Glad we can be of some help and I agree you are doing the best thing by thinking it out thoroughly before you get started. It is very frustrating when you spend a lot of money on a small setup to then have to go and do the same again for another setup because it isn't big enough, way more economical and cost effective to get it right first time, though as you say you are starting with some of the stuff! I'm also sure that when I closed down the small one and moved the shrimps to the new tank that I probably lost half of the shrimplets as they were too small/young to be moved in reality but I really didn't want to have to run 2 tanks for a few months whilst I waited for them to grow - I had way too many anyway.
I can't be much help regarding the 'chiller' as we don't have hot enough weather here, in fact even the humans don't get that over here (except in expensive cars)? A lot may depend where you are placing the setup as well, mine is in a dark corner that doesn't get any direct sun. If it isn't likely to get too hot there for a while you can of course come back to that as a separate issue as it won't mean disrupting anything in the tank anyway should you decide to get one later!
You are probably best steering away from the CO2 as it is one less thing to set up and, as you, I have read a lot of reports saying it isn't good with caridina shrimp setups, though I have no actual experience with it, but why risk it.
Hope you will keep us informed/updated.
I agree with you both and you have changed my mind. I will go for mix of cardinia shrimp. Definately will be lot more interesting in terms of colours and patterns.
I do already have most of the stuff. The only thing that I do not is the Chiller and even though I do have the KegKing Co2 setup, I will stay away from it because its a cardinia setup. Will research a bit further into the chiller this, as I do not want to buy one for a small tank and realise that I need to invest on a bigger one down the line.
Thank you guys for the input. Really appreciate the insight.
P.S: Great pics Simon. That has certainly swayed me towards a mixed setup.
I started out with a 30cm tank, and it's my only shrimp tank, started of about November with Neo's and added a few Taiwan bee's, king kong, wine reds, pinto's and blue Bolts around feburary, my Neo's have multiplied, but given many away, and finally giving most away, leaving only cardinia, my water seems ok, since many of my cardinia are still here, and my Taiwan bee have berries, shrimplets should come any time.
I think you should be prepared to spend money, for me I have a HOF, CO2, water cooler and the right light, i'm intend to change the current substrate from ADA to the PB, but have to wait for the Taiwan bee to have shrimplets.
Having multiple tanks and a tank rack may be where you want to go eventually but that is probably for the future?
If you want to test out the cardina you may want to go the route I did in that having a mix of shrimps colour and pattern in one tank is certainly more interesting to look at than 10 tanks with single/pattern, and I keep getting new ones that I didn't have before, even the boss should like them!!!!! It is obviously a lot cheaper and takes up a lot less time and space as well. I got the 35L dennerle scapers tank (used 3L of substrate) and it is 40cm x 32cm x 28cm and it has 28L of water (my measuring jug is a cheap one so maybe inaccurate, but the tank isn't filled to the brim and stuff in the tank takes up some space). It would give you an extra 10cm x 32cm (plus 2cm x 30cm) which to shrimps is quite a lot, not that I am saying you should necessarily get this tank but just as an example of how less height (which isn't needed for shrimps) in a tank can make a lot of difference to the floor area of a 'similar' capacity tank, but you may think it is too much money for such a small increase, but obviously there is a whole range of other tank choices out there.I assume you would use the heater/light/filter etc from the old tank if you weren't going too much larger? And, of coarse, you can just stick with the tank you have and that should still work out fine for a starter/tester tank?
If you want to see the mix then just click on gallery/New images and scroll down. You should show the boss and I a sure it will swing it in your favour!
I don't think you should have any problems with caridina if you are sticking with remineralised RO water and proper shrimp products from the very start. It took me years to get to where I am now but I think ALL the problems I had were because I was trying to use 'tapwater', as soon as I started with RO remineralised no problems whatsoever.
Any other specifics/question feel free to ask away.
Thank you very much Simon.
I have certainly thought about the idea of secondary tanks. But i wanted to test out the Cardinia waters first. If they do capture my interest, I plan to seek my boss (aka wife) to approve the shrimp tank rack idea *fingers crossed*
I have been going through this forum and the Shrimpspot forum to gain as much knowledge as I can to get a good start.
Thank you again for your message. Every little bit helps.
