Serving Murfreesboro, Franklin, Smyrna, Arrington, and College Grov
If you pulled the cover off your pool this spring and found something that looks more like a pond than a swimming pool, you're in good company. Green pool calls spike every year right around the time Middle Tennessee homeowners are ready to start swimming — and it's almost always fixable, faster than you'd expect.
At ASP — America's Swimming Pool Company of Murfreesboro, our Green to Clean service is designed specifically for this situation. Here's everything you need to know.
Why Did My Pool Turn Green?
A green pool is almost always an algae problem. Algae is opportunistic — it moves in fast when conditions are right, and Middle Tennessee gives it plenty of opportunities:
- Winter neglect or an extended off-season — pools that sat untreated through fall and winter are the most common green pool calls we see in the spring
- Low chlorine levels — without consistent chemical maintenance, chlorine drops and algae takes over quickly
- Poor circulation — if the pump hasn't been running regularly, stagnant water is an open invitation
- Heavy rain or spring storms — rainfall dilutes your water chemistry and introduces phosphates that feed algae growth
- Warm spring temperatures — algae blooms fast once the water warms up, especially if the chemistry isn't dialed in
Whether your pool is in Murfreesboro, Franklin, Smyrna, Arrington, or College Grove, the story tends to be the same: it looked fine when you closed it in October, and by April it's a different story.
Is It Safe to Swim in a Green Pool?
No — and this is important. While the algae itself may not be the biggest concern, green water almost always comes with bacteria and other pathogens you can't see. Keep the family out until the water has been tested, treated, and cleared.
What Is a Green to Clean Service?
Our Green to Clean service is a systematic, chemistry-driven pool recovery — not a quick chemical dump. Our CPO-certified technicians follow a proven process to take your pool from green and unsafe back to crystal-clear and swim-ready:
1. Water Testing & Assessment We test your water first — pH, chlorine, alkalinity, cyanuric acid, and phosphates. That tells us exactly what's driving the problem and what it will take to fix it for your specific pool.
2. Algae Treatment & Super Chlorination We apply professional-grade algaecide and a high-dose shock treatment to kill active algae and the spores that would cause it to come right back.
3. Brushing Every wall, step, and floor surface gets scrubbed down to break up the algae biofilm and allow chemicals to fully penetrate all surfaces.
4. Vacuuming to Waste Dead algae and sediment are vacuumed directly out of the pool — routed to waste rather than through the filter so your filtration system doesn't get overwhelmed.
5. Filter Service We clean and backwash your filter so it's ready to handle the load of clearing the water after treatment.
6. Chemistry Restoration & Follow-Up We balance your water chemistry and schedule a follow-up to confirm the pool has fully recovered.
How Long Does It Take?
It depends on how far gone the pool is:
- Level 1 (light green, recent onset): Most pools are swim-ready in 24 to 48 hours
- Level 2–3 (heavy algae, extended neglect): Recovery typically takes 3 to 5 days
You'll almost always see a noticeable improvement after the first treatment — it just may take a follow-up visit or two to get it fully clear.
Do You Have to Drain the Pool?
In most cases — no. Draining is rarely the right first move, and it's often unnecessary. Our Green to Clean process restores your existing water in place, which saves you money and keeps the process simpler.
For pools that have been sitting completely untreated for multiple seasons, we may recommend an acid wash or a more thorough equipment inspection — and we'll walk you through that honestly if it applies. Unlike the Florida Gulf Coast where high water tables make draining risky, Tennessee pools can be drained more safely when truly needed. But it's still a last resort, not a first step, because restoring the water is almost always less expensive for the homeowner.
How Do I Keep My Pool From Turning Green Again?
The best defense against a green pool is consistent maintenance through the whole season:
- Weekly professional service from spring through fall
- Running your pump at least 8 hours per day
- Regular water chemistry testing
- Keeping your filter clean and functioning
- Starting the season early — don't wait until the water is already warm to open up
Homeowners on our regular weekly maintenance program rarely call us for a Green to Clean, because the chemistry stays balanced before algae ever gets a foothold.
