Why algaecide matters for Justin pools

Algae isn't just ugly — once it takes hold, it consumes chlorine 10× faster than clean water, wasting your sanitizer budget and giving you chloramines, cloudy water, and staining. The right algaecide prevents the bloom in the first place (polyquat, weekly dose), kills an existing bloom (copper-based, one-time shock), and removes the phosphates algae eat to grow back. DFW summers are prime algae season — a $15 bottle of algaecide saves a $300 green-to-clean service.

Justin features a mix of water sources depending on neighborhood. Newer master-planned communities are served by municipal water systems with good chemistry (typically 300-400 ppm TDS). Older ranch properties and some established residential areas rely on well water with elevated mineral content (600-1000 ppm TDS), particularly iron and calcium. New construction pools benefit from starting with balanced chemical profiles from the groundup, while older wells in the area create challenges similar to Argyle requiring chelating agents and careful pH management. Understanding each property's water source is critical for delivering appropriate service.

Algaecide questions from Justin customers

Why does algae keep coming back in Justin pools?
Three usual culprits in Justin: (1) low free chlorine at night (below 1 ppm lets spores establish), (2) phosphates above 300 ppb feeding regrowth, and (3) iron and other metals in well water that react with chlorine and leave less sanitizer to kill algae. Fix those three and algae doesn't recur. We sell all the diagnostic tools and the fixes — bring a sample to our Northlake store for a free test.
Best algaecide for a Justin pool?
For weekly prevention in Justin, polyquat 60 (copper-free) is our default — it doesn't stain plaster, it's safe for salt cells, and it's one bottle a month for an average pool. Many Justin pools run salt chlorine generators, which changes how we dose the other chemicals. On well-water pools, we avoid copper-based algaecides entirely — your water already has metals that can stain plaster, and copper adds to the problem. Stick to polyquat + phosphate remover.
Do I need a phosphate remover for my Justin pool?
If you've had two algae blooms in the last year, yes. Phosphates are algae food — under 100 ppb is ideal; above 500 ppb, no amount of chlorine keeps algae out. DFW rain, lawn-fertilizer runoff, and leaves all contribute phosphates. PhosFREE from Natural Chemistry drops levels to near-zero in 48 hours. We include a free phosphate test with any chemical purchase at our Northlake store or delivered to Justin.
Can you deliver algaecide same-day to Justin if my pool's already turning?
Yes — and time matters. Every hour of full sun on a borderline-green pool doubles the problem. Order by 2 PM Central weekdays and we deliver same-day from the Northlake store. Call (469) 455-1054 before 2 PM and we can have a driver to Justin (76247) with polyquat, a metal sequestrant, and shock on board — everything to stop the bloom in one delivery.
Polyquat vs copper algaecide — which do I use?
Polyquat 60: weekly preventative, doesn't stain, safe for salt pools. Copper-based: kills existing algae fast, but can stain plaster and hair if overdosed — use as one-time knockdown only, not weekly. Rule of thumb: polyquat weekly, copper only when you see an active bloom.
Can I swim after adding algaecide?
Polyquat: 15 minutes. Copper-based: 15 minutes but avoid swimming within 48 hours of a metal shock (staining risk on wet skin/hair). Wait for the pump to circulate fully (one full turnover) before entering.
