    How bad is it really, and is an RO machine essential ?

    Will cause algae growth.

    That said when I started my tank I used the tap water to cycle the tank as I did not want to waste 1500l of water that I tested my newly built tank. As algae growth is part of the cycling process, this was not a problem.

    It depends on the water that comes out of your tap....

    Some municipalities have VERY toxic water (Slummies for the most part) and compensate by dosing it with chlorine (which will cleanse your tank of all life) and other municipalities have water that is OK. I'm out on the beach outside of PE and our water gets re-chlorinated just down the line from me, so my water is generally chlorine-free and usable. Although relying on tap water is a BAD idea as every now and then they OD the supply with chlorine and this will mess your tank up in a big way if you top-up on those days. To bypass this problem, I fill up reservoirs which stand in the sun outside for a few days before I do a top up with tap water. This allows the chlorine to evaporate out.

    How much phosphate is in our drinking water then ( Durban ) ?
    Has anybody got access to a chemical analysis of the water we drink everyday ?

    RO water seems like such a hassel, and the amount of waste water seems irresponsible. Yes is can be used in your garden or pool etc, but then you need keep a container for it and ... hassel factor.

    Wont running a decent phosphate remover in your tank just eliminate this problem ?

    That sounds interesting Richard, so would boiled tap water (cooled down) be better to use?

    Phosphates are not the only issue with tap water. Its all the dissolved solids and other nasty chemicals that are the problem.

    Chlorine

    Chlorine is used as a disinfectant to remove potentially dangerous bacteria and other micro-organisms.
    Chlorine is one of the major causes of objectionable taste, smell and odour in our drinking water.
    Chlorine has been identified as a potential carcinogen.
    Fluoride

    Fluoride is added to protect against dental decay particularly in young children.
    Aluminium

    Aluminium is added to our water supply to act as a flocculant, ironically to make the water look clearer
    From Pipes

    Water travels from the water treatment plants to your house through a network of pipes, including those in your own home, and some of these pipes may be well over 70 years old. These pipes can contain a range of contaminants which may enter our water supply. Among these are:
    Dirt, Rust, Slime, Sand and Mud

    These contaminants build up over a number of years and can cause the water to be dirty or worse. They can be particularly prevalent when pipes are accidentally broken or accessed for repairs and maintenance.
    Copper and Lead

    Copper and Lead can leach into the water supply from the copper pipes in your house and they have been identified as particularly dangerous to health.
    Chlorine Resistant Parasites

    There are a number of hard shelled protozoa which are resistant to chlorine disinfection. Cryptosporidium and Giardia have been discovered in domestic water supplies in Australia and they can cause immediate health problems if ingested.

    I don't think anyone would recommend that.

    Ok, but what are those nasties ?
    Apparently we have some of the best drinking water in the world, and one of a few countries that can still drink water out of our taps - so how bad is it ?
    Im still here, and I drink the water everyday .. :thumbup:

    water quality will change everyday. Getting RO filter is the cheapest soloution for total peace of mind.

    I dont know if I agree with that.
    Sure, maybe miniscule changes are possible, but for the most part it stays the same.
    You will know, that morning when you open the tap to brush your teeth that something has gone horribly wrong with the water. Where I stay the water tastes the same everyday.

    you will be supprised at what goes down at your local water purification plant!
    What tastes good to you might still be bad for your tank.
    Do you really want to gamble with your livestock?
    Its not like a RO filter is all that expensive, and buying RO water from a vendor is not expensive either.

    Our taste buds are not sensitive enough to pick up changes in quality.
    Water quality does change regularly. Theres no set water standard, rather an allowed range for drinking water.

    I would still say these are not recommended for use in a marine tank.

    Do yourself a favour and watch this video.

    If you don't like the answer you get does not mean it's the wrong answer!!!

    out of all the people that keep marine tanks most as in 90% of us have an RO unit and there is a good reason - the cleaner your water is the better if that logic does not make sense well then we wasting good energy here.

    Chlorine is not as bad as chloramine which is used in tap water. It doesn't dissipate easily
