    thanks Inwall, thats good advice can you expand on that please
    what would be the wrong type and why would this result in poisoning

    I chose not to do that, I doubled the rinsing and soaking in freshwater and then left it on the balcony to air dry and bake for a few days

    Sure. In a nutshell, some chlorine removers only TEMPORARILY bind chlorine and they include a slime coat so the fish doesn't absorb the chlorine when those bonds break down. The slime coat in these products will ruin the Purigen forever. Additionally, the amines will combine with the chlorine in the bleach and create chloramines.

    It's not a problem....just use Prime.

    Anyone know if this stuff affects phosphate levels as well?

    I dont believe it is effective for Phosphates greysoul
    having just checked the packaging it does not indicate it is
    its states Ammonia, Nitrite and Nitrates
    naturally as some nitrate does become phosphate , removing nitrate
    does prevent that occuring

    but if your looking to reduce an existing Phosphate level
    then an alternative chemical media is your best option

    I would just buy a new batch, rather than risk my tank getting poisoned!

    Yeah I am not so sure on regenerating it. I wouldn't want to take that risk. Overall sounds like a good product though.

    Using the Seachem Prime as directed will take care of all concerns.

    The fact that you can regenerate the product is one of the main reasons why I used to use it. Why spend money on new unless you have to. And bleach does dissipate if given enough time between using it and placing whatever was soaked in it back into your tank..

    +1 on this

    I purchased spares

    in the 5ft its lasting 10 weeks or so , and when my nitrates start to show (weekly testing) at 2.5ppm , thats when I remove the Purigen and replaced with a bag that has been bleached, rinsed, soaked and then sat on my balcony for 10 weeks or more , so plenty of time for bleach to oxidise?
