no offense taken and my examples are provided to be honest about my poor practices and
to share some experience that doesn't exactly agree with the status quo
I do not recommend others follow poor water change schedules
a 40% change two to four times a month as recommended is hardly poor practice
We tend to disagree on most topics and your opinions are as valued as any
I truely doubt however that over filtration is a common newcomer methodology as you suggest
the BB colonys do not live in the water column and are not damaged by these WC schedules
It just starves the colony of food
A tank void of ammonia due to over zealous water change practices
will never establish a colony large enough to deal with any change in bioload
whether that be the addition of new fish or an entire can of food dumped in at once
It stays clean because you clean it, not because of the filtration
An estabilshed aquarium reaches a sort of ecological equilibrium if you will
where the plants animals and microbs work together to stabilize the water conditions
The tank's balance/stability in this example was very delicate and completly disrupted by a simple overfeeding
I believe a 4yo tank should have turned an overfeeding into Nitrates in 24-36 hours
and an 40% WC should have closed the deal
There is talk in the repost about wat killed off the colony allowing ammonia to be present
The BB didn't die off, they were never estabilshed to a sufficient level due to lack of food
OP is looking for a solution to the current symptoms which you provide
once this issue has been resolved I hope you consider my recommendations
to prevent the problem from ever happening again
