I'm buying my bettas new 7.4 gallon today, and I just wanted to see if I was setting things up right.
I plan on having a couple of kgs of sand and some silk plants. I plan to thoughraly wash out the sand using buckets/hose, then place it in the tank. When it comes to water, I was thinking of putting some of the filter sponge from my Biorb (my bettas current tank) in with the new filter sponge for the new filter to kick start the bacteria colony and possibly some of the biorb ceramic media too. I've got a bottle of bacteria boosting stuff that I was also going to put in there. Don't worry, I'll condition the water too.
My question is when I can add my fish (I may be getting some shrimp too, when should these be added?). Obviously, there will already be a bacteria colony growing in there from the bacteria booster & biorb media, so will it be safe for him after just a few days or so to let the bacteria grow a little more and allow the tank to settle down? I don't want any ammonia spikes etc, but equally I don't have the money at the moment to buy a proper testing kit (about £30, or just short of $50 in the UK).
