Ok so the tank is plumbed, all ready for my to go and get the sand, water and live rock on the weekend! :D

I'm a little confused on the water aspect. Should I be buying RO water and salt and mix them together, or should I be buying natural salt water?

Also, what kind of sand should I go for? 2mm coral sand?

The sand is up to you. Depends onw hat look and texture you want. I went cheap and used 250lbs of pool filter sand for my 125 and am very pleased with it. Has a nice size grain but not too big so sifters can still sift without hurting themselves. The color choice is limited though, it;s just plain colored sand.

You can buy ro/di water and salt yourself (my choice if I were you) or you can buy the premixed salt from them.

In the future you can look into buying an ro/dio machine of your own so you can mix your own water and it will end up costing pennies a gallons in the end. and no lugging bugs and jugs to the lgs. LOL

Thanks for the tips Carey. So what is the main advantage of buying the RO water and adding the salt myself over natural salt water?

I can't really buy an RO/DI machine, just no room haha!

I have a portable one that fits in a shopping bag that I only take out once a week to make water with. No hard plumbing required either, will hook up to a garden hose or a sink faucet.

here is the link for reference

I find its very convenient to make my own saltwater and I know exactly what I'm putting in.

Also if you buy premixed SW you need to also buy pure ro/di water for your top offs due to evaporation since that will raise your salintity levels. So topping off with ro/di is important.

When I was buying my ro/di from alocal lfs it contained ALL the things it wasnt supposed to, so you alwasy take that chance to if youre not doing it yourself.

Heres the link for the ro/di machine. small enoguuh to fit in a small shopping bag whennot in use.

There always room for a ro/di I have mine order a small vanity cabinet in my bathroom running off my bathroom sink in my aoartment . Carey has the link for the best priced and most compact unit on the web that I found. making and mixing my own water has been one of the best things for my tank, my back and the breaks in my truck driving every week to go get water pre-made. No to mention to fill your tank u will need to buy 11 5 gallon buckets to do your first fill.

The 60 bucks I spent on my ro/di was the best investment I got for my tank

$50 postage to Australia :( So how do these units work exactly? Like I said I have no room at all around my tank, and it's in my bedroom so I can't use it in the same room as my tank if that matters?

You need a kitchen faucet or an outdoor garden hose and someplace that the waste water can run off to. I use mine on my back porch, the waste water waters my grass and plants and the pure water goes into a 32g garbage can.

paulweck 09-07-2011 09:43 AM

Mine sit under my bathroom sink when and hooked up my a sink adaptor that they give u. When I need it I take the waste hose and put it in my sink drain. And when I fill water I put the bucket in the bathtub so if it overflows I have nothing to worry about. And for filling my tank I just went out and bought 25 feet 1/4 inch tubing and connected the rodi so it will reach my tank I sat on the couch and watched my tank fill up

carey 09-07-2011 09:54 AM

I have a small pump and like 18feet of hosing so if I wanna do a water change form the garbage can of water I can just drop it in and refill. I use a python to drain the water and the rio pump to fill her back up. Though I have to admit, last few water changes i actually used buckets, so much eaiser to know exactly how much went out so I know how much to add back. But I like having options. :-)

matthewh133 09-07-2011 10:02 AM

I feel really stupid, a lot of that confused the crap out of me lol. Sorry! So basically the machine sits in something like a drum full of water. It weaves its magic, the water in the drum turns into RO/DI water and also filters out the waste water into somewhere else? Then I can just fill up buckets and take them upstairs when needed?
