Water for Water Changes

[megatron_55]

Hey just thought I'd put my two cents . . . Most people use RO (reverse osmosis water). In order for you to get RO water is to buy a $300-$400 machine that will convert your tap water to a reef friendly water. But like I said the water that I get from Superstore or Save on is filtered and also says purified using reverse osmosis technology . . . But I mean tap water ain't bad . . . But I'd rather not take any chance =) . . . Tap water has chlorine and some metals in the water. Chlorine kills fish and metal substance will destroy your inverts (corals and invertibrates)

FYI, a nice RO/Di unit can be bought for around 100 bucks over at ebay here. Not as fancy looking as some of those other units, but I hear they're have the best bang for your buck. You can also contact them directly at 604-922-3030. I believe they're located in the Vancouver area.

I started with bottled water from Cosco. But I have now gone to RO water filter. I picked mine up off of Ebay for about $120.00 CDN

I've just started using one of the Aquarium Pharmaceuticals "Tap Water Purifiers".. It's strictly a DI unit but works well. The only obvious downfall to DI only is resin fatigue.. Some people in the UK reported they got 17 gallons (!!) of water before it was worn out. When our tap water in the Vancouver area reads around 10 ppm TDS, the cartridge goes a lot farther.

If you've got 10 ppm tap water readings, there's absalutely no need to do anything to it. Just add salt!

wrong, way out to lunch on this one. we may only have 10 to 20 PPM in our water depending on the time of year but remember that is only metals.

Don't forget about phosphates, algae content (which we have a very high level of due to the mild weather) silicates, ect that are not part of a hardness test.

Victoria/Vancouver water is very soft , has a low PH, but has lots of other junk in it.

"Dissolved solids" refer to any minerals, salts, metals, cations or anions dissolved in water. This includes anything present in water other than the pure water (H20) molecule and suspended solids. Suspended solids are any particles/substances that are neither dissolved nor settled in the water.

we may only have 10 to 20 PPM in our water depending on the time of year but remember that is only metals.

Only metals how?

Other disolved solids include Sodium, potassium, Bicarbonates, carbonates, Sulfates, Chloride, Nitrate, Floride, Boron and Silica. All of which are not metals.

Good ol tap water here

Tap water with "Prime".

I use to use RO water on my old er tanks and then switched to RO/DI after after got a awesome deal on a 100 GPD RO/di unit 5 stage. Like RO/DI better .
