Hobbyist Line

FMT_RO-DI_line.jpg

 

The FMT Line – Our Full-Featured Hobbyist R.O.

 * From 50 gallons/day to 150 gallons per day

* TFC membranes with 98-99% rejection of minerals

* High nitrate and phosphate rejection so perfect for saltwater reef hobbyists

* Separate 5 micron and carbon block canister type prefilters

* Water Conservation Valve for 2.7:1 ratio of reject to product water

* Can be ordered in well water configuration at no additional cost

Includes: hookup tubing, filter wrench, operator’s manual and a free set of extra prefilters (optional carbon postfilter shown in diagram above adds $15)

The MT Line – Our Most Popular Hobbyist R.O.

We sell more of these than any other RO. line.  They are inexpensive and have the same high rejection TFC membranes as our FMT line.  The single 5 micron rated carbon block prefilter works perfectly for most of our customers.  Unless you have rust or sediment in your water, the MT will do the same job as an FMT and save you money.

 * Economy units from 12 gallons/day to 50 gallons per day

* TFC membranes with 98-99% rejection of minerals

* High nitrate and phosphate rejection so perfect for saltwater reef hobbyists

* Single 5 micron rated carbon block canister type prefilter

Water Conservation Valve for 2.7:1 ratio of reject to product water

* Can be ordered in well water configuration at no additional cost

Includes: hookup tubing, filter wrench, operator’s manual and an extra prefilter.

The RO Line – Our CTA Membrane Hobbyist R.O.

When we introduced the affordable R.O. to the tropical fish hobby in 1986, we sold a lot of CTA membrane units due to their lower cost.  Since then the CTA membrane has fallen out of favor and been largely replaced by the TFC membrane.  Why?  CTA membranes require special water conditions and have certain limitations.

1. Need a municipal chlorinated water supply of less than 300 ppm (about 15 GDH)

2. Cannot be used on a well due to cellulose-based membrane that needs chlorine

3. Lower rejection of minerals (93% vs. 99% for TFC) and shorter membrane life

4. Are poor at nitrate and phosphate rejection so not for saltwater reef hobbyists

5. Are only available in smaller output models due to their larger physical size

 If you don’t need a lot of water, have tap water that is less than 300 ppm., are on a chlorinated municipal supply, and can live with the lower mineral rejection (about 93% vs. 99% for TFC), you may be very happy with a CTA unit.  They cost less and you don’t need to change a carbon prefilter 6-12 months and they take up less space. Hobbyists in the San Francisco Bay Area have tap water that is less than 100 ppm.  The water out of their CTA membrane units comes out at 7 ppm or less. 

* Economy units in 10 gallons/day, 16 gpd, and 20 gpd

* CTA membranes & a single disposabl 5 micron prefilter mounted on top

* Water Conservation Valve for 2.7:1 ratio of reject to product water (the PC10 is the RO10 with a flow port @ 4:1 instead of a Water Conservation Valve)

Includes: hookup tubing, mounting brackets, and operator’s manual.
