Help please

[BarryW]

Hi,

I have just joined this forum to help my father in law who recently lost all his marine fish unexpectedly. He sent off his water to be tested and received the results. Please could someone shed some light in these results and if any of these are the cause for his loss of fish?

many thanks indeed.

Nothing in those results would have killed off all your fish IMO. Disease or something else (Ammonia, lack of O2, heater malfunction, etc.)
