What are the Shelf Life of Different Pool Chemicals?

LIQUID CHLORINE

Sodium Hypochlorite‍ or chlorine bleach, is an unstable form of chlorine, in that it can lose up to 50% potency within the first 6 months, and 90% within one year. If subjected to hot or cold temperatures or direct sunlight, degradation occurs more quickly. You'd better choose our more stablized Chlorine tablets (Trichlor or Dichlor) or granular (Trichor, Dichlor, Calcium Hypochlorite) if you want to keep your chlorine longer time for use.

TRICHLOR TABLETS

Trichlor tablets have the longest chlorine shelf life. We have lab tested our individually wrapped tablets for potency over time. At 36 months, AQUACLEAR Chlorine tablets still have 98% of their original available chlorine, when stored in constant 50-70° F temps with a tightly closed bucket lid. In the right conditions, trichlor tablets can remain viable for more than 5 years. AQUACLEAR TRICHLOR products have Trichlor Powder, Trichlor Granular, Trichlor Tablets, Trichlor Multi-Function tablets for your choices. Actually Trichlor are our most stable and economical pool chlorine products. AQUACLEAR is a major Trichloroisocyanuric Acid‍ (Trichlor, Trichloro) manufacturer, factory in China. Our trichlor products are of high chlorine ( up to 92% sometimes), low residue which will always keep your pool water Clean and Clear. You may write us mail or call us directly for any new purchase.

CALCIUM HYPOCHLORITE POOL SHOCK

Calcium Hypochlorite, AQUACLEAR pool shock or granular chlorine (sinopec super-chlor Calcium Hypochlorite or other commercial names), also has a long shelf life, if kept in an air tight container, in a cool and dry (indoor) location. AQUACLEAR Calcium Hypochlorite normally packed in 1kg to 50kg plastic jars or drums, it absorb moisture from humid air, the drum packed AQUACLEAR Calcium Hypochlorite can be stored for at least 24 months from production date. For longer term storage, re-pack into freezer bags or buy chlorine granules, sold in buckets and plastic drums. Properly stored, AQUACLEAR Calcium Hypochlorite has a shelf life of more than 5 years. AQUACLEAR Calcium Hypochlorite is made of advanced Sodium Process technology, it is of very high chlorine (up to 72% sometimes), it is a fast dissolving and repid into function chlorine products, we have AQUACLEAR Calcium Hypochlorite (Sodium Process) 65%, 70% Granular, tablet for your choices.

CHLORINE STABILIZER

Cyanuric acid, or chlorine stabilizer, will maintain potency indefinitely, even if it absorbs moisture, as long as it is stored in a tightly closed container. Be sure to label cyanuric acid as Conditioner or Stabilizer, so the white powder won't be confused with another chemical should the container label fade or become unreadable.

ALGAECIDES

When properly stored (cool and dry indoor location), pool algaecides are quite stable and most will maintain potency for up to 5 years. Temperatures over 75° F and direct sunlight will reduce algaecide shelf life, especially lower concentration algaecides (10% and 30% formulations). However, freezing temperatures can ruin pool algaecide.

CLARIFIERS

Similar to algaecides, pool clarifiers have a shelf life of up to 5 years, stored tightly closed in consistently cool temperatures, in a dark cabinet or container. Outdoor storage in a garage or shed with high temperatures can reduce effectiveness, and freezing can damage the polyamide structure, rendering clarifiers useless.

ALKALINITY & CALCIUM ENHANCER

Sodium bicarbonate and calcium carbonate are both dry white powder or flake chemicals, and both can remain viable and potent for more than 5 years. As with other dry pool chemicals, shelf life can be extended with tightly closed lids to keep out moisture, which can cause clumping and hardening of your water balance chemicals.

PH INCREASER

Sodium carbonate or soda ash (pH Increaser) can remain viable for more than 5 years, when stored in an air-tight container, to lock out moisture. If stored outdoors, humid conditions can pull moisture into the bucket, clumping and hardening, but also converting sodium carbonate to sodium bicarbonate over time, slightly reducing the effect on pH.

PH REDUCER

Sodium Bisulfate and muriatic acid could have a 5 year shelf life; however pH decreasers are acids, and a larger shelf life concern about pH decreasers is the strength of the container. Over time, thin plastic bottles or packaging can break down from contact with acids. So, although pH-Down chemicals last for years, you should probably use them up.
