The Taylor K-2006C is a strong manual pool-water kit for an owner who will use FAS-DPD chlorine titration and the larger two-ounce reagents often enough to justify them. It is not automatically better than the smaller K-2006, and it does not include a salt test. The C changes reagent quantity, not the underlying test panel.
The kit covers free and combined chlorine, pH with acid/base demand, total alkalinity, calcium hardness and cyanuric acid. Its defining feature is FAS-DPD chlorine testing: add powder to make the sample pink, then count titrant drops until it turns colorless. This avoids matching close pink chlorine shades, but sample volume, drop technique, lighting, clean tubes and fresh reagents still matter.
This is a researched review, not a Smart Pool Care laboratory test. We reconciled Taylor’s kit literature and instructions with current retailer identity, long-term independent use coverage and 2026 test-kit comparisons. We did not buy, store, sample, titrate, compare, dose or own a K-2006C. No reading, treatment amount or water-safety conclusion is promised.
Quick decision card
| Need | K-2006C fit |
|---|---|
| Separate free and combined chlorine by titration | Core strength |
| pH, alkalinity, calcium hardness and CYA in one case | Included |
| Larger bottles for frequent testing | Choose C version |
| Light seasonal testing with minimal waste | Smaller K-2006 may fit better |
| Salt concentration for a saltwater generator | Choose/add a documented salt test |
| Instant app-connected result | No; manual drops and records |
| Medical or drinking-water certification | Not its purpose |
Verdict: buy K-2006C when a written schedule shows frequent testing will turn over two-ounce reagents while fresh. Choose K-2006 when storage time and lower test volume matter more. Either kit is only as good as sampling, instructions, reagent condition and the label-based treatment decision that follows.

K-2006C identity and boundaries
Taylor’s 2000-series literature distinguishes K-2006 from K-2006C by reagent size. Current exact-kit sources identify the standard K-2006 with 0.75-ounce bottles and the C version with two-ounce bottles. K-2006-SALT and K-2006C-SALT are separate variants that add salt testing.
| Model | Core panel | Reagent size | Salt test |
|---|---|---|---|
| K-2006 | FAS-DPD chlorine, pH, demand, TA, CH, CYA | 0.75 oz | No |
| K-2006C | Same core panel | 2 oz | No |
| K-2006-SALT | Core panel | Verify package | Yes |
| K-2006C-SALT | Core panel | 2 oz | Yes |
Do not confuse it with K-2005C, which uses a visual DPD chlorine comparator rather than the same FAS-DPD titration route. Also verify that a marketplace kit has not been opened, partially refilled, stored hot or assembled from mismatched reagents.
The Amazon link is an exact-name search because no direct ASIN was retained with adequate confidence in seller and reagent condition. Check seals, lot/date information where supplied, bottle labels, instructions, contents, seller, returns and storage history. Chemical age matters more than a polished listing photo.
What the panel tells you
| Test | Decision it informs | Important limit |
|---|---|---|
| Free chlorine | Current active sanitizer residual | Target depends on pool and CYA context |
| Combined chlorine | Indicates chloramine-related demand | Not a diagnosis by itself |
| pH | Comfort, sanitizer behavior and equipment balance | Color comparison and conditions matter |
| Total alkalinity | Buffering and pH management | Do not chase one number alone |
| Calcium hardness | Scaling/corrosion context | Fill water and pool finish matter |
| Cyanuric acid | Stabilizer context for outdoor chlorine | Dot-disappearance endpoint is subjective |
| Acid/base demand | Approximate adjustment planning | Volume and product label govern dosing |
The kit produces measurements, not a universal prescription. Chlorine targets differ with stabilizer, sanitizer system, local code, pool use, temperature and authoritative guidance. Calculate with an accurate pool volume and the current chemical label. Never add a product solely because a generic chart names one target.
Why FAS-DPD is useful
FAS-DPD replaces a close chlorine color match with a counted titration endpoint. Taylor’s procedure uses a defined sample volume, DPD powder and titrant. The result multiplier changes with sample volume and method. Copying a drop count from memory without confirming the current instruction can create a large error.
