You don't need to dilute vinegar. Full strength vinegar should kill any nasties. Just rinse everything well and leave it to dry in the sun.
If you are reusing the gravel, boil it or pour boiling water on it.
If you were using planted substrate, replace it with new substrate.
I'm particularly worried about the amphipods which have become a bit of a plague and burrowed into the substrate. But i guess removing all the aquasoil should resolve the issues. Hence why i want to run a diluted bleach compound into the system to ensure everything is taken care of. Would I be able to do the same with vinegar; running a diluted solution of water and vinegar into the tank and this will eradicate the problems for a restart?
I actually didn't think of this; I will definitely give this a go; i rinse out one of the dual sponges in the CBS tank with the aquarium water and use it to seed the tank. Great idea! Thanks @jayc
I was going to try a reputable breeder in QLD; but agree with you.
Especially for someone very amateurish as me; i'd be easily fooled into buying the wrong type.
Thanks again for the advice!
Absolutely only use bleach as the last resort, with nothing in the tank. (6parts water to 1part bleach for future reference).
Even white vinegar is safer and probably just as effective for removal of planaria and worms. After you clear the old tank of gravel, give the glass a quick wipe with a vinegar soaked kitchen paper towel. Rinse and let dry in the sun.
Use vinegar if that wasn't clear.
Set up the new tank as desired.
If your other tanks are free of pests, you can use the filter media to seed this new tank. Wash the filter media in the water of the new tank. Yes, it will be dirty for a while, but you will have seeded it with millions of beneficial bacteria and probably cycle the new tank in a week.
PRL, real PRL, are pretty rare in Aus.
They will demand a high price for them, so check the legitimacy of the PRL. Find out the PRL history.
Nice looking CRS is not the same as PRL.
