Neither, I would look at the Spectrapure UPLC-II which is what I own. Uses the same 3 roller peristaltic pump as the LiterMeter, is as easy to program as pushing two buttons and has loads of redundancy and fail safes.

Responded over on Reef Tank.

The carbon block must remove all the chlorine. A TFC RO membrane cannot take any chlorine at all, even 1 ppm will melt it in a matter of gallons.

You should be replacing the sediment filter and carbon block every 6 months and disinfect the system at that time to protect the membrane. Sediment and carbon filters have very little to absolutely nothing to do with TDS, they remove suspended solids, things in the 1 micron range and larger...

When I still had MH I found XM 15k to be the perfect balance. 20k was too blue and not bright enough, 10k was too yellow and 12k was inconsistent. I tried AB, XM, Ushio, Reeflux and Coralife all.

There is no good TDS in tap water. Your goal is always 0 TDS as the things you do want in your system are contained in a good salt mix.

There are advantages and disadvantages. The additional horsepower required to lift water up from a basement is tremendous so you may want to look at power consumption and power bills closely. Along with the additional horsepower load is the heat it creates which may outweigh any cooler...

You will never get an accurate pH of RO/DI water. Since the RO/DI is very agressive, meaning it is always trying to get back to its natural "dirty" state and is attracting anything it can from the container, the air, dirty hands or the TDS meter probe, anything. The pH of the RO/DI is really...

You cannot accurately measure the pH of RO or RO/DI water since they have too few ions to measure. In reality it will be basically neutral and quickly take on the pH of whatever it is added to or is added to it.

In NY the suspended solids will kill a DI filter fast unless you have good pretreatment. NYC has one of the owrst sediment problems in the US due to its water not going through conventional treatment plants. Companies like Spectrapure developed their ZetaZorb pleated prefilter with 10x the...

Its a risk most of us are not willing to take. I am a municipal water treatment plant supervisor and manager by profession and have been for over 35 years and I would never think of using tap water. Tap Water is my business so that should tell you something. Water conditions change and stability...

A TDS meter does not tell you the whole story but its a start. Many substances such as phosphates, silicates and nitrates do not register well on a hobbysist grade TDS meter so can go undetected. It is never advisable to use tap water, carbon treated or otherwise. Think of the amount of money...

Tap water is never advised no matter where you live. Some may have low TDS but can also contain high sediments such as the NYC area or places like the Atlanta area which can be great but change in a heartbeat when big storms blow in. RO/DI above everything else gives you consistency.

RO/DI gives you consistency, you get the same high quality water every time with a properly maintained system. Tap water changes. A storm blows through and treatment changes. The water main down the street bursts or Joe Contractor digs up a water and sewer line running parallel to each other...
