Recovery Or Drain: The Decision
Draining a green pool looks like the obvious answer and is usually the wrong one here. Much of Pinellas sits on a high water table, and an empty shell has nothing inside it to resist the pressure pushing up from below. Pools do float. When they do, the damage is structural and the bill stops being about cleaning.
Recovery through filtration and chemistry avoids that entirely, and for the large majority of pools it works. The cases where draining genuinely is the answer — a pool that has been standing for years, one contaminated beyond what treatment can address, or one already scheduled for resurfacing — are the exception, and they are handled with the water table specifically in mind.
What Actually Happens
Recovery is not one dramatic treatment. It is a sequence, and the filter does most of the work. The chemistry kills the algae; the filter has to physically remove what is left, and that is limited by turnover — how many times a day the system can move the whole volume of the pool through the media.
So the first step is the equipment, not the chemicals. A filter that needs cleaning or media replacement will double the timeline, and a pump that is already struggling may not survive several days of continuous running. We look at that before quoting a recovery, because the alternative is discovering it on day three with the pool half cleared.
When An Acid Wash Is Required
A pool that has been green for a long time often clears to reveal staining underneath — organic shadows in the plaster where algae was attached, sometimes in a distinct tide line. Chemistry will not lift those, because they are in the surface rather than on it.
An acid wash takes off a thin layer of plaster and the staining with it. It genuinely resets the look of a tired surface. It also consumes surface material that does not come back, so a pool can only take a limited number over its life, and one that has already had several is closer to needing resurfacing than to needing another wash. We will tell you where yours sits.
Stopping It Happening Again
A pool turns green for one of three reasons: circulation stopped, chemistry drifted, or nobody looked at it for a few weeks in summer. The first is a repair, the second is a routine, and the third is a service plan. Recovery that does not identify which one it was is a treatment you will be buying again next year.
Frequently Asked Questions
How long does it take to clear a green pool?
Most pools clear in three to five days. A pool that is green but still translucent often turns in forty-eight hours. One you cannot see the first step in takes longer, because the filter has to physically remove everything the treatment kills, and that is limited by how fast the system can turn the water over.
Why not just drain it and start fresh?
Because in Florida an empty pool can float. The water table across much of Pinellas sits high enough that hydrostatic pressure under an emptied shell can lift or crack it, and that turns a cleaning bill into a structural one. Draining is sometimes the right answer, but it is a decision with real consequences, not a shortcut.
What is an acid wash and does my pool need one?
It removes a thin layer of the plaster surface, taking staining with it. It is the answer when a pool has been green long enough to leave organic shadows that chemistry will not lift. It is not the answer for a pool that is simply cloudy, and each wash costs the surface material it can never get back — so it is used when needed, not routinely.
Will the equipment survive it?
That is the part most quotes ignore. Recovery leans hard on the pump and the filter for several days continuously, and a system already near the end of its life often fails in the middle of it. We check the equipment before starting, so you can decide knowingly rather than be surprised halfway through.
Can you keep it clear afterwards?
Yes, and honestly this is the part that matters. A pool goes green because something stopped happening — circulation, chemistry or attention. Recovery without fixing that just means doing it again next season, so we will tell you which of the three it was.
