chris b Posted July 6, 2014 Report Share Posted July 6, 2014 Hello all I am working on building a sump for my 1200L, I have a 200L tank running 2 filter socks and am going to try k1 moving media if I can find some. I am going to run an auto water change drip system with overflow to drain which I was wanting to use this http://www.trademe.co.nz/pets-animals/f ... 340152.htm to clean the water coming in. Has anyone used them? do I need to add anything to the water to keep fish Health? I have read using ro can make ph unstable is this correct? Thanks chris Quote Link to comment Share on other sites More sharing options...

Has anyone used them? Except for some extreme circumstances there is absolutely no need for an RO filter for water change water with freshwater thanks. do I need to add anything to the water to keep fish Health? Only thing you probably need to add is something to neutralize chlorine, otherwise straight from the tap will be good. I have read using ro can make ph unstable is this correct? Extremely unstable, wastes huge amounts of water that would be better off used for water changes, wastes money. You'd be using stripping all the hardness and minerals out of water that may not be perfect but is probably very usable and then spending money to put them back in so your fish can survive in it. The ONLY time an RO filter would be used regularly for a fishtank is for a marine tank and the majority of that is for topoff water. Quote Link to comment Share on other sites More sharing options...

Silverdollarboy2 Posted July 6, 2014 Report Share Posted July 6, 2014 Use seachem prime for a de chlorinator Quote Link to comment Share on other sites More sharing options...
chris b Posted July 6, 2014 Author Report Share Posted July 6, 2014 Use seachem prime for a de chlorinator I don't want to have 2 add anything I was hoping for a filter cartridge that i can change say once every 6 month sort of thing Quote Link to comment Share on other sites More sharing options...
Ira Posted July 6, 2014 Report Share Posted July 6, 2014 I don't want to have 2 add anything I was hoping for a filter cartridge that i can change say once every 6 month sort of thing You could use a carbon cartridge to remove the chlorine. Tends to be more expensive than something like Prime. But if you're running a constant flow water change system even that probably isn't needed.

David R Posted July 6, 2014 Report Share Posted July 6, 2014 The ONLY time an RO filter would be used regularly for a fishtank is for a marine tank and the majority of that is for topoff water. The only other time it could be necessary is if you have exceptionally hard tap water and are keeping soft-water species that are delicate enough to suffer with incorrect water (discus, uaru, angels etc). And in that case, in New Zealand at least, it is far cheaper and easier to collect rain water to help soften the water. How are you going to do your auto system? Pump to waste on a timer and a float valve to control the top off, or drain in the sump and incoming water dripped/pumped into the tank?

Thanks heaps If you use a standard drinking water filter (like BRITA), these typically eliminate 99% of chlorine but remove SOME minerals and hardness.
