Seachem Reef Advantage Strontium 4 kg (8.8 lbs)
Reef Advantage Strontium restores and maintains strontium to levels found in natural sea water. Strontium is utilized by corals in the same manner as calcium and holds a similar importance in maintaining a vigorous level of growth. It is most useful in densely populated aquariums requiring a continuous supply of strontium. Reef Advantage Strontium is a highly concentrated (30,000 ppm), ionically balanced strontium supplement that can be added directly to the tank (no predissolving required). 600 g treats 20,000 L (5,000 gallons).
BEGINNER: Use a level teaspoon per 150 L (40 gallons) twice a week. May be added directly to tank.
ADVANCED: Check strontium level, then follow dosing regimen above until strontium is adjusted to 8 to 12 mg/L. Each dose will raise strontium by about 2 mg/L. Size or frequency of dose can be adjusted. Thereafter, use as required to maintain strontium.
EXPERT: After determining the strontium depletion rate, set up a continuous drip system. Use the following formula to determine how much to add to your top-off water: t=0.02vs (t=teaspoons to add to top off water, v=volume of tank in gallons, s=amount to raise strontium in mg/L). For example, if you want to raise strontium by 8 mg/L in a 50 gallon tank, then you would add 0.02x50x8=8 teaspoons into the top-off water.
HINTS: Use the Reef Status: Strontium to check strontium levels.
DO NOT OVERDOSE: Excess strontium may enhance the loss of carbonate alkalinity. Do not directly mix with any carbonate supplement. Best if strontium and carbonate additives are added on alternate days or at least 30 minutes apart.
