Pete, I hate to have to keep asking questions, but my LFS owner is not very knowledgeable or willing to offer advice. Actually it was his advice I am asking about:

As stated earlier, I have a Fluval 404 Canister. It has 8 tray’s to place filter media in. When I first cycled my tank, I used what came with the filter: the bottom 2 trays (four compartments) had a bag of carbon in them each. The top 2 trays (four compartments) had bio rings in them.

My system had cycled and been running for about 10 weeks when I ordered my horses. I asked the LFS owner if I needed to change any media since it was 10 weeks old and he had me do the following:

1) Clean the entrance sponges thoroughly under tap water and then put back in the canister.

2) He had me replace all 4 bags of carbon with fresh ones.

3) He told me to throw away the 4 trays of bio rings and replace them with 2 trays of Nitrate remover (De-Nitrate) by Seachem, and put Fluval water polishing pads in the top 2 trays. However, my Nitrates are still high at 10 ppm, yet the nitrites are 0??? How do I lower the nitrates to zero???

I was against the change, but told me that I didn’t need the other stuff because I had live rock. That is when my ponies arrived and it all went bad. Thank God my quarantine tank is fully cycled with a filter and skimmer. Can you PLEASE tell me what to fill my canister with??

Will it take another 8 weeks to cycle?

Please help and thanks for sharing your knowledge. Because of this, I will ALWAYS buy from you guys.
