Red Sea Reef Care Kh/alkalinity Foundation B 1ltr

Description

Red Sea Reef Care KH/Alkalinity Foundation B 1ltr — Litre bottle of liquid buffer for daily reef dosing

Because alkalinity is consumed faster than calcium or magnesium, the buffer is the bottle that runs out first, which is why the litre earns its place. Red Sea Reef Care Kh/alkalinity Foundation B 1ltr (SKU: RED281b) is the 1 L size of Red Sea’s KH/Alkalinity Foundation B, a complex blend of carbonate and the natural buffers found in seawater, made to hold alkalinity and pH steady as corals build skeleton. It is the B part of the Foundation A, B and C system in the Reef Care Program, with 1 mL raising the alkalinity of 100 L by 0.1 dKH, equal to 0.036 meq/L.

Red Sea’s recipes give each aquarium type its own alkalinity, from 7.0 dKH in an ultra-low-nutrient system through 8.0 for SPS-dominant tanks and 11.5 for a mixed reef up to 12.6 dKH for a frag tank, and the right dose is whatever a four-day uptake test shows the tank consuming, checked weekly. Red Sea’s limit is 1.4 dKH of change per day, dosed into the sump after magnesium and before calcium. A litre raises 200 L by 50 dKH in total, so a tank that size losing 0.5 dKH a day empties it in about 100 days. Matched litre bottles of Foundation A (RED280b) and C (RED282b) complete the set.

Usage & Application

When to Use

• Reefs of 150 to 400 litres: A litre of buffer for a home display with a steady alkalinity draw.
• Dosing-pump reservoirs: The alkalinity channel filled from one bottle.
• Mixed and SPS reefs: Daily dosing to the 8.0 to 11.5 dKH recipes.
• Program users: The B line matched with A and C in the same size.

Dosing & Administration Guide

• Four-day test: Hold alkalinity at target, dose nothing for four days, divide the drop by four.
• Dose rate: 1 mL per 100 L per 0.1 dKH, within a 1.4 dKH daily limit.
• Order and place: Magnesium, then this buffer, then calcium, ten minutes apart, in the sump.
• Weekly check: Total-alkalinity test kit, log the reading, adjust the daily dose.
