I've had a hard time finding a replacement pump for my small indoor fountain.Most pumps either had large rigid cords so they didn't fit in the corner or the pump was loud.This pump has a small, flexible flat cord so the pump slipped into the space easily and the pump is quiet.

HM Digital Waterproof pH Meter Review

HM Digital Waterproof pH Meter
Average Reviews:

(More customer reviews)
I have been using this unit for approx. a month now and so far I am impressed with this unit. Although I purchased this meter for my own personal use, I also work in a professional lab during the day. I compaired this units results with our $1500 meter in the lab and found that this unit is very close in accuracy. The statements about this unit being hard to calibrate are incorect. Having experience with several kinds of pro ph meters I can say with authority that this unit is as easy as it gets to calibrate. I would guess that the other folks here who had trouble probably had defective units. The calibration process is so simple that a person would be hard pressed to screw it up unless you didn't read the manual at all. One other nice feature of this unit is the two decimal point readout. The other units in this price range that are for sale here only have one decimal point display. example-- 7.XXvs. 7.XThis feature will be very helpful to anyone who is considering tight control of the solution you are working with. Remember, for every full point that your ph goes up or down your solution is 10 times more acidic or alkaline. example-- 7 vs. 8 ph. Therefore, with a unit that only reads out to one decimal place, for each number movement your solution is twice as acidic or alkaline example--7.1 vs. 7.2 ph and that isn't even taking into account the margin of inaccuracy in these consumer grade units. The only weakness I have found in this unit is that it has auto shut off and likes to turn itself off while I'm in the middle of a reading. The truth is that it is more of a plus than a minus. Considering that if you forget to turn this thing off, the next time you attempt to use it the batteries will be dead and that would be a much bigger pain in the butt than having to hit the power button once in a while, to say nothing of having to buy a new probe tip prematurely because all probe tips have a useful life based on time of use among other things. The other units in this range may be cheaper but the quality and feature designed into this unit make it worth the extra money.

Watts WP5-50 Premier Five-Stage Manifold Reverse Osmosis Water Treatment System Review

Watts WP5-50 Premier Five-Stage Manifold Reverse Osmosis Water Treatment System
Average Reviews:

(More customer reviews)
For an aspiring indoor hydroponic vegetable gardener like Your Humble Narrator, a source of clean water is essential. Here in suburban Salt Lake City, we are blessed with some of the dirtiest water in the country. Using this meter: pH-EC-TDS Meter my tap water clocks in with a pH of 8.2-8.4 and TDS (Total Dissolved Solids) reading of 300-350 ppm (parts per million). This review specifically addresses the suitability of the Watts WP5-50 reverse osmosis system to the task of providing a water supply for the home hydroponic gardener.
I've used other filtration devices, like straight carbon filters, and have been disappointed. Yes, they do remove sediment and some contaminants, however the drinking water never genuinely tasted "clean". Moreover, taking the testing meter to this water, and the TDS reading never went below 280 ppm which is unacceptable for hydroponic growing. After doing some research, I concluded that the only option was reverse osmosis.

Package Inspection

Out of the box everything looked okay with the exception of the faucet, which, as other reviewers have noted, is a cheaper version of the displayed product.

Installation

Installation was straightforward. The instructions, while not written by an English professor were sufficient albeit vague in a few critical places. I had the unit installed within two hours.

Waste Water, Output Water Quality and Quantity

My three biggest concerns with this product are output water quality, output water quantity and waste water production. Bear in mind that all of these are dependent upon the quality and pressure of your incoming water supply, which can change from season to season as well as from one time of day to another. Take a certain degree of comfort in knowing that my incoming water is probably worse than yours.

I have not yet connected the waste water tube to the sink's drain. Rather, the waste water tube is currently draining into an 18-gallon bucket so I can take measurements for the purposes of this review. To leave this setup in this manner is a code violation. I suggest that you connect your unit properly.

The amount of waste water this unit produces is staggering. For each gallon of clean water, I produce an additional 6.5 gallons of waste water. I have come to understand that I will experience a similar ratio regardless of the reverse osmosis unit I use. This phenomenon is a consequence of RO technology in general rather than a peculiarity of this particular unit. As I've suggested, the amount of waste water produced is proportional to how contaminated your incoming water supply is.

