Sea Lab Trace Element Blox

Trace elements are important for maintaining a healthy environment for your fish and invertebrates. By using the Sea Lab Trace Element Blox the needed trace elements are added to the tank automatically. Absolutely no measuring or worries that your aquatic creatures are not getting the proper amount of trace elements they need. Sea Lab Trace Element Blox are compatible with all types of marine mix and natural seawater. Simply put one blox under the sand next to the aquarium glass. It dissolves slowly as your trace elements are dispersed. Combined with Hiatt's pH Adjustment Rock, you can enjoy your fish tank rather than being a slave to it. They are suitable with all approved filtering materials such as sand, gravel, activated carbon, bio media, (TBPC), polyester fiber materials, and urethane foams. Each individual bloc treats 20 gallons.

CAUTION: Some synthetic resin filtering materials may release ammonia back into the system when water chemistry is normalized by water change. If you are using such materials, remove the recharge, or replace them before adding the Trace Element Blox.

Recommended Dosages: Dosage is not critical and the Blox cannot be overdosed. Use 1 nugget for 10 gallons, and 1 blox for 50 gallons until it is dissolved. (If you overdose, the Phosphate is elevated and the algae love it.) The blox should be placed under the sand next to the glass. When they are dissolved, then another one is added. This way, the blox will not be worn down by water abrasion.
