As jayc has mention, do check if you are allowed to import them into your country, I think Australia is ok as long as you applied for the paper work to import them, but do check first.
But this option are for those who are after good quality shrimp with a guaranteed of pure bloodline.
You can contact them through this email, they accept Paypal with a addition 7.5% on top, their Paypal account email is different, but email them first for relevant detail as they may differ from mine.

For me they cost with shipping and Paypal fee, its still cheaper them in Hong Kong.
I will have to delay this purchase, ADA and the CALs Black Earth Premium substrate are limited now, most places does not have stock, and no delivery date.
See, and I thought you meant weak solutions were just as susceptible. So I should pre-mix my 7 gallon tank when I get the RO water and it will last the 4 weeks or so that I use it to change water just fine. That's what I was after. Apparently the Salty Bee guys think the same. Makes sense.
Ok then. Will add more plants to try and reduce nitrates.
Thanks Simon and JayC for the pointers and hints. I think the Dino Spit is the Glutaraldehyde and the Dino Pee has the macro and micronutrients. I will leave off the Glutaraldehyde and reduce the dose of the Pee to one third. I am pretty careful with the dosing.
Good news is that there are at least two RCS females still in the tank and looking well. Maybe they went and hid and moulded after the big water change? The surviving DAE are all looking well.
Anyway will take all your advice on board and do smaller water changes and work out a dripper system.
