Water quality less than ideal: crystal clear but has odor common with high level of total dissolved solids in salt pools. High pH and high alkalinity along with relatively high total chlorine level and relatively low free chlorine level. Cyanuric acid and calcium hardness levels ideal, indicating likely no water loss present at this time, but with odor present recommend enzyme treatment to remove dissolved organic matter; should be done more frequently as pool not exceptionally large and with frequent use. Water quality will likely need those enzyme treatments and probably in the next 1 to 30 days organic matter treatments likely less than $100 but otherwise relatively good condition. No algae present on walls but some hidden behind tile between tile and fiberglass surface, relatively common in salt pools with high total dissolved solids issues. Mitigate by increasing pump run time, balancing chemical levels, and not letting them drop to zero in winter. Recommend another $100 in algae treatment starting with nonmetal algicide. Auto fill running at inspection—could be float trouble, set incorrectly, or potential water loss. Likely less than 10% chance of water loss due to water quality, but retest water quality in 1 to 30 days to confirm. Auto fill could be running to compensate for solar. Waterline tile on fiberglass pool is decoration glued on top of shell. Generally not much issue until year 10-20 when glue weakens and tiles come off; seeing some now likely due to salt pool causing additional issues especially where tile meets water through hot and cold temperatures. Tile currently in fair condition as organic matter growing behind tile visible due to glass tile; glue job C+ at best to B+ as tiles firm and strong but gaps present allowing algae on backside. Not major issue today but likely in next 5-15 years tile will need to be removed and re-glued; would not use glass tile again as calcium buildup difficult to remove without damaging it and ceramic may be more efficient but hard corners make reinstall challenging. Calcium present could be removed via tile cleaning service around $500 but water treatments would likely remove for less than $200 which may take up to six months. Appears mortar used instead of glue but in sections like above southwest light glue present behind tile indicating not enough mortar or incomplete waterproofing often only for aesthetics. Nothing needs to be done today but likely in next 5-15 years tile may require attention closer to five years if pool remains salt pool.
Estimated total: Enzyme/organic matter treatment less than $100 plus algae treatment $100 plus calcium removal less than $200.
