Chemipure does remove phospates so if you require phospate buffering to keep your PH up Chemipure is a no goBeen doing a little reading on both products are they as good as advised (water clarity and nitrate lowering) ? which is better ? both state around 6 months of use is it sort of true? can either be used while cycling ?
Purigen is fantastic, works very well but ONLY when used in conjunction with carbon as purigen kinda takes up where carbon leaves off.
6 months ? Pfffffttttt .... 2-3 months at best and re-charge ? pffffttttt ... re-charging works yes ...but only once or twice and each time you lose 50% effectiveness (ie: first use 2 months , re-charge 1 month another re-charge only 2 weeks)
That said ...
Purigen is my single greatest expense in fishkeeping.
It is that good.
