My RO/DI MaxCap UHE system

mga345 · 03/21/2009, 10:57 AM

Hi,
My name is Moshe and I've been running my UHE RO/DI system for 3 months now and I am very satisfied with it.
I live in Israel and as far as I know, I am the only reefer that have this system. That is why I post here, to look for information and answers to some questions that I have.
Please take a look at the link, because one of my questions will refer to the photos there.
http://picasaweb.google.com/mga345/OsmoticSysem#

I have a 125G reef tank + 40G samp and also a freshwater tank (about 55G).
I do a 10-15% water change every week so I need about 150G (max.) of pure water, per month.
I would like to know when (approximately) I have to change my sediment and carbon filters, as well as the DI filters. In the pictures, you can see the measurements on the TDS meter. The temperature at my place is around 75-77, most of the year but sometimes can go up or down a little.
I guess that I have to purchase the filters abroad (I don't think that we have them in my country) and I would like to have spare one in hand.
About the DI changing, can I get the resin only? how long can I keep it and under what conditions?

Now, to my other question:
If you look at the third picture from the left (in the link above), what is the 5/8 blue tube and what should I do with it?
So far, I haven't done anything with it.

Thank you in advance.

Hello Moshe,

Last question first. I hope you have our latest instructions manual. If not, please download it here:

http://spectrapure.com/manuals/PRINT...DLY/MC-UHE.pdf

The tube is identified as "Pure Water Flush to 3/8" Bulkhead". Pages 6 & 7 show that a 3/8" blue tube should be connected from the bottom fitting on your blue tank (photo #12 and page 7) up to the 3/8" line with the check valve attached (photos #2 & #3 and page 6).

It is not connected at the system, and I cannot see where it does connect. I see it in photo #12 and also in photo #6, but it disappears from view in photos #2,3,4 & 5.

I see a blue line that leaves the right side of the system and loops back up into the system in photo #12, but I'm not sure what that is.

I should be warning you that this voids the warranty, but I'm sure you have caught it in time, because your input water is 593 and the RO water is 003. That is a 99.4% rejection ratio, another excellent SpectraPure SpectraSelect Membrane and all is well.

Locate the Pressure Regulator, pull the grey knob up and adjust the system pressure to 80 psi.

Your pre-filters are going to last a very long time. If you have made 150 gallons then only 300 gallons (instead of 750 gallons) have gone through them. The Zeta-Zorb has a huge capacity for trapping dirt and the carbon is good for as much as 20,000 gallons. The time to change the pre-filters is when you can no longer maintain 80 psi on the pressure gauge.

The MaxCap DI only has 3 ppm going to it -- a very small load. Again, it will be a long time before you will need to change the DI carts. You can let the output of the MaxCap reach 003 before changing it. ~Eventually~ after replacing 3 MaxCaps, the output of the SilicaBuster will stop being 000 and then you will change it.

Hi Scott,

Thanks for the quick reply.
The pure water flush 3/8" to bulk head tube is connected as directed to the bulk head in my container.
The reason that you didn't see it is because I used it at that time for taking small amount of water from the container (by gravity).
I understand that this tube must be connected all the time because the operation of the flush cycle is done automaticly (page #4).
As you could see in one of my photos, the pressure is 80 psi when the system works.
I did everything like it says in the manual (I have the instructions).

As I understood, I don't need to prepare a new set of filters now, because I don't use much pure water. I just wanted to emphasise that I live in Israel and when I'll need the filters, I would have to wait few weeks before I can get them.

Another information that I want to share with you is that I spread my experience with my new system with all our local forums ("Reef Center" and "Aqua") and I believe that I will not be the only one in Israel to use this wonderful RO/DI system.

Then I haven't answered your original question.

Answer: I don't know what 5/8" tube you are referring to. All I see is the 3/8" tube with the check valve on it and you know it is the Pure Water Flush tube.

Your pressure read just under 80 psi and that's why I asked that it be set to 80 psi so you would know when it actually started to drop due to plugged pre-filters.

We have no dealers in Israel, so yes, you will eventually have to order them from us. By then, we may have a plan to sell the MaxCap resin in bulk, but not at the moment.

Thank you for spreading the word, you might be able to put together a group buy someday soon!

Hi Scott,

Sorry for my mistake. The blue tube is 3/8" of course, and I connected it as directed.
The pressure stays always at 80 psi during operation and I have no problem with that.

I guess that when you start your plan to sell the MaxCap resin in bulk, there will be a message in this forum and in the site. As I understand, I have enough time for that according my rate of use.

If you will ever get a message of interest in SpectraPure systems, from people in Israel, please remember and direct them to me. Then we can put together a group buy someday.

Thank you again for your help and advices.

Moshe Gur-arie-
thank you for your kind words regarding your experiences with our UHE system!
If you put together a group buy let me know and I will help you with a special deal for our many good friends in Israel.

I thought I would comment on a practice I use on my system---- I keep a set of filters at home stored in a cool dry place so I always have a replacemenmt set on hand. I do this with all my vehicles too (oil filters and other consumables) as it seems that when I really need something as simple as a filter (for my water system, or for my vehicles, doesn't matter) I want to be able to take care of it then, not later. So, my personal policy is to keep spares of common consumables rather than be waiting on the mail for something I may need fairly immediately to keep whatever running. Seeing how water replacement is critical to your tank, I think a emergency back up mentality would be valuable. I know some of our serious reefers here actually have a back up RO system for "just in case". Me, I like to have the parts to rebuild the whole thing just in case!

enjoy!

Thank you, Bruce.

In the near future, I will place my order for a set of prefilters and I hope that by then you will have the DI resin in bulk, so I can put that also in my order.

As for back up, I have three 20G plastic barrels and that shuld be enough for an emergency.
