Yes, I was just being cheap, I intend to buy it, the last total alkalinity was done using a 6-way kit from Walmart
hahahaha. that's awesome.. I am often called cheap, I prefer Frugal.

I'm going to postulate that you are being "frugal" right now. you could skimp by doing what you can, but at the end of the day, the TF-100 test kit will be one of the best investments you can make for your pool. It's actually more frugal in the long run to buy the kit than to try to skimp by. If you prevent one algae outbreak, the kit basically pays for itself.
have a read through this thread for some test-imonials...
I understand sticking with the status quo and harping on the tried and true. I still would like an answer to my question though.
The only things i need to test for are FC, CC, PH, TA, and CYA due to my pool type. The PH and TA should be sufficiently accurate with my current kit. The CYA is identical as far as I can tell. What i need better of is FC and CC.
Is it possible to just get the indicator powder and titrant for the FAS/DPD and that will give me the FC and CC answers I desire?
I DO intend to get a TFT-100-C at the beginning of the next pool season (if it is possible to wait). Budget is somewhat tight and the wife is complaining about all the spending already done (though the pool is mostly for her).

FAS/DPD Chlorine Test
More complicated, but gives a wider range, more precision, and also separately measures FC/CC.
1) Rinse and fill sample tube to 10ml mark.
2) Use teeny blue scooper (hold the flat end) to put one heaping scoop R-0870 powder into sample, swirl to mix. (OK if not all dissolves.) Sample should turn pink. If it "flashes" pink then the pink disappears, add more R-0870. If there's never a hint of pink at all, skip step 3; FC=0.
3) Add R-0871 one drop at a time, swirling the sample continuously, 1-2 sec between drops. Stop when sample turns colorless. Multiply #drops by 0.5 to get FC. (If it turns pink again after a few seconds, don't worry about it.)
4) Add 5 drops R-0003, swirl to mix. If it remains colorless, CC=0. If it turns pink, again add drops of R-0871 (swirling continuously) until it turns colorless. Multiply drops by 0.5 to get CC.
5) CC > 0.5 indicates a need to shock.
looks like I will need some R-0003 as well to do CC, but other than that, the HTH 6 way kit graduated cylinder has a 10 ml line. following the directions on the one page testing instructions page that is all i need (R-0870, R-0871, R-0003, and a way to measure out 10 ml)
Leslie pool store may be useless for some stuff, but they did seem to stock reagent refills. Gonna swing by there tomorrow and see if they have R-0871 and R-0003.

Must be a DPD test now (pink) instead of the OTO test (yellow)WTH??... That HTH indicator is different than mine. The chlorine used to be measured in grades of yellow and the PH in purple pink. Now they are both measured in pink?... Nothing like confusing everyone.
