Applying Chemicals

  • Chlorine (Tri-Chlor/Cal-Hypo) CL (3 – 5ppm)
    • Info
      • Trichlor- CYA based, if used in excess can raise stabilizer levels to high resulting in a drain.
      • CalHypo- Calcium based, if used in excess can raise calcium levels to high resulting in a drain.
        • When using calhypo, keep separate from CYA, water, and a closed lid. This can result in fire or explosion, the byproduct being mustard gas.
    • Metric
      • 1lb per 10,000 gallons raises level 10ppm
    • Example
      • 20,000 gal pool uses 2lbs chlorine to raise 10ppm
    • IMPORTANT: During the summer months add chlorine every week. Don’t forget the tabs, without them the chlorine will not last 7 days.

 

  • PH (Muriatic Acid) 7.2 – 7.6
    • Info
      • Low PH= Acidic water causing your Chlorine to burn off quickly
      • High PH= Corrosive water causing scale/calcium build up and Chlorine lock.
    • Movement
      • To lower PH add Muriatic Acid to water in a bucket at a 50/50% ratio.
        • Rule of thumb, to lower Ph use a quarter gallon acid or 32oz every 1 – 2 weeks, if your Alk is in line you should rarely be using acid.
        • In a salt pool add 32oz every week to prevent calcium build up.
      • To raise PH; in the event your ALK is between 80 and 120 and your Ph is low, use Soda Ash.
        • PH (Soda Ash) – 4 ounces per 5,000 gallons to raise PH
        • Ex: 20,000 gallon pool needs 16 ounces, check back next week.

 

  • Alkalinity (Sodium Bicarb) ALK (80 – 120ppm)
    • Info
      • Always fix 1st, if your ALK is offset the rest of your chems will remain unbalanced.
      • This is imperitive to remember, a perfect alkalinity will always pull your PH back to normal.
      • The ideal Alkalinity is 90 to 100ppm.
      • If it lowers to around 60 your PH will become chaotic never remaining in place, causing your CL to either lock up or burn off. If it is above 120, which in my opinion is too high the PH will remain high causing your CL to lock up and potentially begin calcifying the walls.
    • Movement
      • To raise ALK add Alkalinity (Sodium Bicarb) ALK – Continued
        • Reference weight by volume chart.
      • To lower ALK pour acid directly in to water in one spot in the deep end.
        • 1 gallon of acid lowers on avg. 50ppm

 

  • Cyanuric Acid (Stabilizer) CYA (30ppm – 120ppm)
    • Info
      • Stabilizer is what stops UV rays from sucking the Cl out of your pool. When CYA levels get to low, Cl begins to burn off to fast. When CYA levels get to high, Cl begins to lock up, if this happens the pool needs to be drained asap. You will begin to see algae on the wall that is next to impossible to brush off.
    • Movement
      • 3 lbs per 4,000 gallons will raise CYA 40ppm
      • Ex: 20,000 gal pool uses 15lbs to raise 40ppm
      • Play it safe and don’t over stabilize your pools. Check every week until you get desired outcome.

 

  • Salt
    • Info
      • 1 Bag of salt will raise levels avg. 250 to 400ppm depending on pool size.
      • Keep salt levels between 3000 – 3400ppm
      • 3400ppm is optimum level.
      • In the event your salt levels drop below 2600ppm the cell will shut off, if this happens the pool can turn green in a day or two.

 

  • Calcium (Scale) C (200ppm – 400ppm)
    • Info
      • The level of Calcium in your water directly relates the level of calcium in your walls. You desire to have equilibrium to these levels. The preferred levels are between 200 and 400ppm due to most plaster being balanced around 250ppm. When your Calcium drops below 200ppm the water will try to pull the Calcium out of the walls leaving pitting and weak plaster. When your Calcium raises above 400ppm the Calcium in the water will try to push itself into the plaster causing staining.
      • In the event that it gets up to 600ppm recommend drain, if really low you will need to add calcium but if it’s around 170 it will raise on its own.

 

  • TDS (Total Dissolved Solids) 0 – 1200ppm
    • Info
      • Your TDS is exactly how it sounds; the combined amount of material molecules in the water, when these levels become too high your chlorine begins to combine with the excess molecules at a rapid pace causing your chlorine to become less effective.
      • NOTE: When using metal based algaecides such as copper or silver algaecides you must pay attention to the TDS levels in the water, if they are too high when applying these products it will cause severe staining of the plaster. Hence the reason we don’t use them.
      • 1200ppm is the preferred max but they can raise all the way up to 2000ppm before a drain is absolutely needed.

  • Alkalinity Example Chemical Reading
    • 25,000 Gallon pool has 60ppm alkalinity reading. You need to raise it back to 100ppm which is a 40ppm difference.
      • 26.25oz will raise 10ppm
      • 26.25oz x 4 = 105oz
      • 105oz divided by 24oz = 4.5 scoops
      • 4.5 scoops equal 15lbs

Yellow Algae Treatment

 

  • Steps
    1. Backwash the filter or schedule filter clean if needed.
    2. Brush algae with stainless steel brush
    3. Balance chemicals to normal levels
    4. Treat with corresponding treatment exactly as labeled.

 

  • Other info
    • Note: addition of granular 90 will not raise chlorine levels but act as a buffer against the yellow trine. Always balance your chemicals and chlorine levels to normal range and then perform treatment on top of adjustments.
    • Yellow trine is to be broadcasted throughout the water
    • Granular 90 is to be added through the skimmer. Ensure it isn’t a skimmer attached to the in floor system but to the main pump.
    • Do not use Cal-hypo as substitute for Granular 90

 

  • Severe Algae
    • 15k Gallons:
      • 12oz Yellow trine/20oz Granular 90
    • 25k Gallons:
      • 20oz Yellow trine/68oz Granular 90
    • 35K Gallons:
      • 28oz Yellow trine/96oz Granular 90
  • Minor Algae
    • 15k Gallons:
      • 6oz Yellow trine/20 oz Granular 90
    • 25k Gallons:
      • 10oz Yellow trine/34oz Granular 90
    • 35k Gallons:
      • 14oz Yellow trine/48oz Granular 90

 

  • Note: pool must run for 24 hours after the treatment is performed. Inform customer of these conditions.

 

  • Preventative Algae treatment: using Yellow trine, add the following every week to every other week:
    • 1oz per 10k Gallons – will prevent algae from growing in the first place.
