Reverse Osmosis

[Anonymous]

Hello Everyone,

Thank you for inviting us to your board! :lol:

We deal in water treatment, the water to your tank (not in it),

Anything I (we) can do to help :idea: let us know!

Looking forward to any questions on reverse osmosis and DI you may have.

[Dustin]

can you explain RO and how much a unit cost?

[AquaFX]

Dustin,

RO is a process the forces water though a semi-permeable membrane. This splits the stream into a "concentrate" and a "permeate" stream. The concentrate stream carries the dissolved solids to the drain. A descend unit should reduce TDS (total dissolved Solids) by 98%. This varies a little depending on the contaminant.

Now, I can go on and on. You probably won't want to read all that I could say. But if you want to ask me specific questions fire away!!

The cost varies depending on your needs. The bigger the unit the higher the price tag. A small unit 50 gallons per day is $159.00 that is full retail

http://www.aquaee.com/aboutro.htm This is a URL to another site we have that is not really up at this time, but it has some very good information

Please, let me know if I helped.

[Dustin]

i think i might be able to borrow a freinds unit.

[AquaFX]

You will see a big difference. Your fish will love you for it! Also you can use it for your drinking water, try making coffee/tea with RO water :wink:

Members of this board get a 20% discount.

Let me know what you think after you borrow the unit. One word of caution, if you just get jugs of RO water from your friend, make sure they are food grade plastic (or glass) RO water is so pure, it will leach out impurities from some plastics

Marianne,

I am looking at a 7 stage from Aquatic Reef Systems. 200 GPD

I see you have a 5 stage and a 9 stage. Any chances on getting a 7 stage 200gpd. I think the 9 Stage is a little to much for me.

Thanks
Scott Gibbons

[AquaFX]

All our systems are made to order. We can build that system for you. It is the same as the 9 stage minus a membrane and a booster pump.

No Problem, I will do even better, I will pay you shipping!!! :shock:

Thanks for asking, I am glad I found your board!

Marianne :wink:

How is the Refillable Filter Canister versus a solid Carbon or DI?

And can i add a inline tds meter to my own unit?

What does the inline tester look like?

What is the length of your Great White 9-Stage RO/DI and Mako 5-Stage Reverse Osmosis/ ULTRA Double DI?

Thanks
John

John:

Here is the link to our TDS meter: http://www.aquariumwaterfilters.com/Instruments/TDS.html

I have mine hooked up with the In "T" just after my carbon filter and before the membrane and the Out "T" after my last DI. This way I can compare my raw water to my purified water. You could also connect the In "T" after your membrane to monitor your membrane performance. With my "Great White" I always measure Zero on the outlet and 200-300 on the inlet.

How is the Refillable Filter Canister versus a solid Carbon or DI?

What is the length of your Great White 9-Stage RO/DI and Mako 5-Stage Reverse Osmosis/ ULTRA Double DI? Just trying to see which would fit better!!1

[AquaFX]

The carbon block is very popular. It is in the highest demand. But, I know the granulated carbon is better, and here is why;

The beauty of carbon is its surface area, it is vast to say the least. There is something like 1/4 of a football field (in surface area) in one ounce of carbon. What happens in the making of a carbon block is the binding agent (glue) takes up, up to 40% of this surface area. The benifit of carbon block is no channeling, which can be accomplished by tightly packing the loss carbon.

DI hand packing is fine. The machine packing makes no real difference.

The size of the macko is approx 6 inches wide, 23 inch across and 15 inches high.

The great white is the same deep and the same high (due to the membranes swivel so exact high is varible) and 29 inches across.

If you need more info let me know!

Marianne

[Irisservice]

Thanks for the info.

[Irisservice]

You Carbon media for Refillable Filter Canister is that for one time or more?

[AquaFX]

Are you asking me if the refillable unit is good for more than one refill? If yes, then the answer is yes! You can refill it endless times!

I hope I answered your question! :roll:

Marianne

[Irisservice]

No when you buy your refill carbon is it just enouht to fill it once twice or more

[normd]

The refill supplies enough carbon to fill the canister once. Ditto on the DI. I think you figured out that because it is a refillable canister it can be filled and refilled many times.

BTW, we are having a December sale on filters, cartridges and refills. We also lowered prices on the refillable canister.

Thanks for the quick responce!!!

[AquaFX]

We have single refill packages, but we can put the resin or the carbon together anyway you like. If you want to purchase more then single refills we will give you volume discounts. :D

Now, did I get the question answered :oops:

Thanks!

Marianne

[AquaFX]

The refills are packed for single refills.

Hello Aqua Fx: I am in the market for a boost pump and i see you have the one i am looking for, My incoming pressure in my RO is about 38 psi. Do you still have the 20% discount for members of this forum and how does one go about getting that discount when the order is placed? Should i do it online or call the sales dept directly.
Thank you in advance for your asistance.

[AquaFX]

Thanks for asking, this is a great board, I look forward to see it grow!

You can place the order online and put the discount in the notes. We will subtract it then.

Or you can call us.

What ever is best for YOU!

Happy New Year!

hey aqua, i have a 75 gallon tank and i'm lookin' for a little ... maybe 10g/d ro/di unit... what's the price on a guy like that

[AquaFX]

I can put together a low flow unit for $99.00 plus shipping. The unit will be 25 gallons per day. This will not include a TDS meter which I do recommend.

This is a specail for this board.

[phistio]

wow...perfect for my macro-nano 25!!!

email me with info please! :D

I have a SpectraPure CSP 35 unit which is several years old. I'm sure I need to replace the carbon & sediment filters, and might even need to replace the membrane. I'd like to upgrade to the Hi-S silica removal membrane if possible. What options do you offer, and at what prices?
thanks

[AquaFX]

BoomerD,

It is a funny thing that "high silica" removal membrane. When we first started buliding unit for this industry I looked to DOW, the membrane manufacter. Asked what type of membrane that was. According to DOW (who I feel is THE BEST) there is no such thing.

I have been in water treatment for 20 or so years, I have never heard of a HI-S membrane.

MY feeling on this is, there is no such animal. I believe there maybe something to it (can not find out what it is). It very well maybe a marketing term, instead of a technical term.

So, with all that said. We can replace all your filters, will be glad to have your business!

If anyone knows anything about this "specail" membrane please jump in! Normal membrane remove silicates very effectivly. So I really do not think there is anything to the HS-S membrane

[anemoneman]

I bought the 4 stage unit and got it today, one day before schedule (nice). It comes fully assembled and plumbed. This is a quality unit. I appreciate the steel bracket as opposed to the cheaper plastic ones on ebay. Trust me, you want a metal bracket - it is the only thing that holds the unit up. I piped it to my house water supply in a few minutes and turned it on. No leaks (my house water pressure is 100 psi). It is now producing 0 ppm water and I am more than pleased. I highly recommend these. The folks at AquaFX are more than helpful and are quite willing to work with :wink: the members of this board. I really like the inline TDS meter too. It's nice to see where you're at - coming in and going out. The fittings are push and pull so if you want to replumb the meter in a different configuration its a piece of cake.

I am :mrgreen:

Hi Marianne,

I was thinking of upgrading my existing RO unit by changing the membrane for a better one, but before I could do that the water production dropped drastically. I've changed all the pre-filters, but finally figured it was the storage tank that's lost air pressure. I've tried pumping in air and it's worked great for a day or so, but now it's lost pressure again and I can't seem to pump air through the valve anymore. Does this mean I have to replace the storage tank?

Thanks for any help and advice,
Ken
