Filter bacteria dead during treatment?

**shaman** · 11th Nov 2005, 17:21

I have off my canister filter for treating whitespot. Does the bacteria in the canister filter die without freshair supply? Thanks!

**Justikanz** · 11th Nov 2005, 17:32

Yes... The bacterial will die off in about several hrs or so without oxygen from the fresh water passing through the media. Since you had disconnected the media during the treatment, that would mean at least 2 weeks. Please do not connect back your canister without washing the media thoroughly.

i have a question regarding removing media from filters during medication...
wun the white spot spores stay alive in the filters if we remove them?
and after we have treated the tank and connect back the filter, wun the spores go back to hunt down our fauna?

hi shaman,
normally when i do treatment your way i keep canister running with a bucket of declorinated water on a chair to keep bacteria alive. the white spot protozon parasite in canister will not survive without a host.

Since the ich spores would have gone into the filter. Personally, I would have treat the filter together with the tank to wipe the ich out, then I worry about cycling the tank again after that. High plant density would make the cycling easier.

Yes, with no hosts, the ich protozoan in the filter, if any, will die. That is provided the filter had been isolated for at least twice the life cycle of the ich protozoan...

Keeping the tank sterile is plan impossible. The ich protozoan/tomites or whichever you call it is there whether you like it or not. As long as the critters are healthy, they will not get sick. They got the ich for some reason namely stress, poor tank conditions.

arent ich also caused by the temp? Like lower temp?

**Justikanz** · 12th Nov 2005, 01:20

A sudden/big drop in temperature or fish constantly being held in water of too low a temperature will cause stress to the fish lor... Then the fish can easily be attacked by the ich protozoan...

Hi Shaman,
Read it somewhere, the bacteria in your filter will last about 2 hours after you shut off, after that---ground zero.

. Personally I don't separate the filter during treatment. I shut off periodically during treatment cycle, don't ask me if it works or not because I didn't check also

but no major problems.

after that.

Hi thanks for the replies. If the bacteria is going to die anywhere, so I might as well keep the filter running? At least the CO2 can be more evenly distributed in tank.

hi shaman,

may i know what is your weapon of choice?[against ich]

quite difficult to treat ich with plants in tank esp since the most effective one MB konks the plants as well...

**PeterGwee** · 12th Nov 2005, 21:10

Use salt....cheap and good. Ich isn't that difficult to treat.

hmm
if you salt the tank correctly, you stop the free swimming larvae and the life cycle of ich grinds to a halt
you should not see any recurrence of ich as long as you have treated for a sufficiently long period of time (cannot remember how long)

**StanChung** · 12th Nov 2005, 21:38

hi peter,

how much ppt salt do you recommend? i've made kiam chai[salted vegetables] before so i'm pretty wary.

**PeterGwee** · 12th Nov 2005, 23:17

1 tablespoon per 5 gallon of tank water. Top up the amount for the amount of water changed after that. Your plants won't be kiam chai one lah...as long as you take care of things. The critters were stressed for some reason..you need to take care of that. Focusing on the base of the system (plants) will solve all your issues really. That is why people say healthy plants equals to healthy fish.

hi peter,
can't agree more. only got white spot recently because parents overfed and neglected to siphon the excess food which were tufts like sago. your truly wasn't around. can't blame parents as they are 70. poor eyesight...

24/27 simulans

because of late treatment. sad. however not all fish were infected. the two biggest discus were fine.

your recipe for white spot salt treatment: 1 tablespoon-5gallons
ok that's 15g per 20liters roughly.

do you raise the temp to 30c as well?
