Pool Chlorine

Trichlor – Slow and Steady

Trichlor is generally more concentrate than other forms of chlorine and dissolves slowly. It comes in powder and tablets and is designed to be added through your skimmer box. It’s gradual release helps maintain chlorine levels, reducing but not eliminating the need for constant monitoring. Trichlor is highly reliable, but because it releases chlorine slowly, it’s important to check your chlorine levels regularly to make sure everything stays balanced. Many pool owners choose Trichlor tablets for periods when they might be away for a few days, as it continues to sanitise the water without intervention.

Dichlor – Fast and Flexible

Dichlor is a good middle-ground option. It needs to be pre-mixed into a bucket of water. It dissolves quickly and sanitises your pool efficiently, making it easy to use for routine dosing or when you need to give your water a quick boost. Because it dissolves rapidly, Dichlor works well for both weekly maintenance and emergency situations, such as cloudy water or a sudden algae outbreak. It’s important to check your chlorine levels regularly. It’s a convenient choice for pool owners who want reliable chlorine without worrying about slower dissolving or heavier maintenance.

Cal-Hypo – Strong and Reliable

Calcium Hypochlorite, or Cal-Hypo, is another popular choice. It’s perfect for weekly maintenance or giving your pool a shock treatment to clear cloudy water or tackle algae. Cal-Hypo also needs to be pre-mixed into a bucket of water, is fast-dissolving, which makes it ideal when you need immediate results. Many pool owners rely on it for quick fixes or to get ahead of potential water issues before they become bigger problems. Regular testing is important, but many pool owners rely on Cal-Hypo because it’s cheaper, dependable and easy to use. Its strength makes it especially useful for larger pools or during peak swimming season when pools are used more frequently.

Liquid Chlorine – Simple and Cost-Effective

Liquid chlorine is the everyday, no-fuss option. You simply pour it in front of the pool jets, and the circulation does the rest. Because it isn’t bound to stabilisers or other additives, liquid chlorine is a go-to choice for pools with high stabiliser or calcium levels, or where quick action is needed especially for green pool cleanup’s. It’s also very straightforward for pool owners who want a low-maintenance solution. While cheap it has some down sides. The 15L containers are bulky to carry and there is the risk of leaks from the vented cap, it can be hard to pour it out without a tap and suitable placement off the ground. For ongoing use we recommend it be placed high enough to allow use of a jug to measure and pour into the pool to assist minimising spillages[IT1] .
