I have a spare bag of Purigen so when it is time fore a regen I just swap bags in the canister - this gives me plenty of time (weeks) to do the Purigen regenerate.

 

I have been following the Seachem guidelines.

1. Bleach 1:1 for 24 hrs
2. rinse well - I do it over several days actually
3. Prime 4 tablespoons / cup for 8 hours (55ml / 250ml)
4. rinse well
5. store - keep moist (I actually store it in a small jar of water, then rinse well before use)

 

so, my question is if you do the step 2 rinse for an extended time what is step 3 with the Prime doing?

and can it be eliminated?

is there any test I can do before and after the Prime step that can indicate what it is achieving?

I have used Purigen for more than 10 years, and have NEVER found it necessary to employ a dechlorinator. A bit of common sense is all that is necessary, and prolonged washing and rinsing will ensure that all chlorine is eliminated. It is a good idea to have spare bags, and to alternate them. The rinse step prior to using a stored bag is necessary, since the resin hydrolyses to a small extent, and in so doing releases some ammonia.

 

If you wish to check on chlorine presence before and after the unnecessary dechlorinator step, just use a pool chlorine test, Any positive result will indicate that further treatment (rinsing) is required.

that sounds like a good answer

ok. got some pool strip tests that measure:

• total hardness
• total chlorine
• total bromine
• free chlorine
• pH
• total alkalinity
• cyanuric acid

 

did some tests on my:

• stored regen'd Purigen water jar
• tap water
• aged water reservoir/tank
• mature aquarium (Tropheus tank)

 

hardness, pH and alkalinity were all were I expected them for the treated and untreated water (tap and purigen jar).

treatment is with Seachem Salts & Tang Buffer.

 

chlorine, bromine and free chlorine all measured zero.

when I rinse the Purigen the water is getting aerated a lot, and it has had a lot of rinses since the bleaching, so that makes sense,

but was expecting the tap water to measure something?

 

the cyanuric acid was similar for all, 30-50 ppm, except for the aged water which was higher at 100ppm. the Tropheus tank might have been marginally higher than the 30-50ppm. Is this saying the salts and buffers affect this reading and the nitrates and bacteria in the aquarium tank lessen it?
