Dogs and Your Frisco Pool — What Pet Owners Need to Know
One dog equals 3-5 swimmers in chlorine demand, triples filter cleaning frequency, and scratches plaster with every entry. Here's what pet swimming does to your chemistry, filter, and surfaces — and how to manage it.
Your new pool's first summer requires more attention than any other season — fresh plaster spikes pH daily for 6-12 months, pump runtime needs to increase from 6 hours to 10-12 hours, water features drive pH up constantly through aeration, and salt cells need output increased from 40% to 60-80%. The builder's 10-minute orientation covered about 20% of what you need to know. The other 80% determines whether your first summer is enjoyable or a $500+ series of preventable problems.
Here are the specific first-summer challenges that Frisco pool owners face and how to handle each one before it becomes an expensive lesson.
The Plaster Is Still Curing
If your pool was plastered within the last 12 months, the plaster is still curing. New plaster releases calcium hydroxide into the water for 6-12 months after application. This creates specific challenges during your first summer:
pH spikes daily. Fresh plaster off-gasses calcium hydroxide which is highly alkaline. Your pH will drift to 8.0+ within 24-48 hours of adjustment. During the first summer, plan on adding muriatic acid 2-3 times per week — not the once-a-week the builder implied.
Calcium hardness climbs fast. The calcium released from curing plaster adds to the water's calcium hardness independently of your fill water. You may reach 400+ ppm calcium by midsummer even if you started with 200 ppm fill water. Test monthly and plan a partial drain in fall if calcium gets above 450 ppm.
Brushing is critical — and you're probably not doing enough. The builder said "brush once a week." During the first summer, brush every 2-3 days. New plaster develops hydration marks (discolored spots) if it's not brushed frequently during the curing period. These marks are permanent if they set. Aggressive brushing during the first year prevents them.
Don't acid wash the plaster in the first year. Some new owners see staining or discoloration and want an acid wash. Acid washing new plaster can damage the surface before it's fully cured. Wait at least 12 months before considering acid treatment.
Your First Algae Scare
It will happen. Probably in June or July. You'll walk out to the pool one morning and the water has a slight green tint or a haze that wasn't there yesterday. Don't panic — this is normal for first-summer pools and fixable in 24-48 hours if caught early.
Why it happens: New pool owners are still learning their pool's chemistry rhythm. The chlorine demand changes as summer heat increases — what worked in April (1 gallon of chlorine per week) isn't enough in July (2-3 gallons per week). The first time the demand exceeds your dosing, algae establishes.
What to do:
- Test free chlorine — it'll be at 0-1 ppm
- Shock with 2 gallons of liquid chlorine (for a 15,000-gallon pool)
- Brush all surfaces
- Run the pump 24/7 until clear
- Clean the filter within 24 hours of shocking
What to learn from it: Your summer chlorine dosing needs to increase. If you're on weekly service, tell your technician the pool hazed — they'll adjust the chlorine dose for the hotter months.
The Pump Schedule Needs to Change
The builder probably set your pump to run 6-8 hours per day. That was fine for winter and spring. In a Frisco summer, 6 hours isn't enough.
Summer pump schedule: 10-12 hours per day minimum. The pool needs to turn over its full volume at least once every 24 hours, and in summer the increased biological activity, higher temperatures, and greater swimmer load demand more filtration.
If you have a variable speed pump (most new pools do):
| Time | Speed | Purpose |
|---|---|---|
| 6 AM - 10 AM | Low (1,200 RPM) | Overnight circulation |
| 10 AM - 6 PM | Medium (2,000-2,500 RPM) | Peak UV/heat hours — needs stronger flow |
| 6 PM - 10 PM | Low (1,200 RPM) | Evening circulation |
| 10 PM - 6 AM | Off or very low (800 RPM) | Energy savings |
Total runtime: 12-16 hours with variable speed scheduling
Cost: A variable speed pump running 14 hours/day costs $20-35/month in electricity. A single-speed pump running 10 hours/day costs $50-70/month. If your builder installed a single-speed pump (rare in new Frisco builds, but it happens), start planning a VSP upgrade — it pays for itself in 18-24 months.
The Water Features Are Messing With Your pH
Your new pool probably has water features — a spillover spa, sheer descent waterfall, bubblers, or deck jets. They look great. They also aerate the water constantly, which strips CO2 and drives pH up.
The more your water features run, the faster pH rises. If your spa spillover runs 10 hours per day, your pH management is dramatically more demanding than a pool without water features. You may need acid additions every 2-3 days instead of weekly.
The solution options:
-
Run water features only when you're using the pool. Put them on a manual switch or automation schedule so they're off during unattended hours. This reduces aeration and slows pH drift.
-
Accept higher acid consumption. If you want the features running all day, budget for 1-2 gallons of muriatic acid per week instead of the 1 cup per week the builder implied.
-
Lower your alkalinity target. Keep total alkalinity at 60-80 ppm (lower than the generic 80-120 recommendation). Lower alkalinity means pH rises more slowly between acid additions. This is the approach we use on every pool with active water features in Frisco.
The Salt System Needs Attention
If your pool has a salt chlorine generator (most new Frisco builds do), the first summer is when you learn that "hands-free chlorine" isn't actually hands-free.
The cell output needs increasing. The builder set the output at 40-50% for winter. In summer, chlorine demand doubles or triples. You'll need to increase output to 60-80% — check the cell controller and adjust.
The salt level drops. Splash-out from swimming, backwash water loss, and rain dilution all reduce salt concentration. By midsummer, your salt level may have dropped from 3,200 ppm to 2,800 ppm. The cell will show a "low salt" warning. Add pool-grade salt — typically 40-80 pounds for a 15,000-gallon pool to raise the level 200-400 ppm.
The cell is already scaling. In Frisco's hard water, calcium scale builds on salt cell plates from day one. By the end of your first summer, the cell needs its first cleaning. Don't wait for an error code — schedule a visual inspection and acid cleaning at the end of your first summer to establish a quarterly cleaning routine.
Your Filter Will Need Cleaning Sooner Than You Think
The builder may have said "clean the filter every 3-6 months." In Frisco's first summer — with pollen, construction dust (if your neighborhood is still developing), and the increased debris load from daily swimming — your filter needs cleaning every 2-4 weeks.
Watch the pressure gauge. Your filter has a pressure gauge on top. When the filter is clean, note the pressure (typically 8-12 PSI for a clean cartridge). When the pressure rises 8-10 PSI above the clean baseline, the filter needs cleaning. Don't wait for the filter to stop flowing — by then it's overloaded and the water is already clouding.
The Biggest First-Summer Mistake
Going on vacation without pool service.
Every summer, first-year pool owners take a week or two-week vacation in June or July. They figure the pool will be fine — the pump is on a timer, the salt cell is making chlorine, what could go wrong?
What goes wrong: the chlorine demand in 100°F heat exceeds the salt cell output, the pH drifts to 8.0 without acid additions, a storm dumps debris that nobody removes, the filter loads without cleaning, and the pool goes green. They come home to a swamp.
If you're going on vacation during your first summer, hire a pool service for the weeks you're away. Even if you maintain the pool yourself the rest of the year, vacation weeks need professional coverage. The cost of 2 weeks of service ($90-100) is a fraction of the $300-500 green pool recovery that results from no service.
