was hoping someone knows about water filtration.

my tap is 700+ ppm.

i was looking at some under the sink filters . one was 40 microns and one was 5 microns. it seems that the 40 micron is more for rust and sediment and might not help with the tds.

thanks

well im not getting much input so i might just use a filtret system from walmart because they are good about returns. so ill use it and measure the tds. if it doesnt bring it down to at least 300 then i will just return it. and start over.

I use a reverse osmosis system> Depending on how many gallons you need and how much you want to spend it is a great way to go. The main thing with r/o water is how much water do you need. The under the sink type will hold between 1 to 3 gallons at a time. When the water is gone it can take a few hours to refill, but your ppm will be somewhere between 2 and 7. The cost is between 150 to 300 and they sell them at home depot. There is also one sold by many hydroponic retailers for around 250 that hooks up to a male hose end and can deliver more water faster, but it still dribbles out so you really need to some up with some kind of storage system to accumulate water. The end result will be about 3 to 4 ppm.
You should not use softened water on plants. Sorry if you already know that but with 700 ppm sounds like you might be on a well.

That will work if you need 3-5 gallons a day. Maybe 10. But in reality it is for drinking water. Not to fill a reservoir.

What if i use the bypass on my softener and go with striaght well water its drinkable it just has a bit of iron in it?

still wont take you ppm down, just get a R/O unit, they are cheap and work forever as long as you stay on top of your filter changes. Most RO systems should bring your main TDS WAY down to manageable levels.

Honestly, no I don't. I have been looking at them though, but those set-ups don't fit into my plan. As to their quality, as far as I can tell the product looks decent. I would use them for making water for my plants. I don't think I would if had a reef tank at home.

Guys,

For the most part the internals are the same on these RO units. With the exception of the capacity. The diffrence between a 30 gpd and a 150 gpd is the membrane that cost about the same and a pressure limiter that cost like $2.00 . So long as you have enough pressure you don't need the booster pumps to do the 150 gpd system.



I picked this one up used on Craigs list for $75 and replaced all consumables in it to turn it into a 150 GPD. I added a cheap dual in-line TDS meter so I could tell when it was time to replace filters. I would bypass the DI portion of things. It is better to leave some mineral content. And you need to replace some of the calcium if you go this route to around 200 ppm before you start adding nutes.

A great place to get a good RO/DI system is
http://www.melevsreef.com/shop/index.html . He sells to the Aquarium Crowd.
A good place to buy consumables cheap is

And it looks like they have a 75 gpd unit for $159 right now.

Have a great day.
