Can anyone recommend a good cheap Reverse Osmosis Fitration System?

Anything you can get your hands on without paying for shipping! haha.

I had a saltwater tank that I used 9 canisters for, and two RO membranes. - I still have the system, but I dont use it at all anymore... Problem is, I always expect to use it eventually again and cant bear the thought of selling it off haha.

YOu can also build one using parts - contact a local water/plumbing/irrigation store, they will likely have some pre-fabbed ones, and a technician who could build you one to your requirements.

I have a feeling lower mainland water is all surface water? Should/could be A-okay for CPs

My well water is like the drippings from the ceiling of a limestone cave. I don't know the availability in Canada (sorry) but I bought an iSpring Ro filter 7 years ago. It died recently, and I bought another. It's been easy to maintain, and delivered <10ppm water under high use for th time I owned it. Cost something like $200US.

That said, there was someone here years back who had a home distillation system who loved it. Just another option, I suppose.

Good luck.

I used a distillation device for years. It's very cheap in Toronto where the power is 1/3 at night. I think it was 19¢/L after the CAD$99 cost. Now I just collect rainwater in the fall/spring and use it up over the summer.

Any of best seller on amazon for RO system worked for my family (not same household) never used the water for CPs since they are not driving distence but I tested the TDS and it was at 15-20 which was good enough for the price (on sale for $100).

I use this one. It's rated with a 1:2 pure to waste water ratio but I haven't measured it. It's probably not running efficiently since I have some water leaking due to the adapter I have to attach to the faucet. The total dissolved solids reading is 0 PPM after filtration.

This is very silly question. But I cannot get the water acidic enough in my terria for my Uts & D hams. Think it’s down to the dollar store pebbles and the distilled water in there. I know me and mr Lloyd was talking rain water. I have no clue about this water system In this post.

I’m thinking of getting rid of water in there. And just collecting rain water in a bucket or snow? And then adding 1nch of it to my terria.
Is this safe to do so?

this is my reading at 8.77ph.

cheers

Where do you get your fresh water for CP's? You could put some of your fresh CP water in a cup with some of the stones and measure the pH. You have to be careful with stones/rocks. Unless they're pure quartz gravel you never know what they'll leach. I let my pots just sit on the terrarium bottom or in little dishes if I want to independently regulate the water level.

Cheers for the reply!
Fresh Water. ?

l used distilled water and I feel pebbles have some chemical or something on them.
I got dollar store pebbles.

i have had some of plants sitting in it. I’m suprises I Gibba still growing

how would I get this acid for the U Gibba and Hams to be good?

I was just thinking of removing the pebbles and current water and waiting for next rain or snow full getting a bucket outside then add that to the tank 1inch so the purest of water (rainwater) in there. Then water my Nepenthes and little water run off from the bottom of pots seep into the the terria water for nurtrients.

shall I just keep the bottom substrate free or add some kind of Fluval sctrum?

whst did you do @Lloyd Gordon ?

It is rare but possible to have soft (i.e. low mineral content) water that has a high pH. I have a planted aquarium with water that has a TDS (total dissolved solids) of 90 parts per million (ppm) and a pH of 8.2. That's not the softest water, but it's not particularly hard either. I'd suggest you get a decent TDS reading of the water in the tank. I suspect the TDS will have a larger bearing on your plants' conditions than the pH will necessarily.

In regards to your U. gibba, I grow mine in the waste from my RO filter. The TDS of that sits around 430ppm. Enough that calcium salts precipitate out. Been doing it for years. Grows better there than in the RO water. I would describe U. gibba as fairly hardy, in my experience.

Thank you, not after anything fancy etc just yet like that RO system.
Just wanting the water more pure for the plants like rain water and get them pebbles removed I got from dollar store - as I feel the pebbles might have caused some interference in water table even my u Gibba are doing good my D hams seem to feel it.
Im probably overthink but I just want to be sure and have pure fresh water in there (rainwater /acidic I haven’t got A TDS meter but should look into that. However I do know that distilled water should read under 7ph as it comes in contact with Co2 in the atmosphere.

My weather is slight hard but neutral atm.

Thinking of adding light substate at bottom of the terra like Flaval Stratum as
It’s good buffer 6.5 slightly acidic with distilled water then that way I can grow my u Gibba and D hAms. Root systems might love that and have my pots sitting in that

Measuring the pH of distilled (or very pure water doesn't really tell you anything. Because it has no buffer, the slightest change can vary it a lot.

Oooh! As long as it’s good in my terria for hams to grow and U Gibba in long run. I went you style tank Lloyd.

Shal I add the flaval substrate too the bottom tank? I thinking about it for looks and for it to buffer the Distilled water slight more acidic. To like 6.5.

Fluval Stratum is a substrate that is meant to provide root available nutrients to aquascape a planted tank. As such, it is likely to do far more harm than good as CP typically do not want high nutrients available to them. If you want/need a layer to elevate pots at the bottom of a tank for CP growing, think inert. Marbles work well if you can get a solid layer. I don't know the name for them but the squished shaped marbles that people use like little fake pebbles work well too. Anything that doesn't react. Both of these can be inexpensive options as a bonus.

damn! I just ordered Flaval off Amazon :rolleyes:
So this is no go then????
it says it gives an acidic PH of 6.5 to water.
So I thought I would be good for the U Gibba and Hams and sit my SARRS & Cephs in?
I just wanted something to look good at bottom of terria as well as help the plants get nutrients. I guess flaval is out

I’m waiting for it to rain tomorrow so I can collect it in the bucket and add it in the tank with a new substrate that will keep water table at 6.5 low ph best for my plants especially for U Gibba and D. Hams to grow, my Neps will be elevated but my sarr, Cephs and dews will pots will be in it. :D

I do have big bag of Lecca (clay hydro balls) laying around I certainly now these are neutral and won’t interfere with water table.
This could be option as substrate layer for the rain water.

Just a note, I know many people who use Fluval stratum as their sole media for Heliamphora and Nepenthes (they grow N. rajah and the like in stratum so not cheap neps either). Stratum is absolutely horrible as an aquarium soil since it has virtually no nutrients at all, but that makes it excellent for carnivores. Only real downside to stratum is it's price.

@MimiStew24 should not have any issues using it.
