Weekly Summer Maintenance:
- To start, add Pooltec "clean" dosage to balance pool water. This product must be used with a registered sanitizer.
- Thereafter, add "weekly maintenance" dosage - use higher dosage for algae prone or heavily used pools.
Algae Cleanup:
- To start, pools containing heavy algae growth should be cleaned of excess debris.
- Super-chlorinating pool water and adjusting water pH will help improve cleanup.
- To kill green or yellow (mustard) algae, add Pooltec "visible algae" dosage. Use higher dosage for heavier algae growths.
- It is important to brush algae clinging to surfaces.
- To kill black algae, add the maximum Pooltec "visible algae" dosage. Use a combo or wire brush. Frequently scrub growth for 7 - 10 days until eradicated. Use "weekly maintenance" dosage after the cleanup period. Broadcasting granular chlorine over affected area can further help penetrate and kill the growth.
- Increase pump circulation time during cleanup period.
