium into their skeletons alongside calcium, so demand is continuous rather than occasional.
• Prodibio's practical tip: strontium falls in proportion with calcium in a reef aquarium, so you can gauge the strontium demand by watching the calcium.
• Marine reef aquariums. This is a reef supplement and has no use in a freshwater tank.
• Dosed on Prodibio's 15-day cycle: Nano one ampoule per 60 litres, Standard one per 200 litres, Pro one per 2,000 litres.
• Sits alongside the rest of the Prodibio reef range and alongside any other calcium and alkalinity system you already run — it corrects one thing and supplies nothing else.

Prodibio size their ampoules by range rather than by bottle: Nano for aquariums up to 120 litres, Standard for 120 to 1,000 litres, and Pro above that. The ampoule is the same 1 ml either way — what changes is how much water one of them treats.

Pack Size

6 sealed glass ampoules of 1 ml. Prodibio's published rate is one ampoule per 200 litres every 15 days.

• One box is 6 doses. In a 200-litre aquarium that is 6 treatments — roughly 12 weeks of maintenance at Prodibio's schedule.
• Larger tanks use proportionally more ampoules per dose, so the box runs down faster: at 400 litres on the Standard rate you are using two ampoules each time, not one.
• This is the Standard-range pack. Prodibio also make Stronti+ as a Nano blister of 4 (one ampoule per 60 litres) and a Pro box of 10 (one per 2,000 litres).

Prodibio supply this as sealed 1 ml glass ampoules. The glass is the point: it keeps the contents away from oxygen until the moment you use them. Shake the ampoule, put the cap over one tip and press with your thumb to snap it, then turn it open-end down just above the water, snap the other tip and pour.
