Sea Lab Trace Element Blox

TRACE ELEMENT BLOX takes the hassle out of ensuring your aquarium has adequate trace elements. Your fish and invertebrates requires these elements for survival.

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, it allows you to start enjoying your fish and aquarium rather than be a slave to it.

Ensures ample Calcium, Magnesium, and Iron for stable alkalinity.

Ensures correct trace elements for fish and invertebrates for excellent health and growth.

Very easy to use.

Very hard to overdose.

Recommended for Freshwater African Cichlids.

Trace elements are necessary to maintain a healthy environment for your fish and invertebrates. When using Tri-Base Pelletized Carbon for your bio media and filtration system, it will absorb trace elements that are in your aquarium water. By using the Sea Lab Trace Element Blox, the needed trace elements are added to the tank automatically. NO measuring, and NO worry that your marine animals and fish are not getting the sufficient trace elements they require. Sea Lab Trace Element Blox are compatible with all types of marine mix and natural seawater. They are compatible with all conventional filtering materials such as sand, gravel, activated carbon, bio media, TBPC, polyester fiber materials, and urethane foams.

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.
