Description

Reef Builder 300gReef Builder effectively increases carbonate alkalinity (KH) without causing an immediate change in pH levels. With consistent use over time, it tends to stabilize around pH 8. 3. When used according to the guidelines, Reef Builder will not reduce levels of calcium, magnesium, or strontium, which typically precipitate as alkalinity rises.

Reef Builder effectively increases carbonate alkalinity (KH) without causing an immediate change in pH levels. With consistent use over time, it tends to stabilize around pH 8.3. When used according to the guidelines, Reef Builder will not reduce levels of calcium, magnesium, or strontium, which typically precipitate as alkalinity rises.


KEY FEATURES:

  • Enhances carbonate alkalinity (KH) with little effect on pH
  • A unique combination of carbonate sources that won't lower pH, unlike other bicarbonate alternatives
  • Will not diminish calcium, magnesium, or strontium levels

DIRECTIONS:
Beginner
Administer 3g (1/2 level teaspoon) for every 150L (40 US gallons) two times a week. Mix in at least 250mL (1 cup) of freshwater. Monitor alkalinity every two weeks and modify the dosage or frequency as needed. For accurate measurements, utilize the Seachem Digital Spoon Scale.

Advanced
Measure alkalinity, then adhere to the dosage regimen outlined above until alkalinity reaches 3-6 meq/L (8-17 dKH). Each 3 g/150 L will increase alkalinity by approximately 0.25 meq/L. You can adjust the quantity or frequency, but do not exceed 12 g/150 L per day. After that, use as necessary to sustain alkalinity.

Should have got this ages ago!
Color: Gold, Material Type: Stainless Steel
Heavy enough to stay in place, but light enough to pick up and carry to the cleanup site. Very simple, but elegantly fashioned.

Heavy Duty Paper Towel Holder
Color: Brushed Nickel, Material Type: Stainless Steel, Color: Brushed Nickel, Material Type: Stainless Steel
Nice looking, heavy duty paper towel holder. Looks like it'll be durable. The top did have a couple of dark, tarnished looking spots but it's not too noticeable.
