Cleansol Alkalinity Up – Alkalinity Increaser & pH Stabiliser for Swimming Pool
About this item
Cleansol Alkalinity Up is a pool alkalinity increaser and pH stabiliser that raises total alkalinity to the ideal 80–120 ppm. When alkalinity is low, pH jumps up and down every day – you keep adding pH chemicals, the water stays unstable, chlorine works poorly and metal parts corrode. Alkalinity Up fixes the root cause so pH stays where you set it. Pool grade powder with no fumes, supplied with a 10 g scoop. Packs: 1 kg balti, 5 kg bucket and 25 kg bag.
Raises alkalinity · stops pH bounce · 2 scoops (20 g) per 1,000 L ≈ +10 ppm · 24-month shelf life
Test → dissolve in a bucket → pour near the return jets → pump 6–8 hours → retest next day
Which one do I need?
| Alkalinity below 80 ppm | Cleansol Alkalinity Up (this product) – fix this first |
| pH below 7.2, alkalinity OK | Cleansol pH Up |
| pH above 7.6 | Cleansol pH Down |

Why alkalinity matters
Think of alkalinity as the shock absorber for pH. Between 80 and 120 ppm it soaks up the acids from rain, swimmers and chlorine, so pH stays steady. Below 80 ppm, pH swings every day – you fix it on Monday and it has drifted again by Tuesday. Unstable pH weakens chlorine, stings eyes and slowly corrodes ladders, pumps and grout. Rain, fresh water top-ups, acid dosing and TCCA chlorine all pull alkalinity down, so test it weekly.
Dose chart – how much do you need to raise?
| Pool | Water | +10 ppm | +20 ppm | +30 ppm (max at once) |
| Plunge pool | 10,000 L | 200 g | 400 g | 600 g |
| Small home pool | 25,000 L | 500 g | 1 kg | 1.5 kg |
| Villa pool | 50,000 L | 1 kg | 2 kg | 3 kg |
| Society pool | 1,00,000 L | 2 kg | 4 kg | 6 kg |
| Hotel pool | 2,00,000 L | 4 kg | 8 kg | 12 kg |
1 scoop = 10 g. Pool volume (L) = length × width × average depth (m) × 1,000. Need more than +30 ppm? Add the rest the next day, then retest.
How to use
- Test total alkalinity (and pH). Use Alkalinity Up when alkalinity is below 80 ppm.
- Measure – 2 scoops (20 g) per 1,000 L for every +10 ppm.
- Dissolve in a plastic bucket of pool water.
- Pour slowly in front of the return jets with the pump running.
- Circulate 6–8 hours. Swimming is fine after about 1 hour of mixing.
- Retest next day, then fine-tune pH with pH Up or pH Down if needed.
Balance in the right order
| Step 1 | Alkalinity Up – bring alkalinity to 80–120 ppm, retest next day |
| Step 2 | Set pH to 7.2–7.6 with Cleansol pH Up or Cleansol pH Down – it will now stay there |

Pool green, cloudy or smelly?
Unbalanced water is one of the top reasons. Follow the step-by-step rescue guide.
Safety & storage
- Dust may irritate eyes. Wear gloves and safety glasses; in eyes, rinse with clean water for 15 minutes.
- Do not mix with other pool chemicals in the bucket – add each one separately.
- Keep the lid tightly closed and dry, in a cool place, out of reach of children.
Frequently asked questions
What is total alkalinity and why does it matter?
Total alkalinity is the water's buffer – a "shock absorber" for pH. Between 80 and 120 ppm it holds pH steady. Below 80 ppm, pH swings up and down every day and your pH chemicals get wasted.
How much Alkalinity Up do I add?
2 scoops (20 g) per 1,000 litres raises alkalinity by about 10 ppm. A 50,000 L pool going from 60 to 80 ppm needs about 2 kg. Add at most 6 scoops per 1,000 L (about +30 ppm) at one time.
Should I fix alkalinity or pH first?
Alkalinity first. Bring it to 80–120 ppm, retest the next day, then set pH to 7.2–7.6 with pH Up or pH Down.
Alkalinity Up or pH Up – which do I need?
Test both. Alkalinity below 80 → Alkalinity Up first. pH below 7.2 with alkalinity OK → pH Up. pH above 7.6 → pH Down.
Will Alkalinity Up change my pH?
Only slightly – it nudges pH up a little. That is why it is the safe first step before using pH Up.
Why does alkalinity drop?
Rain, topping up with fresh water, acid dosing and TCCA chlorine all lower it slowly. Test weekly, more often in the monsoon.
Can I swim after adding it?
Yes, after about 1 hour of pump mixing, once it has fully dissolved.
How long does it last in storage?
24 months from manufacture, kept dry and tightly closed.

Safety & first aid
Keep out of reach of children and pets. Do not mix with other cleaners, especially bleach and acid-based products. Avoid contact with eyes; if it happens, rinse with plenty of clean water.
Test on a small hidden area first. Close the cap after use and store in a cool, dry place away from direct sunlight.
