Argh. If you say so... Tomorrow I will purchase a small 125 gallon
tank and place the fish into it.. being Saturday with no work.

I have 3 fish with broken backs now. what can I do to help?
injections?

Finally: The pond water seems to be quite foamy now. Is this the
aerobic bacteria turning the nitrates *etc etc* to nitrogen exiting
the pond into the air? Should I keep the foam on there or sweep it
out?

Other than that, the only difference I see is that I dont have to
clean the filter everyday.


BUT: problem, why is it that 2 of my fish look like they have broken
backs?

Ammonia or nitite poisoining.

Can only repeat the suggestion: get them out of there (all fish) or watch
them die a slow death.

Not even 500 Biotec10's can help you with this I'm afraid.
