RO System

  • We are currently upgrading MFK. thanks! -neo
A storage tank (blue plastic nominal 55gal drum which holds nearly 60gal) can be purchased very inexpensive - I paid $30 for two of them. I connected them with 2” diameter pipe using uniseals, for a whooping $10 extra. This gives me close to 120g of water.

He doesn't have the water stored anywhere. It's a setup that looks just like a canister filter like the one shared in this thread alrdy, hooked up to tap, then to a utility sink. I wish I knew the name of the company he got it from...

The minerals aren't truly my goal. The goal is water w/ no metals, ammonia, chlorine, chloramine, nitrates, the "bad stuff" that's in the tap water. And the convenience of not using chems anymore is a nice thought. (next stop after this post is amazon for more prime, doh)

Can you share a link to a 30$ food grade water drum? The one's I was finding were much more expensive. Honestly, more out of curiosity, since I don't plan on stock piling RO water... Just not something I'm wanting to setup.

(no idea why it wouldn't let me quote everyone but it kept giving me a forum error msg so I had to replace the quotes w/ @)
 
The problem with RO, is that it not only removes the bad stuff, its that it also removes everything else, including the good stuff, leaving a kind of liquid vacuum.
So unless you constantly remineralize for fish like Central Americans, RO can be dangerous.

Which is why I really wish I knew what kind of system he was using, because he literally made a comment about not removing those minerals that CA/SA cichlids benefit from with said setup. Guess I could shoot him a text and ask 'em the company but I'll probably just leave it be. I assumed someone on here would immediately shed some light on it but alas, all I am seeing when researching is standard RO and RODI setups that do not push water like this system in question, and can remove more than you want from the water.
 
I don't quite have a link for the drums I bought, but if one goes into something like the local CraigList (search for "plastic drums"), one will find them available in most regions of the country, in large numbers. One does need to make sure the drums one purchases are ex food use, as opposed to ex chemicals or other nasties. Mine still had stickers describing prior contents as "Apple Juice Concentrate" (from Chile). That in itself is interesting because the drums were made in the USA, so they then went to Chile, and then back to the USA. Go figure!

This is a current listing of drums available in CraigList Philadelphia area (13 bucks each!, as many as one may want) -

Here is a picture of my 2 connected drums (part of my WDS - water delivery system).
Cheers!

the guy could have had an RO unit with a tank hooked up to his sink, you can buy them as a complete unit. or it was just a sediment and carbon filter connected to the sink which is your typical drinking water or whole house filtration setup.
im using both for my tanks; sediment and carbon block filters for auto water changes and then an ro unit to 2x200L barrels.
i got my supplier to setup 2 membranes on the RO to double the output, using the big filter cartridges as a pre filter not just the ones on the RO unit helps increase the rate also.

That appears to be exactly like my RODI unit; except that yours doesn’t have the clear plastic cups, so you can’t see the dirt on the filters and the color changing beads change color.

I have one of those 4 inch diameter filters on my house as well, so there are really two prefilters on mine.

Mostly the RO water does not go into my aquariums except as top off water, and I am typically using it for cooking purposes and drinking purposes.

Of course it’s totally flat so I always put something with it. Usually green tea and honey in my case.

I wonder what was in those drums when they were sent to Chile? I wouldn’t be surprised if we’re sending them drums of powdered milk and they’re sending us back drums of apple juice and grape juice.

I have a similar but even sturdier drum, made of blue and gray plastic, that I use for cleaning rusty car parts. It originally held concentrated orange juice.

But that poly propylene is so inert I don’t think it matters too much as long as you wash it with a little borax or sodium carbonate.

All you really need is a granulated activated carbon filter on your home water supply to remove chlorine (not chloramine).
