A basic nano tank can be run on just a heater, lights and powerhead. The best thing you can do for a marine nano is regular water changes. I did run one of them without a protein skimmer, but that was with only 1 small fish in it. A lot of people keep nano tanks with just corals in them, with maybe a couple of small fish like clownfish or gobies. The main thing you need is patience, only bad things happen quickly in marine tanks
Thanks for that....
I think Im still a wee bit away from the marines..I do recal a trip into town to a LFS and was interested in trying to make my Juwel 180 into a marine tank and I thought I was going to have to sell a kidney to get all the gear I needed..
Im sure you will sell them in here at the price your asking
I used to think the same as you, but marines are easier to keep than you think, just don't believe anything the shops up here tell you and you will be fine.
I started with a rio 240, and got all the kit from a mate who was selling up and bits from ebay. It cost me less than £350 to get it going, but I spent more once I knew what I wanted to keep in there coral wise. I have a 2 foot cube for sale atm, with a sump, return pump, all the pipe work you need for £150, all you would need to add is a light and skimmer and you would be sorted. If you look at the specialist marine forums you can pick up gear cheaply enough. So it may cost a little more than tropicals, but not that much more and once you change you won't go back. I gave up 25 tanks full of malawis for 1 marine tank, and I don't regret it at all.
