Pool Water Chemistry 101: Ideal Levels for North Texas Pools
Chlorine, pH, alkalinity, calcium, cyanuric acid. Here is what each number should be for a North Texas pool, why our mineral-rich fill water changes the math, and how to keep it balanced.
Find the water loss before it hurts your pool or your yard.
Or book weekly service online, no card neededEvery pool gives up a little water to evaporation, but a real leak wastes water, throws your chemistry off, runs your bill up, and can wash out the soil around the shell and the equipment pad. If your water is dropping faster than evaporation explains, we’ll find where it’s going and tell you what fixing it takes.

We start with a bucket test to rule out plain evaporation, which in a Texas summer takes more than folks expect.
Pressure testing on the plumbing and dye testing at the shell and fittings narrow down where the water is actually getting out.
Once we find it, we explain the cause and your real options, so you can decide with the whole picture in front of you.
True Texan Pools keeps your water swim-ready all year, across Plano and the rest of DFW. Clear pricing, a photo report after every visit, and Austin doing every job himself.
A simple bucket test tells you a lot: float a bucket of pool water on a step and mark both levels. If the pool drops noticeably faster than the bucket over a day or two, you likely have a leak rather than just evaporation.
More than people expect. An eighth to a quarter inch a day is typical, but a hot, dry, windy Texas summer day can take half an inch on its own, and local utilities quote about that as the summer average. So a quarter inch is not the ceiling. Consistent loss well beyond half an inch a day, especially if your chemistry keeps drifting or the ground stays wet, is what points to a leak worth investigating. The bucket test is the reliable check, because it measures your pool’s evaporation on the same day under the same conditions.
We use a combination of bucket testing, pressure testing of the plumbing lines, and dye testing at the shell and fittings to isolate whether the leak is in the structure, the plumbing, or the equipment.
