Fmxmatt Posted November 3, 2007 Report Share Posted November 3, 2007 I think it depends where in CHC you are. I know when we were pumping our own water when we lived kind of rural (out airport way), we had to get another pump put in. At that time we got a TDS reading and from Dads memory it was 0 or very very low Theres always going to be arguements between people who use it and people who dont use it. I've also seen tanks run on tapwater which look outstanding, but the more I research, the more I see, that if you want absolute pristine conditions, then RO/DI is the easy option. I'm not saying it isn't possible with tap water, but there would be far more work involved. At the moment, i'm happy with the Tap Water until I can afford an RO unit Link to comment Share on other sites More sharing options...
reef Posted November 3, 2007 Report Share Posted November 3, 2007 there are many examples of great reef tanks here that dont use rodi conch is one of them show us the great reef tanks? Ro/di is not a must but everything you can do to reduce waste going in the tank the better. Link to comment Share on other sites More sharing options...
wilson Posted November 3, 2007 Report Share Posted November 3, 2007 well for starters there is conch's tank. last i herd laytons tank didnt use rodi either they are just a few from this site Link to comment Share on other sites More sharing options...
wasp Posted November 3, 2007 Report Share Posted November 3, 2007 Well I don't see it as an argument, more a group venture to gain knowledge, a positive thing. IE - can Chch tap water be used straight? It is possible to run a good tank even with Auckland tap water, depending on how much money you want to spend keeping the tank clean by other means. You could run mega phosphate resin for mega dollars, but an RODI will cost less in the long run. It's a trade off. At the moment the discussion is still a little vague but when Jolliolli has got the test results we will know with more certainty. I didn't want to start any aggro more just there are a lot of new people setting up in Chch & be good to have correct, fact based info for them. BTW Jolliolli, if it's hard to organise the tests, drop me a pm with your address & I'll send you down a TDS meter to borrow for a while. A few tests can be best, many factors come in even things like wether it just rained. So a few tests spread over some time, and some locations, will give most reliable info.

reef Posted November 3, 2007 Report Share Posted November 3, 2007 Testing the water is going to show high TDS as tested before in CHCH. Ro or di water has a tds of zero, no town water supply or even rain water is going to be zero as they all are going to contain some sort of trace elements and nutrients. One of the articles above states not to use pure water alone in the aquarium as it contains none of the minerals that fish require and has no ability to stabilise pH That would be for fresh water tanks not saltwater as the saltmix containes all the minerals and most salt mix is designed to use with RO or Di.

jolliolli Posted November 3, 2007 Report Share Posted November 3, 2007 This is a great discussion! I spoke to my friend last night, she didn't think they had a TDS meter in her department but will check for me on Monday so i'll find out then. If not then i'll get touch with you wasp and let the testing begin! Link to comment Share on other sites More sharing options...
tHEcONCH Posted November 4, 2007 Author Report Share Posted November 4, 2007 Eerrr..... looks like I've joined this discussion a bit late! As you guys probably know I don't use RO/DI water in my RSM, but I feed heavily so as a percentage of total nutrient/waste input the content of my tap water is probably insignificant - that said, if I were going to concentrate on SPS I'd probably invest in RO/DI. I'm keen to see the test results! Link to comment Share on other sites More sharing options...

tHEcONCH Posted November 28, 2007 Author Report Share Posted November 28, 2007 Its actually lost a lot of its colour - it was / could again be, a quite beautiful bottle green - but it needs to be in a much bigger tank to look right. Link to comment Share on other sites More sharing options...
Zev Posted November 28, 2007 Report Share Posted November 28, 2007 Awww they're cute... Are the Ultra blues? Just be careful if you are going to leave them on the substrate, the nasty bristle worms will be very interested in invading them through the byssal organ if the don't attach.
