Purigen in planted aquarium

[dano1677]

I haven't seen any information concerning adding Purigen in a seeded tank. So my question is when is it safe to change out my carbon for Purigen. -- My tank (freshwater 50 gallon) had been up and running for a year with two Emperor filters. Last week I gutted the aquarium, added 2 inches of flourite, and one inch of heavily washed play sand, and planted approx. 8 plants. I also upgraded my filtration to a Filstar Large canister. I had cut up a sponge that was in my HOB filter and placed it in my biomedia tray. I also re-dosed the aquarium with tetra safe start. My main concern would be hampering my BB by placing the Purigen in the filter. Should this concern me?

Shouldn't be a concern at all.

I've used Purigen 24/7 for 3 years now in my planted discus tank, and have never seen/had any evidence of Purigen negatively affecting the BB. There should be no problem whenever you decide to place it in your filter.

Be aware that your tank is likely going to re-cycle.

I won't run my tanks without it

I doubt it, the poster said they used safe start, which is the new bio spira product... I have successfully used this a bunch of times now and avoided the cycle, sort of expensive but worth it IMO!

I added the Purigen about 4 days ago, my water parameters have remained solid. My water clarity has vastly improved. So far I'm highly impressed by Purigen.

I think he/she is referring to the fact that the OP completely gutted the aquarium. In a sense this would be true if the OP had not used the old sponge and tetra safe start. With these two, it should be enough to keep the tank stable.

Purigen works great in any tank. Doesn't seem to have any negative side effects. Definitely better than charcoal/carbon. I have it in my 5gal planted and it's never been cloudy! I have some in my 210gal as well. I plan to get some for my 5gal pico sw tank too. Keeps the tank insanely clear and polished! This stuff is truly "magic beans".
