ReviewsCalcium Polarizer

Zoo Med (3 Pack) Laboratories Nano Banquet Block Mini, 0.3 oz Each

CONCENTRATED BLEND: Reef Calcium is a concentrated bioavailable polygluconate complexed calcium intended to maintain calcium in the reef aquarium without altering pH..
POLYGLUCONATE COMPLEXACTION: Increases the bioavailability of the calcium, provides a rich source of metabolic energy to help maintain peak coral growth, and it prevents calcium precipitation/alkalinity depletion..
ORGANIC CALCIUM: Reef Calcium Reef Calcium utilizes a chained organic calcium rather than an ionic calcium..
USE: Reef Calcium may be used alone to maintain calcium but will provide enhanced levels of coral growth when used in conjunction with an ionic calcium supplement such as Seachem’s Reef Complete or Reef Advantage Calcium..
DIRECTIONS: Add 1 capful (5 mL) per 80 L (20 US gallons) twice a week. You can increase the amount or frequency based on growth response but do not exceed 3 capfuls per 80 L (20 gallons) per day. Each capful will raise calcium by about 3 mg/L..

58mm 3 Piece Filter Kit (UV-CPL-FLD): UV filters reduce haze and improve contrast by minimizing the amount of ultraviolet light.
CPL filters (Circular Polarizer) are great for removing unwanted reflections from non-metallic surfaces such as glass or water.
FLD filters allow for shooting under fluorescent lighting.
This kit is compatible with all 58mm lenses. Please verify your camera’s lens thread size before ordering. Your camera’s lens thread size will be marked somewhere on the lens barrel or printed underneath your lens cap. This number is always preceded by a “Ø” (diameter) symbol. For example: Ø58 = 58mm lens thread size.
