What's in the Box
Every winning order ships with one Crystal Cube, wrapped individually and ready to drop straight into your skimmer. Here's what you're working with.
Give your filter a fresh start before you drop the cube in. The Crystal Cube works by clumping microscopic particles together so your filter can trap them. If your filter is already full of debris, it can't do its job properly.
What to do:
- Sand or glass media filter: backwash and rinse thoroughly
- Cartridge filter: remove and hose down the cartridge until clean
- DE filter: backwash and top up with fresh DE powder
- Confirm your pump is running and water is flowing freely
Unwrap the cube and place it directly in your skimmer basket. That's it. No measuring, no pouring, no mess. Just drop it in and let the water flow do the work.
The cube dissolves slowly over the next 48-72 hours, releasing a steady dose of clarifying polymer as water passes through the skimmer.
The cube needs flowing water to work. Run your pump continuously for the first 24 hours to give the polymer time to spread through the pool and start clumping particles.
First 24 hours
Run the pump continuously. You should start seeing a visible difference in clarity within 24 hours.
Days 2-3
The cube fully dissolves. If you used a skimmer sock, the gel residue is contained and easy to remove. Water should be noticeably clearer.
Weeks 1-4
Clarifying polymer keeps working in the water for up to 4 weeks. Maintain normal pump runtime (8+ hours per day) to keep the effect going.
Your cube will run out in 3-4 weeks. Then what?
One cube keeps your pool sparkling for about a month. The 3-Pack gives you 12 weeks of continuous clarity, works out cheaper per cube, and ships free. Set it and forget it for the whole season.

Why It Works
Your filter can't catch microscopic particles like pollen, dead algae, and sunscreen residue. The Crystal Cube releases a clarifying polymer that clumps those particles together into groups your filter can trap, giving you that deep, sparkling "glass" clarity.
The problem is too small to see
Even with perfect chemical levels, your pool can look dull and hazy. The culprit is millions of microscopic particles that pass right through your filtration and hang in the water, creating that frustrating cloudiness that never seems to clear.
More chlorine won't fix it. More backwashing won't fix it. Crystal Cube will.
Slow-release gel technology at work
How the Cube Works
The Crystal Cube slowly dissolves in your skimmer over 3-4 weeks, continuously releasing a clarifying polymer. This polymer acts like a magnet, grabbing microscopic particles and clumping them together into larger groups your filter can easily trap.
Honest Advice from Mr Pool Man
If your pool is constantly cloudy no matter what you do, this usually points to a deeper filtration problem, not just a clarity issue. Crystal Cube is a "finishing touch" designed to polish an already balanced and filtered pool. If you're unsure, contact us with photos and we'll help diagnose it first.

Frequently Asked Questions
Don't worry, this is normal. Sometimes the visible gel cube dissolves within a few days depending on water flow and temperature. The active clarifying ingredients continue working in the water for up to 4 weeks regardless of whether the physical cube is still visible.
Yes. The Crystal Cube is fully compatible with all pool types including Chlorine, Salt Water, Magnesium, and Mineral pools.
Yes, Crystal Cube works well with cartridge filters. Because the cube is so effective at clumping debris, the captured particles can build up on cartridge pleats faster. We strongly recommend using a skimmer sock to contain the cube (available above) and cleaning your cartridge element weekly while in use.
Absolutely. The Crystal Cube is non-toxic and completely safe for swimmers. You can swim immediately after dropping it into the skimmer, no waiting period required.
One cube treats up to 60,000 Litres and typically lasts about 3-4 weeks depending on pump runtime and water flow. The 3-Pack provides up to 12 weeks of continuous clarity.
In high debris environments the gel can get messy. The solution is simple: place the cube inside a skimmer sock or old stocking before dropping it in the basket. This contains the gel while still allowing it to dissolve and work effectively, and cleanup takes seconds.
