Backyard Aquaponics
A place to discuss aquaponics

So there's no way known (yet) to kill off the parasite in the AP system, in the same timeframe as the fish have been removed to the hospital tank, i.e. a few days? Keeping a load of fish in a small intensive care unit can be just as stressful (or more stressful?) on the owner and the fish!

Just goes to show how careful one must be when dealing with closed loop systems, such as AP.

Thanks for the replies.


We were without power in Rockingham for 48hrs from lunch time on a Sunday to lunch time on a Tuesday in June. I bucketed water from my sump to my grow bed every hour, day and night to keep them alive............. and now their all dead!

Well I've taken out at least 20-30 dead/dying fish mostly smaller ones and filleted 10 of the bigger 500gm-1kg fish that were still relatively strong. I ate some last night and haven't broken out in any rashes and my gills appear fine!

The half a dozen little trout that went in a few months ago seem to be doing ok, though they still arn't really eating. I think maybe thats where it came from, I thought I'd put a few in over winter for something different but I wish I hadn't now!

I'm pretty devo'd over this, it's nearly enough to not do edible fish again as I catch enough Snapper, Mulloway ect to keep the freezer stocked. KOI maybe

Cheers again

sux that it happened... it's one of my concerns when I set up my system again.

Someone suggested that a few minutes in chlorinated tap water could kill the parasite... going by that logic if you kill the fish and then let it soak in chlorinated water for a bit before cleaning it it should do the same job.

Koi can get whitespot too !!
I think your experience shows yet another benefit of maintaining salt levels of 2 -3ppt in your system, as whitespot wont survive even at those low levels.

Yes salt and the benefit of keeping an eye on your fish! Been working days lately and not paying much attention to the fish, just chucking a few handfulls of feed in, in the afternoon and watching them thrash the surface. Wasn't till they stopped eating that I had a good look and by then they were covered.

I'm thinking of doing alittle restructuring of my MY SYSTEM as I have some more room to play with and would like to grow a Murray cod nice and big in the 1000lt tank by itself. Although the way I have the drain pipe in the FT to a sump does keep the FT nice and clean. Maybe I should just buy more tanks?

Live and learn!

Ick can be killed by a sudden change in salinity. You need to take you fish to a bath of 10kg salt per 1000 liters. If you want to use less water keep the same ratio. ph needs to be the same as your system and chlorine removed.
