Seachem Reef Builder

Seachem Reef Builder is used to raise carbonate alkalinity (KH) in marine aquariums without impacting pH and without depleting calcium, magnesium, or strontium.

  • Raises carbonate alkalinity (KH) with minimal impact on pH
  • A blend of carbonate sources that will not lower pH as competing bicarbonate-only products can
  • Will not deplete calcium, magnesium, or strontium

Seachem Reef Builder raises carbonate alkalinity without immediately impacting pH. With long-term use, there will be a tendency to stabilize at pH 8.3. Carbonates and calcium are essential to all coral growth. If either becomes deficient, coral growth will cease, followed by a rapid decline in coral health. Used as directed, Reef Builder™ will not deplete calcium, magnesium, or strontium which usually tend to precipitate with increasing alkalinity. Reef Builder™ and Reef Buffer™ may be used together. Use Reef Builder™ to raise carbonate alkalinity without affecting pH. Use Reef Buffer™ to raise carbonate alkalinity and pH.
Why It's Different

Unlike the competition, Reef Builder™ contains calcium, magnesium, and strontium to compensate for the inevitable loss which occurs when raising alkalinity. It also contains sufficient magnesium to restore magnesium routinely depleted.

Directions

BEGINNER: Use 3 g (half a level teaspoon*) per 150 L (40 gallons) twice a week. Dissolve in at least 250 mL (1 cup) of freshwater. Check alkalinity every 2 weeks and adjust amount or frequency accordingly.

ADVANCED: Check alkalinity, then follow addition regimen above until alkalinity is adjusted to 4–5 meq/L. Each 3 g/150 L will raise alkalinity by about 0.25 meq/L. Quantity or frequency can be adjusted, but do not exceed 12 g/150 L per day. Thereafter, use as required to maintain alkalinity.

EXPERT: After determining the alkalinity consumption rate, set up a continuous drip system. Use the following formula to determine how much to add to your top-off water: m=0.08va (m=grams to add to top off water, v=volume of tank in liters, a=amount to raise alkalinity in meq/L). For example, if you want to raise your alkalinity by 1 meq/L in a 200 liter tank, then you would add 0.08x200x1=16 g into the top-off water. [For reference: 1 gallon*=3.8 liters, 6 g=1 teaspoon*]. Notes: Use MultiTest:™ Marine pH & Alkalinity to measure total alkalinity.HINTS: Use MultiTest:™ Marine pH & Alkalinity to measure total alkalinity.

Good Sized Treat for a 35 llbs dog, smaller it will interfere with daily meals.
Flavor Name: Chicken Chips, Size: 1 Pound (Pack of 1)
The texture is hard as a chew treat, my two small dogs can smell the container being opened and tapping my leg to give it all to only one. Size is one chicken piece rolled tightly, so i have to cut it up completely and share it between my 15 yr old MinPin and my 2 yr old miniature shepherd mix. This will be used only every other day so it will take about a month or more to us first of two bags. The cost also drew my eye and the fact that just two ingredients which should not affect the health of my MinPin.