The output water quality is excellent. TDS (total dissolved solids) are 15-20 ppm, which is ideal for hydroponic growing. Any purer than that brings you into the realm of distilled water, which would need to be supplemented with minerals to be suitable for hydroponic use. Output water quantity is sufficient although disappointing. It produces one gallon in about 90 minutes. Higher water pressure and cleaner incoming water will decrease this time. The storage tank, although it has a physical capacity of three gallons, drains to empty after drawing two gallons. I consider this is a consequence of the technology, not a case of misleading advertising.

Summary

The Watts WP5-50 reverse osmosis water treatment system is well suited to the task of providing contaminant-reduced water for the purposes of hydroponic growing. It produces clean water in sufficient quantity for the purposes of a home hydroponic garden. Insofar as the waste water is concerned, for the time being, I'm leaving the waste tube in that eighteen gallon bucket. I'm using that water for my lawn.

June 20, 2009 - Important Update

Several weeks ago, our city's water changed for the worse. I'm assuming that it's because of a switchover to summertime procedures where water consumption is considerably heavier. Incoming water is now 800-900 ppm of Total Dissolved Solids. The unit's output water quality is 80-100 ppm which is still in the "good" range. It now produces roughly twelve gallons of waste water for each gallon of clean water is generates. The lesson here is that water quality can dramatically change from one season to another, as well as from one time of day to another.

During the lifecycle of a single filter, you can save up to 16,000 plastic bottles from being deposited in landfills.
Five-Stage Filtration Removes Contaminants
The Watts RO filters in five stages to ensure that your drinking water is as healthy and clean as possible. Once the system is connected, water passes through a 5-micron sediment filter that traps particulate matter--such as dirt, rust, and silt--that can affect the taste and appearance of your water. Next, a 5-micron carbon block filter reduces chlorine taste and odor, as well as other materials that can give water a bad taste. For the third stage, another 5-micron carbon block filter further reduces chlorine, as well as difficult-to-remove chloramines.
Reverse Osmosis for High-Quality Drinking Water
The system's fourth stage of filtration is especially important, as it involves the passage of water through the reverse osmosis (RO) membrane. This semi-permeable membrane effectively removes arsenic, lead, perchlorate, chromium, copper, TDS (total dissolved solids), sodium, and a long list of other water contaminants. It also removes parasytic cysts, such as giardia and cryptosporidia.
The fifth stage of filtration utilizes a high quality GAC filter, which works as a final polishing filter when the water leaves the storage tank on its way up to your faucet. The end result is consistently great-tasting water at just pennies per gallon.
The Importance of Drinking Clean Water
Water is critical to proper food digestion, kidney health, brain function, blood health, joint functionality, and more. It's important to make sure that the water you drink is devoid of contaminants. Thankfully, using a Watts water filtration device will ensure consistent quality for all of your drinking and cooking needs. In fact, when you use Watts' high-quality certified water treatment devices and filters, your water will be free of chlorine taste and odors, particles, and many other contaminants that can be detrimental to your health.
*Please refer to the Performance Data Sheet for the complete list of claims for which this system is certified.
An Eco-Friendly Choice
Not only is the RO filter a healthy choice for you, but it's also a healthy choice for the environment. This filter helps you minimize the harmful environmental consequences of buying bottled water. Incredibly, if a mere ten percent of North America's bottled water intake were reduced by switching to home-filtered water in reusable containers, we could eliminate:

    133,000 trucks driving an average of 500 miles--saving nearly 12 million gallons of diesel fuel
    Over 100 million pounds of greenhouse gasses--equal to taking 1,100 cars off the road annually
    213 million pounds of PET--equal to 1.5 million barrels of crude oil or improving the PET recycling rate by 10%

Depending upon which Watts water-filtration product you use, you can prevent up to 16,000 half-liter bottles from being deposited in landfills--all in the time it takes to use and replace a single filter.
The Watts Premier Five Stage Reverse Osmosis Water Filtration Device is backed by a three-year limited warranty.
