I’m trying to figure out the quality of my city’s water so I can gauge how much conditioner to use based off the sticky post on "Cost Effective Water Conditioners". These are the average levels found leaving the water distribution centres this past Sept 2013. I’m only going to list the ones i thought were important (if i'm missing something important lemme know).

pH - 7.58
Total alkalinity - 76 ppm (as CaCO3)
Total hardness - 83 ppm (as CaCO3)
Dissolved oxygen - 11.6 ppm
Fluoride - 0.66 ppm
Chloride - 18 ppm
Chlorine (free) - 0.75 ppm
Chlorine (total) - 0.96 ppm

I use Seachem prime which says to use 1mL per 10 gallon of water of tap water. Would i be able to use less? I want to see how long I can stretch a bottle for. I’ve been “overdosing” due to the fact that I add it into a 5 gallon bucket, and I can’t measure less than 1 mL.
 
Doesn't Seachem recommend the dosage base on the total gallons of your aquarium? You may not overdose after all...

i mean i'm basically adding double the dose in the 5 gallon bucket since i can't measure out 0.5 mL. I like to mix the prime with the tap water before adding to the aquarium. so if i change out 15 gallons of water, i have to dose for 30 gallons of water since i couldn't get a measurement that small. I'm getting a small syringe tomorrow so I can get those precise dosages. I was just wondering if i could be using less prime than the manufacturers suggestion, based on my cities water quality report.

is ~1 ppm Chlorine a lot?
 
5mL of Prime removes 5mg/L (ppm) of chlorine. So if your tap averages at 1ppm, you could technically use 1mL per 10 gallons. The ppm can fluctuate throughout the year though so it's probably safer to use at least 2-3mL. If you really want to stretch your dechlorinator I would switch to Seachem Safe when that bottle of prime runs out
 
Hello; Do a search using the key word "chemical water conditioners" alone or linked to my username. There have been several threads about using the various chemical water conditioners and using a storage method to control chlorine. You appear to be lucky in that your water system uses only chlorine.

While many are very strong in favoring the use of chemical conditioners, I have not had to for a few decades. I store tap water for a few days in containers. It is then is safe to use for water changes. There are some other advantages to this method on top of not having to buy chemicals.

As long as the tap water does not contain chloramines the storage method will work.
 
Ichecked the range of free chlorine and it ranges from 0.33 ppm to 1.43 ppm from 39 test points around the city.

What's the difference between prime and safe? Is safe more concentrated? How much safe would I have to use compared to prime?
