Kent Marine Turbo Calcium 800 g (1 Qt) Information

Product Manuals & Documentation

Do you need calcium supplements for your corals and other hard-shelled marine pets? If you want a dry calcium source that will immediately raise the calcium levels for your aquatic creatures to dig in, you must have Kent Marine Turbo Calcium Pet Store. This product is an excellent source of biological calcium for optimum growth of creatures such as snails, hard tube worms and clams and other shellfish you have been growing in your tank.

Calcareous algae grow extravagantly colorful when you supply your tank with this calcium feed. Your corals can have a sturdier skeleton because of the ample amount of calcium available for them. Your corals will open more, too! This supplement does not contain phosphates and nitrates, which may lead to an unwanted algal bloom, ammonia buildup and pH alteration. It does not have gluconates, EDTA and other organic compounds that can raise the levels of dissolved organic carbon. This product is very easy to use, however, as in all supplements, you should use it in moderation and follow the instructions for proper usage, unless you want to keep your tank more disturbed.

Kent Marine Turbo Calcium, available in 800 grams, is an excellent calcium supplement. Because it does not contain other chemical preservatives, it will not harm your fishes and other organisms. It is an easy-to-use and effective merchandise.

TURBO CALCIUM provides bio-available calcium for lush growth of purple, pink and green calcareous algaes, snails, hard tube worms and clams. Corals will open more and stay attached to their skeletons better, with regular use. Phosphate & nitrate free! Contains no gluconates, EDTA, or other organics to raise DOC levels, as many competing products do. This product is the main ingredient in other calcium supplements in economical dry form! TURBO CALCIUM alone can provide all the calcium your reef will need, but for maximum results, use Kent Kalkwasser Mix first, then raise calcium level with this product. Strontium addition via use of Kent Marine Strontium & Molybdenum Supplement or TURBO STRONTIUM is absolutely necessary. Use of Coral Vite, and Essential Elements are beneficial, as well.


Start off using 1/8 teaspoon of granules per day on a 50 gallon, lightly loaded reef tank or 1/4 teaspoon of granules on a heavily loaded one. Since animals use calcium, and gallons do not, regular testing of calcium level by a good calcium test kit (HachTM is recommended) is absolutely necessary with use of TURBO CALCIUM. Adjust amount of addition of the product to achieve a calcium level of about 400 mg/l. A higher level may result in rapid calcium compound precipitation and deposits which can possibly be destructive to pumps and other sensitive system equipment. It is recommended that you regularly check impellers and other delicate equipment for calcium deposits if you run higher (above 400 mg/l) system calcium levels! For best results adjust system KH to 8 to 10 dKH with Superbuffer-dKH or Marine Aquarium pH Buffer.

Considerations for use:
This product contains anhydrous calcium chloride in dry form. It should be used by experienced reef keepers who desire to rapidly raise the calcium level in their tanks. Novices or casual users should use Kent Marine Concentrated Liquid Calcium or Kalkwasser Mix instead of this product. PRODUCT GETS VERY HOT WHEN MIXED WITH WATER, USE RUBBER GLOVES, AND ALWAYS MIX OUTSIDE THE TANK OR ADD GRANULES TO SUMP OF WET-DRY FILTER SO THEY DON`T LAND ON ANY ANIMALS! ABSORBS MOISTURE, KEEP TIGHTLY CLOSED!

Anhydrous calcium chloride.

Comments: Excellent product. I use it in between kalk drips and it is quick and easy. It quickly dissolves in a small amount of water, then can go directly in the sump or tank.

Comments: This is a highly concentrated dry calcium additive that I've found to be one of the easiest to use. I use it in conjunction with the same manufacturer's "Coral Builder" and "Superbuffer" products. Overall, a solid product.

Comments: Got calcium up >420mg/L in 1 week, best results when I added to monthly 20%water change @500mg/L; by next AM corraline grew on front glass. Soo much growth, I think corraline has become self-aware...

Comments: I have found that the turbo calcium is a great way to add calcium without making changes to Alkalinity. My calcium reactor has been shut down for six months now and I use the Turbo Calcium to handle all my demand.
