a good ro filter for me

[Sad247summer]

I need a good RO filter or whatever i can use to get my water's ppm outta the tap down.
I am running about 250-325 ppm out of the tap and it is getting to be a bitch to have to constantly flush out the excess salt every time I water if I dont want the PH freakin out, even in a res with mixed GH 3 part and air stones the ph still goes up @ least 1.0 point per day.
We did the mr clean carwash thing, but it is geting to be a pain, I just want a decent filter that I can run off a float valve. The MR clean water was great, but I had to add alot of ph Up when I mixed the food with the processed water the PH was definetly more stable.
DO I even need a ro filter? can I just get a inline sediment filter with the expensive filter.
Help me please, Model numbers, Pix, personal experience, thx for your help!
Ohhh yeah I would rather it does not waste a shitton of water

I bought a 3 stage unit from e-bay for around or under 100 and it brings my 300ppm tap to 0.

All ROs waste a shitton of water, it's the nature of the beast.

If you want stable ph you definitely need RO water. It will start with a stable nuetral or slightly low ph, but any good chelated nutes should stay stable in it for quite a while. A sediment filter will ONLY filter particulate matter from the water. A good RO system will have a mesh prefilter and carbon. Both are vital to keep an RO system working right. Get the right stuff.....nothing will beat the RO.

Oh, the real low ph of the Mr Clean water is probably because it's DI (de-ionized) water. That will be PURE and have a much lower ph and conductivity. This is why most people use an RO filter and not a DI filter.

Get one on ebay, hook it to your float valve and no more worries. Remember, the nature of an RO filter is to eject most of the bad stuff OUT of the filter with the water. This is why waste is high. There's no getting around it if you want good water.

I got the Apec RO-45 five stage 45 GPD unit for 300 dollars.Except for co2 enricment its the single biggest improvement I can think of in my grows.

Check out the link below.
The thread below details how to take apart and convert the "MrClean AutoDry" car washing system. It is really just a fancy sprayer with a "PUR" water filter in it.
There is no need to make all the modifications that people in the thread made. All you have to do is remove the nozzle that restricts the filtered water flow. I personally like the feel and functionality of the sprayer so I left it in tact. I only used a drill bit and pliers to remove the nozzle head that was constricting the flow of water from the filter.

I tried mr clean and it works fantastic but I need more water without dragging the hose inside.
Am I going to be better off buying a RO filter system that uses RESIN or does not use Resin?(if that is possible)
Thx

RO filters don't use resin. They are a specially woven mesh material that separates the bad stuff from the water. The resins you're talking about will either be a cation or anion resin in separate filters or as a mixed bed. De-ionizing filters will usually have a mixed bed of resin but that may be preceded by individual cation and anion filters in some cases. There are units that are JUST RO filters and some that are RO/DI filters. In either case they will both most likely have a particulate mesh filter and a carbon filter at the least preceding the RO/DI. All you need is an RO filter system. You don't need one that produces de-ionized water.

Hope that helps.

ok 2 more Q's
How about some more specific model #'s
and is using a RO+DI filter a problem cause the standalone ro units are more expensive.

No, it's not really a problem. DI water is a little voracious though, so depending on your nutes, you might need to temper it by adding a small amount of tap water to it. Without going into all the technical stuff, the purity of DI water can cause some nutes to lock out, etc. I use BC Technaflora nutes and I don't have any issues with my RO/DI filter. Ph will start off a little lower with DI water too, but again, type of nutes will determine if this is an issue or not..to curb any issues do the tap water deal. You can do 1/4 tap water 3/4 DI. I would be sure the tap water has sat for at least 24 hours to evaporate any chlorine before using for plants. Good luck!
