[crage34]

most of us actually started on tap water, it's just undesirable as most tap is loaded with nutrients like for example mine contains 6-9ppm nitrate, plus measurable amounts of other solids like phosphates etc., will lead to excess algae blooms. if you are not going to do a reef (where nitrates are critical), you can get away with tap or maybe faucet filtered water, like pur or callogen.

I got mine at Wal-mart for $0.58 per gallon. Just read the label and make sure it says it was purified using reverse osmosis. Mine is a 75 gal so it cost me about $50.00. Having a 30 gal, it'll be less than $20. I don't know how much of a difference it will actually make but compared to all the other associated costs, the water is relatively cheap.

You can get an ro/di filter unit on ebay for $135.00 shipped. If you use tap water and yours is anything like mine, you will be fighting cyano constantly.

r/o water at my local grocery store is only 13cents a gallon. sounds like WalMart is ripping you off...since my LFS only charges 20 cents per gallon.

I bought distilled water from Walmart for that price. I didnt notice any labels on the bottled water saying purified using RO. What was displayed on the label of the bottled water? I recall seeing distilled, drinking and spring...

did u have to buy one of those 5 gal water jugs for drinking water like in doctors offices, to fill up at walmart(thats gonna take 6 trips for my 30 gallon)....also is it ok for me to mix the salt into the water in the tank? ( for the first fill up) also should i add the sand before or after fill up?(for the first fill up)

sorry for all the stupid questions but i was wondering when the water evaporates out of your tank and u top it back off, since the salt doesnt evaporate with the water do u top the tank back off with the regular salt mixture or do u top off with a mixture with less salt in it?

I can get it cheaper if I want to supply my own containers, but that's not worth the hassel. I assume for 13 cents, this is what you are having to do.

First of all, don't consider any question that you don't have the answer for "a stupid question". That especially applies with fish and sw tanks in particular.

Definitely top off evaporated water with fresh water. Use the sw for water changes and the initial fill-up.

One of my local grocery stores has a water unit outside that sells ro water for 25 cents per gallon.

See if your lfs will lend you the 5 gallon jugs that you need for initial fill-up.
Invest in a 5 gallon jug or two to have for transports after that for water changes.

You can mix your initial water in the tank. In regards to the timing of adding the sand, I would suggest mixing the water first and then adding the sand slowly after all the water has been mixed.
