Beneficial Bacteria (BB) colonizes in the places where they can feed on the stuff in the water they like the most, like in the filter pad where the water is circulated through. You can add an additional filter pad if it is a hang on the back filter (hob
) and piggyback them together. This gives even more good surface area to the BB to grow as much as possible to help break down waste in the tank.
So also as a side note, don't ever clean the filter pad in tap water because the chemicals in the water will kill bacteria. So use old partial water change (pwc
) water for the heavy dirt and swish it around, then I use fresh treated water in the bucket to clean more... more swishing and then back to the filter.
You do not need to replace the filter until it is falling apart. I also use 2 filter pad inserts, cleanest one in the front closest to where the water exits the hob
. Replace only one pad at a time when needed. To keep your BB as plentiful as possible.
Do huge pwc
, or back to back ones... one after the other or one at night and one in the morning. Just because the fish don't die doesn't mean they aren't being harmed.
Prime water conditioner will be a big help to your fish care it helps neutralize some of the toxic effects of the Ammonia, Nitrite and Nitrate. Not a replacement for clean safe water. You can read about it on their website.
