Fish choice

Id suggest avoiding using RO, it really isn't necessary for a large majority of hobby fish including cories and neocaridina shrimp.
RO just makes life harder.

I'd only recommend it for specialist fish or specific breeding etc such as wild fish, caradina shrimp, discus etc... so many run of the mill fish are tank bred and adaptable to most waters.

You could look at apistogammas for a feature fish/pair. Again if tank need they will be happy and even breed in hard water but you will lose some shrimp as snacks so establish a population first...

What Iain said. I've lived in very hard water areas and it doesn't matter one iota. Using RO water just makes life unnecessarily complicated.
Regular maintenance, including water changes, is far more important, and the easier it is to do the more likely you are to carry it out, especially once the honeymoon period has worn off...

P.S. with regards fish choice I'd stick with one or two shoaling or free swimming species at the most, they are much happier kept in larger numbers than 3; you need at least 8-10, but the more the better.

Thanks for the replies. So red cherry shrimp, Pygmy corys, and fish like cpd's will be ok in my water??

Red Cherry shrimps like hard water.

See if you can find fish from somewhere like <"Strood Aquarists"> factsheets, they will have experience from members with hard water. If you don't mind a bigger Corydoras sp. (but still not out of scale in 80 litres), then Corydoras panda is good in hard water, and will spawn successfully.

Hi Darrel,

Thanks for your reply.

Do you think cherry shrimp would be ok in my water hardness though?

I will have a look at the panda cory.

With shrimp, what I'd do is buy from your local fish shop - they'll be using the same tap water you are so if the shrimp are happy and settled there then they'll be fine in your tank too.

I've looked at local shops and the shrimp are crap! Tiny little things for £4 each!

They sell babies because they cope better than the adults with changes in water conditions. They grow up though and you only need one of each to make a lot. Either way expensive is good news if you want to trade some back later :)

Thank you

Do you think the best method to acclimatise them is the drip method?

I introduced my first shrimp and fish to a tank recently. Using the rolled down bag and adding a bit of water method for the Amanos didn’t go so well, I added them a bit too quickly which may have been why I lost one. With the fish, Neons and Otos, I used the drip method into a bucket over a period of about an hour (some recommend two hours but I was using tap water of a similar chemistry to the local fish shop) no losses or immediate issues. Some trouble with getting the Otos to settle but this is unrelated to the method of introduction.
Hope this helps.
 
Thanks.

I'll have a look into this a bit further. Is it basically a length of tubing and a valve?

Yep, it's just a very small syphon with a valve to control speed. You can replace the valve with a peg/clip/knot but it's slightly harder to get the speed right.
 
cherry shrimp will be fine in hardwater, especially yours.

Regarding the RO water debate, I tend to half-agree, you can get away with using tapwater for a lot of fish, but if I have a fish that comes from parameters far outside my tapwater, that's when I'm more likely to utilise water buffers etc, as I feel they are healthier in water closer to their natural habitat.
