How long and how much biopellets do you run?

 

[Ponraj A]

I am running Bio pellets for 24X7 and running from the beginning of the tank for about 5 months now. It will be around 250gms inside.

I would just add a little more testing every few days

Hi Fish geek 88,

Thanks for your reply, you are in the mean that I have to add little more pellets ?

Hi Fish geek 88,

Yes. Overtime the bacteria will eat away at the pellets so you should be adding new ones every so often to supplement the loss anyways. If you are doing regular water changes and your nitrates are still fairly high then I would add additional pellets

Ok I will do so and thank you very much for your reply.

That sounds like a reasonable plan to me as well.

I have cleaned my Bio pellet reactor and added another 200gms to it. Will do the test after 3 days to have a check on the Nitrate stand.
