Reverse Osmosis water system
Reverse Osmosis water system
So, I think I am finally going to install an R/O system for my aquarium water. Any recommendations? I found this system, but not sure if there is something better out there without spending a fortune. http://www.bulkreefsupply.com/store/75- ... ystem.html#

Re: Reverse Osmosis water system
What are your tap water parameters? Is this mostly for breeding those soft water shrimp you like?
You don't need a unit with DI for freshwater applications. If you're on a well you'll also need a booster pump to increase your water pressure through the RO filter.
I've dealt with this company in the past and they have excellent customer service and ship in a timely manner.

Yes, it is for my shrimp. I can't get my CRS to breed and I think it is because I have hard well water.Aaron wrote:What are your tap water parameters? Is this mostly for breeding those soft water shrimp you like?

Do you think this is complete overkill? http://www.bulkreefsupply.com/store/pro ... ystem.html
I like it because it includes:
•Pressure Gauge - helps to ensure the RO unit is performing properly
•Flush Kit - helps maintain RO membrane
•Commercial Grade Dual TDS Meter - monitors system performance
•Flow Meter - notifies you when it's time to change filters
•Automatic shut-off valve
And all kinds of fittings so I don't have to make extra trips to Home Depot...
Can someone explain to me the benefit or non-benefit of DI? I couldn't find it explained anywhere.
You are right I will need a pump booster too. My water pressure fluctuates greatly throughout the day.

Re: Reverse Osmosis water system
The DI isn't necessary and needs replacing often. You'd be better off to design your own system with the business I linked you to or see if BRS would for you.
Personally I run a 4 stage setup that goes sediment, carbon, finer carbon, then 2 x 75 gpd RO membranes run in parallel, not series. Whatever you do, don't use 100 gpd membranes. They don't filter nearly as efficiently as the 75 gpd membranes so if you want more capacity just run more 75 gpd membranes in parallel.

Aaron,
Do you cut your R/O water with untreated tap water, or do you add some sort of chemicals to add back the necessary minerals? I've read of folks killing their fish by using pure R/O water....

Re: Reverse Osmosis water system
Hi guys - was following this thread cause I was going to install an RO unit till I found out that I have to pay for water use here in Severna Park - and since I would only get (probably) one gallon for every 6 or 7 gallons of water I pump through the system I started looking for whole house filter systems to get the sediment and chlorine out of the water first - then worry about the other pieces of purification - I saw the last post about hard water so looked up the effects of hard water on RO systems - thought you might want to look at this link for some thoughts on how the hard water will effect your decision on what filtration you might want in the line -

You are fortunate to be on a well since you don't have to pay for water use with an RO system which wastes 80% to 90% of the water through the system (ie, it gets pumped back into the drain) - but since I am on city water and the EPA states that those of us that are subjected to chlorine treated water have a 93% increase in getting cancer over those who are not subjected to chlorine treated water - I need to go to a whole house system to get rid of the chlorine first - in my search I noted several things - an RO system - which is where I started - can't produce near enough GPD for the house (without a 100 or 200 gallon holding tank) - and the filters used in most systems sold in Lowes, or Home Depot or other retail outlets will require changing every two weeks or so - So I am looking at larger filter systems - right now I like the units I have found at the following link -
www.bigbrandwater.com/bigbluesystems.html
the filters are much larger and since for the whole house (toilets - washing machine - showers) I really only need the sediment and carbon filters (to remove the chlorine) I can save the third stage for specific contaminant removal (ie, chloramides, etc) - I can put that filter on the cold water line leading to the kitchen (for cooking) and to my fish room.
Just some thoughts -

Re: Reverse Osmosis water system
Thanks for the info George. I have well water, so it I don't care so much if I waste water. I already have whole house filter in place to remove the big stuff that comes up the well (it is really amazing when I clean it out to see the amount of sand and stuff in the filter), although I probably don't change the filter as often as I should. I have seen clear casings, which would be better than the solid blue casing I have on my whole house filter. It would be nice to visually see when the filter is dirty vs just doing it at a certain interval.

Re: Reverse Osmosis water system
You can probably buy a "glass" housing for your sediment filter so you can visually see what it looks like - I had a glass (or clear plastic) in my last place and could watch the color of the filter change
Re: Reverse Osmosis water system
Yes, that has been on my "next trip to Home Depot" list for a year.
