Balanced Supplements as a Method
of Calcium & Alkalinity Supplementation

These compounds, available in dry or two-part liquid formulations, are capable of maintaining both high calcium levels and alkalinity without causing a build-up of unwanted compounds. This method of maintaining calcium and alkalinity in reef aquariums has become very popular due to their ease of use.

Advantages

• Readily available.
• Easy to use - Once the desired levels of calcium and alkalinity are achieved, all that is necessary is to add equal amounts of the two-part formulation according to manufacturer directions.
• Safe - If used per directions, there is little chance of overdosing or shocking the aquarium inhabitants.
• Supplementation can be easily tailored - Simply increase the daily amount when the aquarium inhabitants grow or when more animals are added.

Caveat - Though reliable and easy to use, there are a few shortcomings to the use of balanced calcium supplements.

• Can be expensive for large aquariums - relative to other methods, it is the most expensive method for maintaining calcium over the long term.
• Somewhat tedious - Each of the two-part balanced liquid supplements must be carefully measured out in equal amounts and added daily.
• Problematic to correct - In the event where the alkalinity/calcium balance is distorted, it will be necessary to get things in balance through some other means which could exacerbate the situation.
• Salinity may increase over time with regular use.
