Is RO water needed.

Hi. I currently have a 240 litre tank containing all male malawi cichlids. I ve always wanted to keep marine fish, so I ve decided that after I get married in June I'm going to make the plunge. In order to gain as much knowledge as possible between then and now I ve been reading as much on the subject as possible. One question I have is will I need to run the tank on RO water. It will be a struggle to find the place to install a unit and don't really want the extra cost of always buying 50+ litres every couple of weeks. Or can I not get away with ordinary treated tap water???

Personally I don't think it's worth the effort and maintenance to deal with non RO water.
It's just going to make it so much harder to have a great tank.

Couldn't agree more. If you can't get RO water I'd stick to cichlids. Using RO is that important. It's just one of the many expenses of going salt.

I agree with what the others have said but if your only worry is about were to install one that is an easy fix.

Fact is you don't have to install it anywhere simply hook it up to the sink when you need to fill some buckets of water and store it in a closet when not in use, you can also instal them under a sink or near a washer hookup. Its really that simple.

^This, plus the models that hook up to a sink can often be found for really cheap!

Mine is under my kitchen sink. You can also use it for your own personal drinking / cooking water. Believe.me you won't go back to tap water again.

It is best to have a RO/DI unit. RO alone is not good enough. It will take out some of the junk in tap water but not all. You can buy a faucet adapter to hook up to sink

Ok. So I could just turn on the tap and hey presto RO water. Water so you recommend if RO water is not enough alone.

RO Membrane alone will remove some stuff but not all the DI Resin will pollish it off. I have a TDS meter before and after my RO membrane TDS reads 86 going in and 77 coming out. Once it goes through the DI it reads 0. The unit I recommend is below.
