  1. Fertilizers and Water Parameters
    It’s sounds contradictory since it removes both solid and non solid waste, but I thought I heard it’s a lot better than carbon and does not remove certain fertilizers (iron pops to mind, KG etc) let me know your thoughts
  2. Fertilizers and Water Parameters
    Has anyone had an iron smell or rust when recharging Purigen before? I'm assuming the Purigen shouldn't be used again but I'd really like to figure out what went wrong. I have some 100 ml bags of Purigen I recharged 3-4 days ago. This was it's third recharge. After the bleach solution (1 cup...

    I'm hopeful those of you with more experience with Purigen will weigh in. The instructions that come with Purigen now detail a 3-step process to recharge it. First, a 24-hr 1:1 bleach/water soak, Second, an 8-hr soak in 4T Prime @cup water mix (wow that is a lot of Prime), and lastly, a soak in...

    I have moved old jewel filter media into a new external filter that uses ceramics - how long do you think I should leave the old media in before removing it to establish a colony in the new media? (100litre tank, fully stocked). Also, does anyone know how the use of seachem purigen would...

    I just received my Catappa Leaves and I want to use them in my 75 gallon OEBT/RCS tank. I run purigen in this tank. I know purigen removes all the tannins from the water. One of the benefits from the Catappa leaves comes from the tannins from what I've read. What I don't know is if ALL the...

    I purchased a 100 mL box of Purigen for my tanks. Since this is the first time I've used this, I didn't realize it was all in a single sealed mesh bag. I have a few nano tanks I'd like to use this in, but obviously this size is too large for the majority of my filters. I'd like to make smaller...

    In starting up a new tank does the addition of Prime or Purigen (in the filter) do anything to slow the cycling of the tank? Do they make the cycling unnecessary? (Dumb question, probably!) Both are said the either detoxify/neutralize or remove ammonia, nitrites and maybe even nitrates. Any...

    Here's a new one for you guys.... Is it possible to destroy Purigen by leaving it in the 50/50 bleach/water solution for too long? This is why I ask: I went and set a pouch of Purigen in the recommended 50/50 solution sometime right before Christmas. I placed it up on a high shelf (primarily...

    Hello I have a 250ml bottle of seachem purigen and was wondering how much of it I should use for a 30 litre tank? I have the chemi bag and stuff but im not sure because on the bottle it says 250ml treats 250gallons which means I should technically do 1ml of powder per 4 litres (this is hardly...
