Product Information
Product Description
The Large Pool Season Spring Startup Kit is an all-in-one bundle that is recommended for pools up to 30,000 gallons. The kit includes 4 bags of Chlorinating Concentrate, 2 quarts of Stain and Scale Control, 1 quart of Super Water Clarifier, 2 quarts of Algaecide 60, 1 Spring Pill, 1 Blue/White Floating Dispenser, and 1 AquaChek Chlorine 4-Way Test Strips (50 strips). The kit contains everything you need to sanitize, clarify, and protect your pool water. The pre-measured components make pool startup easy, even for first-time pool owners.
Prepare your large pool for the season with this convenient all-in-one kit. It includes essential treatments to ensure you have a crystal-clear, balanced, and algae-free water. It covers all aspects of your pool startup. This makes opening your pool a breeze and stress free! Plus, it is cost effective!
The bag of Chlorinating Concentrate is 99% Sodium dichloro-s-triazinetrione dihydrate. It is stabilized chlorinating concentrate in granular form with 56% available chlorine. It is highly effective for use as a primary sanitizer or shock treatment.
The Stain and Scale Control included in the kit inhibits and prevents scale formation from excessive calcium and staining from iron, copper and manganese. The Super Water Clarifier is a super-concentrated, fast-acting water clarifier. The product clears cloudy water by collecting small particles that are unable to be filtered into larger filterable masses. No dilution is required. And the Algaecide 60 kills and prevents swimming pool algae.
Other products included in this kit are the Aqua Spring Pill, Aqua Chek Chlorine Test Strips, and a dispenser. The Aqua Spring Pill contains a concentrated formula that will reduce scum lines, clarify the water, and improve filter efficiency. The container of Aqua Chek Chlorine Test Strips are chlorine test strips that help to test your pool and spa water. A bonus is the Blue/White Dispenser which slowly and safely releases chemicals like chlorine or bromine tablets into your pool/spa's water.

| High pH | Bring your pH into the desired range of 7.4 - 7.6 ppm. | Maintain a proper pH level by using Haviland pH Reducer. |
| Dirty Filter | Check filtration system. Backwash if necessary. | Use Haviland Liquid Filter Cleaner each spring and fall. |
| Low Free Chlorine Residual | Bring free chlorine into desired range of 1 - 3 ppm. Shock if necessary. | Maintain a proper level using one of the Haviland chlorinating products. |
| High Total Alkalinity | Test total alkalinity and adjust accordingly | Lower total alkalinity to their ideal levels using Haviland pH Reducer. |
Green Water
| Green Water Causes | Solution | Preventive Measures |
| Green Algae (hazy water) | Shock the pool using chlorine based shock at 1 lb. per 10,000 gallons. Let circulate overnight and then adjust free chlorine residual to 1 - 3 ppm. | Add Haviland Algae Kil 50 or Haviland Combat 60 every other week at a rate of 6 oz. per 10,000 gallons |

| Combined Chlorine (chloramine) level too high. The cause is NOT too much chlorine but not enough free available chlorine | Shock the pool using chlorine based shock at 1 lb. per 10,000 gallons. Let circulate overnight and then adjust free chlorine residual to 1 - 3 ppm. | Test pH level daily and maintain pH in 7.4 - 7.6 range. |
Calcium Scale Formation
| Calcium Scale Causes | Solution | Preventive Measures |
| pH too high/Total Alkalinity too high | Add Haviland pH Reducer to bring pH into 7.4 - 7.6 ppm range and to bring total alkalinity down to 100 - 175 ppm. | Maintain pH level in 7.4 - 7.6 range. Maintain total alkalinity level in 100 - 175 ppm |
| Calcium Hardness level too high | If hardness level is too high, some water may have to be drained. Add Haviland Rust-N-Scale per label directions. | Add Haviland Rust-N-Scale every other week at a rate of 6 oz. per 10,000 gallons. |
Corrosion of Metal Parts
| Corrosion Causes | Solution | Preventive Measures |
