Pool Care Guidelines & Cleaning Tips from the Professionals at East Coast Pools, Inc.
WARNING - DO NOT DRAIN YOUR Fibreliner™ POOL
Your Fibreliner™ Fiberglass Pool Liner is specifically engineered to remain structurally sound only when your pool is full of water.
Draining your Fibreliner™ Fiberglass Pool will likely cause catastrophic failure of your Fibreliner™ - VOIDING YOUR WARRANTY!
If, for any reason, you are considering draining your new Fibreliner™ Pool ~ contact the Fibreliner™ Professionals FIRST!
Email East Coast Pools, Inc. or contact the Fibreliner™ Manufacturer Directly.
For best operation, keep the pool water level in the center of the skimmer plate when pool is in use. Low water levels may cause the circulation pump to lose prime resulting in pump damage. High water levels reduce or eliminates the skimmers effectiveness.
The waterline ring (or bathtub ring) that forms around your pool near the waterline is caused by contaminants such as; airborne contaminants (dust, dirt, pollutants) oils, lotions and sunscreens worn by swimmers and even biological organisms that grow near the water surface.
These can usually be easily removed with a solution of warm water and approved swimming pool surface cleaners available at many retailers. Never use abrasive cleaning chemicals or scrubbers like; scrubbing pads, steel wool, metal scrapers or brushes as they may cause permanent damage to the gel coat finish.
Every pool filter is unique and therefore it makes it difficult to tell you what a normal pool filter pressure would be for your specific pool filter. You should consult your pool filter manual to determine the normal pressure range for your specific pool filter.
A general guideline would be to backwash your filter when the pressure gauge climbs 8-10 psi above the normal range and remains there. This will help your filter maintain optimum filtering performance keeping your pool water clean and clear of small particle debris!
(note: ppm = parts per million)
Your Pool Water Chemistry Balance is perhaps the single most important part of your pool maintenance routine. Pool water that is not chemically stable will not only damage the pool equipment but will also ruin the interior finish of your Fibreliner™ Liner.
Remember: Chemical Abuse of the Pool's Surface VOIDS YOUR WARRANTY
Here are some helpful tips to maintaining proper water chemistry:
Chlorine Residual (Free Available Chlorine FAC) – 1.0 to 3.0 ppm
Proper pH Level - 7.2 to 7.6
Total Alkalinity – 120 to 150 ppm
Calcium Hardness – 350 to 400 ppm for chlorine
Cyanuric Acid (chlorine stabilizer) below 30 to 40 ppm
Metals – 0 ppm
Chemical abuse is considered to be any chemical levels that do not fall within the recommended ranges specified throughout the Use and Care Guide for an extended period of time.
Occasionally problems will occur. Your best approach is to bring a pool water sample to your local pool company for a complete water analysis. Below are some of the most common problems and their most likely solutions.
Probable Causes: Cloudy water is caused by any of, or a combination of the following conditions:
Likely Solutions: Check pH and adjust to between 7.2 to 7.6 (Ideal 7.4 to 7.6), Add shock, Check filter system for proper operation and circulation
Probable Causes: Most likely caused by algae growth.
Likely Solutions: Check and adjust pH and total alkalinity. Add shock, Follow up the next morning with a preventative dose of algaecide. If water does not start clearing in 24 hours, repeat treatment. Bring water sample to your local swimming pool company for a complete analysis.
Probable Causes: Low pH and/or Total Alkalinity. Possible waste build-up and formation of chloramines.
Likely Solutions: Check and adjust the pH and Total Alkalinity. Shock swimming pool water.
Probable Causes: Low stabilizer level and/or high chlorine demand from excess wastes in the pool water.
Likely Solutions: Take a pool water sample to your local swimming pool company for a complete water analysis. Make sure they test for stabilizer level and total dissolved solids and chlorine demand. Add chlorine stabilizer, other actions may also be required.
What is a Metal Stain?
Metal staining can occur on your Fibreliner™ surface. Stains may show up on the pool’s surface as small or large colored "splotches" or as overall "plating." Staining may occur quite suddenly or slowly over a period of months or even years.
What Causes Metal Staining?
Colored stains can be caused by the following:
The first line of defense is to always ensure that your chemical levels are in proper range:
A Metal Inhibitor product or Scale Inhibitor should be added after filling or topping off the pool water level, or after heavy rains.
Untreated water may stain your Fibreliner™ surface. For prevention use a Metal Inhibitor product or Scale Inhibitor. Follow manufacturer’s label directions for proper application.
NOTE: In many cases depending on the chemical manufacturer, there are different chemical product formulations for either prevention or removal. Make sure you are purchasing the best type of product for your needs. Consult East Coast Pools, Inc. or your local swimming pool company for additional information.
How do I know if the Stain is removable?
Get a small sample of pH lower (dry acid) and put in a white sock or use a couple of Vitamin C tablets. Place the powder or tablet directly over a small stain with the pool pump off. If the stain around the test area is removed within a couple hours, this indicates that the stain will likely respond to a Stain Removal product.
Follow label directions for Stain removal treatment amounts for existing stains. If possible, identify source of staining and follow prevention guidelines. After stains are gone, use a Metal Inhibitor product or Scale Inhibitor on a regular basis following manufacturer’s directions (especially after refilling, topping off, or heavy rains). Slowly bring chlorine level up to proper range (1.0 to 3.0 ppm). High chlorine levels or shocking the pool immediately after treatment may re-stain the surface.
There are also other possible causes for stains, such as stains caused by organics from plants and leaves. Such stains require a different treatment. Consult your local swimming pool company for further solutions.
