how to kill everything in the tank?

Recommended Posts

JiCi

Never heard of this technique before. Thanks for sharing.

 

For exemple you can find some information here : http://blogs.thatpetplace.com/thatfishblog/2011/07/20/dipping-plants-to-eliminate-snails/#.VQhefuGgaH8

 

It works for me when I see eggs on my plants.

 

Sorry I wrote Alun (it's the french translation) but it's Alum (aluminium sulfate).

so could i just go down to bunnings get some chlorine and put that in the water? or could i just fill it up with pool water :O?

Fishmosy was talking about bleach but pool chlorine does the same job. If you just add pool water you won't know how much chlorine you actually added - perhaps you're not worried. 

You can use Milton tablets too or any other convenient source of chlorine if this is the path you've chosen. 

 

JiCi, I knew you were talking about Alum. Thanks for adding that info, I had never imagined that use for it either.

Yep pool chlorine works just fine.

well, nothing survives in pools, no algae or snails, so i think that should be strong enough, just add a bucket of pool water everyday as a water change to keep the chlorine up i guess. even if its to much, its ok, only reason i didnt want to use bleach is, if i spill water on carpet, it goes bad lol, and i have a foam rock wall, i dont want the colors to fade on that

well, i decided to bin all the moss and plants, and start again....

 

the pool water is in the tank now, ill leave it in maybe a week, doing a full water change once every 2-3 days.

 

think 1 week is long enough to kill everything?

 

ill be after some new moss, didnt like peacock moss anyway, doesnt like grabbing hold of things, any recommendations? christmas moss?

Do you guys have access to assassin snails? They are good preventatives for snail population explosions.

I killed everything in my tanks one time with peroxide(wasn't planned) about 20ml per 100L of 6% solution should do it. :thumbsu:

These aren't available in Aus.

Every time this thread bounces to the top I remember the day I just gave a few unmeasured sprays of peroxide to the surface of a small 20l tank to remove the surface film.  A little spray here, a little spray there, here a squirt, there a squirt, just a little spray can't hurt....

 

And 30 mins later..... well... see the topic of this thread.

what about draining the water snd leaving tank outside in the sun? ive always done this in the past when ive bought secondhand tanks. does anyone know if that would work or will some types of pathogens survive?

I remember as a kid collecting the black snails with red flesh that are predatory, I think on other snails. I guess they qualify as "Assassin Snails" but they're certainly not aquatic. I've told someone before on this forum that we can't get them here but I wonder if there are any native, predatory aquatic snails that we can get. Someone will know, they're just probably not on SKF. 

 

UV sterilisation via the sun should work ok, remember that regular glass doesn't allow much UV through so it won't be as effective as you expect. Most sterilising agents will work on a bare glass tank. Chlorine, alcohol, peroxide are all good. Formalin works if you dare to use it. The important part is to be sensible about it. Metho leave a residue that must be rinsed out. Some things could damage the silicone. Gravel is hard to rinse so heat is probably a better option there. 

 

Mycobacterium is one example of a persisitent pathogen that probably won't be killed by a short exposure to the sun. I think bleach is required, Fishmosy will know.

UV will kill even the most stubborn of bacteria and their spores. It just depends on the dosage they get. If you are going to completely empty the tank, give it a slosh out with either a capful of bleach and water or salt crystals in minimal water, which have the benefit of a slight abrasive action. Then rinse well and leave to dry in full sun for a few days.

The combination of bleach or salt, lack of moisture and sunlight (heat and UV) will definitely get rid of any bad bacteria and their spores.

With regards to native Australian snails that prey on other snails, these are common in marine systems but I'm unaware of any existing in freshwater. I've sent emails to a couple of researchers currently working in this area. Will report back when I get some replies.

OK recieved a reply from Dr Frank Koehler from the Australian Museum.

Quote: "None of the native Australian freshwater snails is carnivorous in the sense that it preys on other fw snails."

Thanks for clarifying that for us. Now we know.

..so what about a freshwater leech that exclusively eats snails.  Helobdella papillornata.  See last paragraph: http://static-content.springer.com/lookinside/art%3A10.1023%2FA%3A1003543314841/001.png.

 

Gyraulus (mentioned in the paper) is a lot like the "mini ramshorn" that plagues many people.

 

Edit:  I suspect they will be a cold water species that may not tolerate the temps many of us have our tanks at.... but I really want to try to find them now.

The section of the paper you linked to mentions the leeches were kept at 16 - 24*C, the upper end being perfect shrimp temperatures. If you track some down, I'd be keen to give them a whirl.

Yep we should all be looking for these when we're out finding things. Great find Grubs, I didn't know something like this existed.

      It must have been an aluminium heatsink. The Indium in Liquid metal will eat through aluminium. Only copper or nickel plated heatsinks can be used with liquid metal. It says so on the packet, at least my pack of Thermal Grizzly Conductonaut does.

      I will try to add all the old tank's shrimps at the end of August to the new tank, had a problem with my chiller this morning, try to make it more efficient by adding a better heat sink grease, I added a liquid metal grease, apparently you can't add liquid metal, when heating up, the heat sink turning to dust, along with part of the cooler inlet and outlet. So far the shrimps are ok.

      I have had the new shrimps a week and have ordered some new ones(10) for delivery friday. There are probably at least 6 of the 8 alive (they may even all be alive still) but as the tank is so densely planted it is difficult to tell, but I saw 2 black and 2 red this morning, as yesterday, but I'm sure 1 red and  1 black weren't the same as the ones I saw yesterday so there are probably at least 6, if that makes any sense??? Anyway that will be it for now and I will just let the tank and shrimps do there thing once this batch are in there in a couple of days, and I can get back to the usual routine as was, before this unfortunate event wiped out the last lot. All parameters are good, including the nitrates now, but there are a lot of brown patches on the plants and moss balls still......... It all looks a bit drab and uninspiring and brown!!! I probably just need to be a bit more patient? I will do some maintenance tomorrow and a small 2L water change, then the new shrimps will go in on friday after acclimatising. The shrimps were totally uninterested in the spinach or shrimp lolly I put in at the weekend but I am assuming they have so much biofilm at this stage that that is keeping them busy and well fed and they are staying under cover until they get used to their new environment and this strange ugly monster that keeps peering in at them through the glass from time to time? I guess if some 100ft tall bloke kept peering through my window a few times a day I would be a bit nervous/reserved shall we say? I removed the spinach and the shrimp lolly and put the shrimp lolly in the betta tank and within minutes there were 10 shrimp on it so there was definitely nothing wrong with that shrimp lolly!

      Traps don't work on hydra. Even with planaria, it is slow and it doesn't catch them all.
