Whats coming out of the growbeds should have less ammonia.
How old is your test kit?

Have to agree with privatteer on this dubsy. At the worst, ammonia should be no different than the levels in the fish tank outflow. You probably had a spike of ammonia or nitrites which was enough to kill the fish, they just took a while to die.

the test kit is only 5 weeks old

amonia level has always been a 0 reading and nitrate levels are slowly rising since adding the filter before water reenters FT

i have tried to upload some photos but even tyring to upload 1 photo will not work as a error message comes up with file exceeds 2 Mib, ??

Hi dubsy, what is your houses roof, guttering and tanks made from? If its metal for any of the three that could be your source of contamination

Hi julia,

we have a tiled roof, colourbond gutters, water from roof intially goes into a 5000ltr poly water tank this tank is used for storage, then i have another 1500ltr water tank which gets used everyday & the water from the holding tank gets pumped into the usage tank through irrigation pipe, i think scotty & privateer are on the right track with the fish getting a lethal spike of amonia or nitrate,

dubsy

He means a spike of Nitrite (not Nitrate).
