    Hi everyone, just a bit of advice needed.

    I always get my salt water from my LFS for £1 a gallon and just wondered how feasible it would be to get an RO unit and make up my own. Before I started the hobby I looked into getting one but would have to pay around £40 for a 2nd hand unit, then £50 or whatever it is for the bucket of salt.

    I will be needing 18 litres of salt water per week (if I'm doing 10%water changes but thinking of upping it to 20litres)

    by the time I have finished buying everything I need I'm just unsure whether or not it is worth it. Like how long does a bucket of salt last?

    Cheers everyone.

    Think you get about 700 litres out of a bucket of salt

    Do you have somewhere to put an RO unit that's practical ?

    And salt lasts as long as it doesn't get wet that would probably keep you going for nearly 2 years...Karl...

    only on the decking really outside, and even then I don't really want buckets/tubs all over, really undecided whether to just carry on as I am now or do it all myself.

    I've just bought an RO unit from Little Ocean but haven't set it up yet (lazy......). I haven't got a permanent site for it so it has ball valves to keep the membrane wet when not in use. Just an idea if you're struggling for room.

    my laziness is the only reason I have not gone for one yet, just easier letting people do it for you. I always do tests on it before it goes in and then test the tank the day after. So I know I am not just putting rubbish in. Will see anyway but think I am gonna carry on as I am right now and get an RO unit if I see a bargain come up.

    I've got one ordered for my water, i've only got a 130l tank, i have a 60mile round trip to the nearest supply though so its a no brainer for me as i'd be paying £20 in diesel to get there and back every week.

    If my lfs was close i would have probably used them as long as it was quality water.

    You wont know the TDS of the water once its mixed with salt, and knowing RO water from lfs it more than likely not 0. so contamins can still be put in tank throu polluted RO. This is the main reason why folk make there own RO, so they know exactly what there putting in tank.
    I make some for a neighbour which he pays me for which goes into a pot.
    if you can do same for someone it will pay for itself over time.:smile:

    Cheers for the advice Barracuda, do you think it may be worth testing the RO water I buy from them as well then to see what it's like? I know what you're saying about selling to a neighbour but don't know anybody local that deals with marines, apart from all the folk on this site. hmmmmm decisions decisions lol :D

    id go for your own ro, as you never know what yer getting from the lfs, im the same as jaytee if you have a garden tap like me its great. get a tap connector (only cheap) just have ballvalves on the pipes of the r.o. run what you need, close ball valves and store r.o unit away inside untill needed again.
