Marine Environment Supplements is a proprietary blend of Aqua Craft Products supplements: #6 Bio Elements, #8 Iodide, #9 Strontium + Molybdenum. #10 Sea Trace & #11 Sea Safe.

Quite simply, using Marine Environment Supplements can dramatically improve the working ability of one step salts and reduces the need for purchasing multiple supplements or additives.

The degree of improvement depends on the initial ionic composition and quality (levels, numbers and types of impurities found in various brands) of freshly mixed marine salts.

For the maximum benefit of Marine Environment Supplements or any other Aqua Craft Products supplement or additive, test for calcium, alkalinity, magnesium. Adjust with ACP #1, #2, #3 if necessary.

One cap (6 ml) of Marine Environment Supplements for each new 25 US gallons / 20.8 Imperial gallons / 94.5L of freshly mixed marine salts.

Marine Environment Supplements are also available in 1 gallon size for treating 16,000 US gallons of marine aquarium water.
