Keep algae out of a water tank by blocking light, screening openings, limiting debris, maintaining turnover, cleaning sediment, and treating water as needed.

Seal a leaking water tank by locating the defect, lowering water safely, preparing the surface, and using a material-compatible fitting, weld, patch, or sealant.

Prevent tank algae by excluding sunlight, sealing and screening openings, reducing nutrients, removing sediment, maintaining turnover, and using suitable treatment.

Keep rain-barrel water fresher by excluding light, debris, insects, and animals; maintaining turnover and overflow; removing sediment; and cleaning routinely.

You cannot identify bacteria in water by sight, smell, taste, or a TDS meter. Learn how proper sampling and accredited microbial testing confirm contamination.

Unsafe drinking water may look, smell, or taste unusual, but many hazards are invisible. Learn why source assessment and accredited testing are essential.

Green growth in a water bottle may be algae or another biofilm and is not safe to judge by color alone. Discard the water, clean the bottle, and prevent recurrence.

A failing water tank may show cracks, bulging, corrosion, leaks, unstable supports, damaged fittings, or recurring contamination. Learn when to replace it.

Mosquito control for water tanks starts with sealed lids, fine screens, safe overflow, and no standing puddles. Use only treatments approved for the water's purpose.

The best epoxy for cracked plastic must bond to the exact resin and tolerate load, water, temperature, and movement. Some plastics need welding instead.
