Smokey Water After Adding Purigen To A Cycled Tank.

[AlphaNoob]

Hi.

I have an established 180 ltr jewel rio tank. It has been cyled for a good few months now. I recently added a 100g packet of Purigen to my filter(fluval 206)and I now get very cloudy water. I just did a 60% water change and it cleared up but after 24Hrs you can barely make out the back of the tank. I at first thought it was an ammonia spkie from cleaning the filter on the last water change but the tests were Amm. 0 Nitrites 0 Nitrates 0-10 pH 7.6ish. I also recently added a small 9w uv filter because where the aquarium is situated it gets a lot of natural light so I was getting green water. I have a theory that the Purigen is absorbing most of the nitrogenous waste and thefore the bacterial colony that I had, have a significant loss of food and are dying off. Any ideas would be greatly appreciated.

Purigen has an affinity to N03 particularly, it doesn't directly effect the A and N bacs. It won't adsorb ammonia directly. Did you remove any other media to fit the Purigen in?

It sounds like a bac bloom to me...

It replaced a carbon bag in the top tray. If it has an afinity for NO3 then my plants probably wont like that!
I have just noticed some of the fish might have a touch of white spot. Parameters are OK so hopefully just stress from the increased water changes (did a 90% over the weekend), anyway Purigen is out whilst I am medicating with Esha Exit and 2000.

it has an affinity for organic N03, SO if your dosing KN03, it will leave this alone.
