RO (reverse-osmosis) filters separate water molecules from other dissolved solids in the water (like carbonates). Pick up your new RO filter here: https://shop.brightagrotech.com/hydro-logic-stealth-ro300-reverse-osmosis-filter-300-gpd/
Basically, the RO filter is a membrane through which water is pumped, sorting through water at a molecular level. Most dissolved solids can’t get through the membrane. This means that the water coming out of the filter is much closer to pure water.
When to use an RO filter
RO filters can be a great investment for farmers who struggle with source water quality. The primary culprit of low source water quality for hydroponics or aquaponics is carbonates. Carbonates act as a buffer, making pH control more difficult for growers. Having a high ppm in your source water to start also interferes with the nutrients you are able to add to the solution.
Source water quality becomes a problem at 200 or 250 ppm. This means that if your source water has a ppm value over 200, you want to think about a filter. If the ppm value is over 250, it’s worth getting one.
What size of RO filter to buy
The RO system in this video is very large. For smaller farmers, there are many smaller RO units that will work fine for you.
How an RO filter works
Siemens’ RO filter has multiple levels of filtration to increase the efficiency.
1 ) Source water enters the system and goes through pre-filter and a sand filter. This filters out the large solids before they reach the finer filters.
2 ) After being filtered for large particles, the water goes through a third filter before being sent to the RO pump.
3 ) The RO pump runs the water to the RO filter itself. Finally, water reaches the RO membranes in the RO filter.
4 ) Each filter sends the filtered water into a large holding tank. The system runs constantly and tops off the holding tank, which is used according to demand.
The 3 main tasks associated with an RO system are:
1- Backflushing filters: Most filters in this system have a backflushing function. Backflushing removes the “gunk” that builds up on the filter, increasing flow and filter lifetime.
2 – Replacing the RO membrane: Membranes can get worn out and efficiency can drop. Check with the filter manufacturer to see their recommended replacement intervals.
3 – Scheduled checks and records: Keep a maintenance sheet to track the efficiency of the pump. For instance, one maintenance entry might have the incoming source water at 433 ppm, and the filtered water at 5.8 ppm. That’s great filtration.

Just a quick look at how you can cut crown mould the easy way. I also show a simple way that you can jazz it up with some mood lighting. Chicks love it.
Post 1/4 million view mandatory description revision:
READ. Because I’m just going to start removing deliberately provocative comments that are not constructive. Lots of arguments about how “there’s only one right way to hang crown mold” on this one, and I, being obstinate, accept the challenge. If you are feeling the compulsion to lay the argumentative smack-down on me, don’t. Evidence is not in your favor. My defense goes something like this: Crown moulding orientation is governed by a set of arbitrary cultural conventions, and as such, the rules and regulation of its application are superseded by the following statement: “form follows function.”
As a person who is competent with respect to design (but not as an authority), I am in possession of the necessary tools to apply my own discretion to its installation. Now you’re probably thinking, “that’s a bunch of commie liberal bullshit. I been puttin up crown for thirty years,” and you may be at least partially correct- but there is still no empirically sound reason that I should have to install it one way or the other. You see, the shape that our present big-box-store crown moulding’s design reflects is one of a simplification of various design elements that were found throughout various cultures of the past; it is a mish-mash. It is a cherry-picked collection that reflects only the design of a product that is engineered to sell in heaping quantities. It is selling you the ideas of sophistication, class, and refined taste- in every single lower middle-class vinyl-coated suburban dwelling in America. Reject your cultural quagmire, and learn to evaluate aesthetics for yourself.
I can go on with this if you’d like: I can give you the spiel on proportion and its relationship to our crown’s dimensions, how aesthetically appealing it is in this case mathematically, and how that has been modified by the placement of the mounted support trim-board, because the placement of the profile’s details no longer appear to be in the same position, but why? Already most of you think that I am pretentious and arrogant, and you’re probably right, considering that I openly admit having to dumb-down my content just to communicate with the majority of you. But I have heard every insult in the book by now, and it’s become tiresome, so why not just be honest? Hey, if you would still like to argue this point, at least use complete sentences. They’re so much easier on my eyes.
In closing: inform yourself, and then decide. But in the process of doing so, spare me (and others) your misinformed tirades in defense of current traditions, which, of course, are maintained by irrational adherence to the old- and not by supporting evidence. It’s simply not just upside-down.
