    My first post...

    I have a Rio 180 that's been in service about 6-8 weeks. I use the internal filter and an Eheim 2213. I have the normal 2 T8s of unknown age (second hand tank) and 1 new T8 (so 90W in total).

    Currently, I change about 10% a week with water that I have taken directly from the mains (i.e. unsoftened) but heated to the right temperature with a spare tank heater first. I'd like to use EI method, but on my Rio180 that means swapping 90 litres a week. I presume when most people do this, they use a python arrangement and get the water to right temperature by mixing hot and cold water. I have a Kinetic water softener (the one that runs on water pressure rather than electricity)... so that means I would be adding artificially softened water if I added hot water. I presume if I just added cold water, my fish would freeze!

    Am I OK to use the softened water?

    Water softeners that use salt or brine (NaCl) are not a good idea, primarily because the sodium content can become problematic. Freshwater plants have difficulty dealing with high sodium content. Freshwater fish will have a problem as well. It depends therefore on how much of the softened hot water you use to bring the temperature of the cold un-softened water up to temperature. Try something like a 10:1 ratio (cold to hot) and see how that goes. If there is any way to substitute KCl for NaCl in the softener that would help.

    Welcome to the forum Peter.
    Personally I can not see a problem - I will retract my statement - I have just done a google search on the sytem use are using - http://www.waterways.ltd.uk/index.php?m ... a314914495 but I am sure some of the guy's especially ed, steveuk, Ceg and arron with advise you better, one thing you need to do - every body will confirm this 50% water change is recommended if you intend to use E.I. I have one hose pipe which empties and fills: one end has a strainer http://cgi.ebay.co.uk/Eheim-16-22mm-Inl ... 240%3A1318 so the fish don’t go up the pipe and the other end has a no return valve http://cgi.ebay.co.uk/Hozelock-2185-Wat ... 240%3A1318 and a mixer tap connection http://cgi.ebay.co.uk/Hozelock-2274-Mul ... 240%3A1318. I initially draw of 50% of water (gravity feed) and it goes down the plug hole, as for filling I mix my water (hot & cold) to the desired temp prior to filling (aim for 70 degree C) pinch the pipe and then release the pipe once in the tank and fill to the desired level - whilst its filling i add my dechlorinator. Easy peeze all done in about 20 mins.
