Ro/di blues

[Evilweevil]

So have had the tank running awhile been using the aqua fx barracuda ro/di unit it has been running at about 25 - 27 psi since I hooked it up ... Yes I know it's low anyway I just bought a dual tds meter ( which for how cheap they are I should have bought one right away doh!!) anyway the tds is reading 220 in and even higher out ? Wtf ? Yes I could have the things the wrong way ( they say IN and OUT very clearly though ) no matter it is still out to lunch not sure what steps to take

Tank is looking good very small amount of hair algae and diatoms (brownish kinda algae that grows on the sand appears and disappears with the lights and feeds on silicates I believe?) which I think maybe becoming from my water woes

I am a newbie so feel free to correct me on anything I say here lol which I am sure no one has a problem with

My first reaction was to go out and replace all the filters which I bought all but the di filter from Home Depot which I am going to return anyway ,then I went online priced out all good quality replacment filters new DI new RO carbon block and prefilter , along with a booster pump and back flush valve which brings me to over 200.00$ , would I be better off just going and buying a unit like the vertex aquaristic for 320$ http://www.jlaquatics.com/product/vt...+-+100GPD.html any noughts on this or ideas ?

Any help would be appreciated

It must be hooked up wrong if its new and has higher tds out than in.
Did you flush and throw away the first 5 gals of water?

Pics would help us to see how you have it hooked up

27 psi is low pressure is that your incoming pressure? RO/DI needs at least 60 psi to function properly

Your cartridges are defiantly toast I have 2 of the vertex units and love them. It's up to you if you want to upgrade the system. The vertex auto flushes the ro membrane on shut down and startup if you unplug it when it's not in use.

Yes I know the pressure was low its actually at 20 it's dropped that's why I was looking into buying the booster
Here's a pic of it although most of the lines are hidden http://s1359.beta.photobucket.com/us...dfc62.jpg.html
I have checked and believe it to be all hooked up right

How much is going to drain?use a measuring cup and a stop watch.post volume at the 1 minute mark.

The filter was installed upside down. Turn it around and TDS will be zero. j/k

However if your in the market for a full system I bought mine from maxwater and happy. (don't own their stock or have anything to gain)

Lol ckmullin it very well might be

So I did the test and the production line was 1.5 liters and the waste was .5 liters so does that mean the production and waste lines are reversed ? If so it was that way from the factory man I really wish I would have bought a tds meter right off the bat ....that's what you get for buying at big als with out doing your homework first

I'm not no ro expert but 1/3 is the rough ratio...1 good 3 bad though.

Yes ckmullin is correct, you should have 1litre good to 3-4 litres waste water

Your sediment filter does not seem dirty. Mine is a lot dirtier, way more dirtier when my pressure goes down. If you can, check the pressure after the DI while it is making water.

Can't see enough of the lines to be able to make a judgement if everything is ok. But I suspect it is reversed as ckmullin pointed out.

A booster pump will help you out a lot.
