USA thank you!

You can install, just need longer line for the feed water that runs to your sink. Also need to have a drain or get a long enough line to run to a drain. I ran mine into my grow room. Installed a faucet for drinking at the sink and a line with a tee to fill up jugs in the grow area. If you get an...

I think the FC 4800 would be the best option, I have 2 of the FCE4800 and love them! I imagine the FC4800 is even better!

Thank you!

4x8 2 x Mars Hydro FCE4800 Problems in veg with cal/mag. The standard dose makes these girls unhappy with RO water, double the amount (about 5ml) was the fix. Doing great now. End of week 4 flower.

Installed a really good Reverse Osmosis system and a 14 gallon tank. Soooooo much better than buying distilled and precious RO’s I’ve had. Love it. Went with a 14 gallon tank so I won’t run out. Working great! If you need help with getting a water system, I can point you in the right direction.

Very possible it goes through two systems or they have it set up to circle back through the same.

Hello OldMedUser, Awesome, I am glad to help. I am sure the Cat is happy too! lol. I would say on getting down to 2 ppm from having bad feed water, they are running back through. RO is typically a 90% reduction. So that means he is getting the water down to 20 ppm and running back through again...

Also, Just noticed the housing with the plug is labeled UV, that would definitely require power but it looks a lot like a membrane housing. My mistake.

Also, get a TDS meter, you should get 90% out of an RO. So if you are at 400 ppm tds, you should be at 40 ppm after the RO system. The calcite is adding calcium to raise PH so it will add to this. Test at the grow room area to make sure.

Hello OldMedUser, No worries, happy to help, any time I can help make something easier or save you some money I am happy to. Are you running this to a tank or are you looking for it to be "on demand"? The reason I ask this, RO systems are rated in GPD or gallons per day. These smaller RO's are...

Also, if you are getting a reading from a water test or city water report on what the hardness is, if it is not listed in gpg (grains per gallon) it will be in ppm ( parts per million) or mg/l (milligrams per liter). If it is listed in ppm or mg/l they way to convert it to gpg is to divide by...

Hello, I am good, thank you for asking! Less than 1gpg (grain per gallon) is considered soft water Slightly hard 1-3.5 gpg Moderately Hard 3.5-7 gpg Hard 7-10 gpg Very Hard Over 10 gpg When you talk about a water softener with an RO system. For a small under sink model, at that small amount...
