ATI Fluorine Supplement 1000ml
Fluorine is used for targeted supplementation in reef aquariums where natural seawater levels have been found below optimal levels through ATI ICP testing.
Adding 5ml of fluorine to 100 litres of aquarium water will increase the fluorine concentration by 1 ug/l.
Fluorine supports the coral calcification process. However, care should be taken when adjusting fluorine levels. We recommend starting with 1ml per 100 litres of aquarium water and monitoring results through the next ICP test before gradually increasing the dosage.

FAQ
What is the recommended starting dose of fluorine for a reef aquarium?
We recommend starting with 1ml of fluorine per 100 litres of aquarium water to monitor the effect and ensure safe levels before adjusting.
How does fluorine benefit coral health?
Fluorine supports the calcification process in corals, which is essential for their growth and structural development in reef aquariums.
Can I increase the fluorine level beyond the initial dose?
Yes, but only after monitoring the current fluorine levels via an ATI ICP test and observing the coral response. Gradual increases are advised.

Stephanie Robertson –
I used this supplement after my ICP test showed low fluorine levels. Started with 1ml per 100 litres and monitored over two weeks. My corals showed improved growth and coloration. The product is easy to use and matches the recommended dosage.
William Miller –
The fluorine supplement helped stabilize my reef tank’s chemistry. I followed the recommended starting dose and waited for the next ICP test before increasing. My polyps are more active now.
Sally Walker –
After using this product for a month, I noticed better skeletal development in my branching corals. I’m confident in the product’s effectiveness when used as directed.