The endpoint is pink to colorless. A faint pink returning after the test sits is not necessarily the immediate endpoint described in the method. Follow Taylor’s current sequence, timing and mixing.
This helps separate free and combined chlorine and handle ranges beyond basic comparators, but it still requires detecting a color change. Anyone with vision or dexterity difficulty should test the procedure before depending on it. A magnetic stirrer can reduce manual swirling; it does not fix wrong volume, aged reagent or contaminated tubes.
Choose bottle size with a turnover worksheet
The C kit supplies substantially more reagent. That can reduce mid-season refills for frequent testers, but stored chemicals do not improve with age. Heat, sunlight, contamination and time can degrade them.
| Test | Planned frequency | Season weeks | Annual runs | Likely limiting reagent |
|---|---|---|---|---|
| Free/combined chlorine | ___ | ___ | ___ | Powder/titrant |
| pH | ___ | ___ | ___ | Indicator |
| Total alkalinity | ___ | ___ | ___ | Titrant |
| Calcium hardness | ___ | ___ | ___ | Titrant |
| CYA | ___ | ___ | ___ | CYA reagent |
Drop counts and bottle yields depend on the method. Do not rely on one universal “tests per bottle” number. If the smaller kit plus one fresh refill covers the schedule, that can be better than carrying every two-ounce bottle across several seasons.
Sample and technique checklist
Use Taylor’s current manual as authority. Collect a representative sample away from a return, feeder discharge, skimmer, surface film and recently added chemical. Use a clean tube and the exact marked volume.
Hold bottles as instructed so drops are consistent. Count carefully, mix between additions and read endpoints under suitable light. Rinse equipment appropriately and avoid cross-contamination between caps, bottles and cells. Record results with date, time, sample location, water condition and recent additions.
Repeat a surprising result before treatment. Check sample volume, reagent identity, storage, technique and interference notes. A second test made with the same mistake is not independent confirmation.
Storage and chemical safety
Test reagents are chemicals. Keep them in original labeled containers, tightly closed, upright, cool, dry and away from sun, heat, children, pets, food and pool-treatment products. Do not transfer reagents into drink or unmarked containers.
Never mix concentrates or return used material to a bottle. Follow Taylor’s safety data and local disposal rules. Wash after handling and respond to exposure according to label and poison-control guidance. The reagents test a sample; they are not added to the pool.
Treatment chemicals must stay separate from test reagents and one another. Never mix chlorine with acids, ammonia, other sanitizers or unknown residue. Use ventilation and protective equipment specified by each label.
K-2006C versus strips and digital testers
Strips are fast for screening, but broad color blocks provide less resolution for many dosing decisions. A digital photometer reduces some visual matching but adds calibration, cleanliness, battery, blanking and reagent requirements.
K-2006C’s strength is a documented manual panel with individual refillable reagents. Its weakness is time and technique. The best method is one the household performs correctly and consistently, with professional confirmation when results or conditions remain unclear.
Do not use any home kit to declare water safe after fecal contamination, a chemical spill, suspected pathogen event or other emergency. Follow public-health and qualified pool-professional guidance.
Final recommendation
Buy K-2006C when FAS-DPD chlorine detail and a full balance panel support frequent, disciplined testing and two-ounce bottles will be used while fresh. Buy K-2006 at lower volume. Add the salt variant only when the salt system requires it.
Before treating, verify the reading, pool volume, chemical label and interaction with existing balance. The kit improves decision inputs; it does not replace instructions, safety rules or judgment.
FAQ
What is the difference between K-2006 and K-2006C?
The core methods are the same; the C version uses two-ounce bottles instead of 0.75-ounce bottles.
Does K-2006C test salt?
No. Look for the explicitly named K-2006C-SALT or another documented salt test.
Does FAS-DPD avoid all color matching?
It replaces the chlorine shade comparator with a pink-to-colorless titration. The pH and CYA procedures still involve visual interpretation.
How long do reagents last?
Useful life depends on reagent, storage and manufacturer guidance. Check dates and instructions rather than assuming a fixed number of seasons.
Can the kit tell me exactly how much chemical to add?
It supplies results and demand tools. Accurate volume, product strength, label directions and full water context still determine treatment.
