You can try to increase the bacteria in your tank by having more area for them to multiply. The first thing I will tell you is to go to AngelsPlus.com and buy an "active sponge filter" that will come with bio established bacteria and will cycle your tank in no time. Plus by adding another sponge filter you will have more area for the BB colonies to grow.
While you wait for your wonderful life saving active filter, monitor your parameters every single day. And yes! You need to keep doing daily water changes to keep ammonia, nitrites and nitrates down, until you have more Beneficial Bacteria in your tank. Goldfish are messy fish, so 5 in a 10 gallon tank is going to be enough border line.
How exactly to I use the active sponge filter. Does it attach to my current filter?
Regardless, it looks like my tank has cycled itself again:
2 Molly's and 3 glofish (not goldfish) - maybe I got lucky!
Regardless, they are doing ok, but if this sponge filter will help, I am interested.
