Emergency MTRC meeting

[rcmike]

Keith has just left and problem was found within the first few minutes of him being here. A simple $20 or less TDS pen meter found the issue.
Without going into alot of detail at the moment. My water holding container had 350-360tds! The raw water coming out of the faucet is only 2!?!? I thought i had modified my rodi unti to work better but was actually making things alot worse with my modification.

A huge thanks goes to Keith and his family for coming out and helping me find a major problem and i should be able to get things back on track within a couple of months of water changes to drop the tds in my tank.

Glad you found it. Sometimes it is the obvious things that we overlook that cause the most problems. Sometimes it just takes a fresh set of eyes to figure it out.

Wow on the TDS! I knew it wasn't your parameters. But you would think with the TDS that high it would've effected your P04 and N03.

Just a thought, if heavy metals have been deposited in your tank you might have a lasting effect. I would still run the poly filter that Ryan suggested.

Yes do that too the poly filters if I remember right change colors too I think and that may help with finding out what is go in to the tank

Will this work? I have heard of poly pad but never bought any so i want to make sure i get the correct type.

This is it. Poly Filter

I think what you linked to is just a regular filter pad.

 

[schooleyosis]

I don't think so. You need the kind that I linked. There are many impostures so buy the name brand stuff. It might be a little expensive but could lead you to your recovery.

I've nver seen that specific one, this is the only one that I know of Pond Water Quality: Poly Filters Pond Filter Media

Ordered

Thanks

That is the pads I was talking about

 

[p woodard]

And don't freak out if it just turns out brown it will only changes if there is copper or iron in your water

 

[commonstranger]

Greg I was planning on coming down tomorrow. Im proud to see you got the problem fixed. I'll have some free frags for you when you are back on track. We need to hook up soon anyway.

Just throwing this out turf to rattle some brains. But there are swing between day n night in your tank. Have u tested ur water at day n night to see if there's a big swing that could be stressing the sps n killing it off???

 

[greg0385]

I havent tested at nite but i can today. Are you referring to a alk swing and a ph swing?

I dose Kalk at nite only as reccomended to help with ph swings.

But ill test tonight to verify no big swings


Thanks
Greg

Watch your skimmer when you add it. Mine made my skimmer go nuts for a few hours and it overflowed. Glad keith got you fixed up. This is the kind of thing the club should be about.

 

[greg0385]

Will do,

Im so glad people like Keith are in this club. He drove over a hour to get here and wouldnt accept anything in return for his help. I did talk to him on the phone after he left with a small concern. I do 100% agree he is right with its a water quaily issue but the container with the high tds reading is my W/C container. I have read that salt residue can give a high tds reading. I am changing a few things with my RODI unti to help ensure that i am getting 0tds from the unit and the brute container isnt leeching tds back into the water.

I am still open for anyone wants to come down to inspect the tank. Actually it would be great if everyone finds the same problem as Keith did. I seriously doubt anyone could find the issue as fast Keith did though ;) that guy was on a mission straight toward my RODI unit.

If it helps, i am available next weekend too. This way it might be easier for everyone to make arrangement to come down here.

Thanks for everyone's help so far

Greg

Oh, if you have salt residue in the container it will definitely dissolve into the RO/DI water and cause the TDS to go up. Can you test some of the water before it goes into the container?

Definitely this!

And did you guys confirm what your salinity is?

 

[greg0385]

We did, the tds meter was reading 2tds out of the faucet and about the same coming out of the membrane and 0 coming out of my DI chamber.

My dual tds meter reads-14 out of the faucet, 4- out of the membrane, 0 out of the DI chamber.

To clarify a little more into detail. I have Well water, Well water has high CO2 levels which will exhaust DI resin rapidly. So i have made a De-Gassing chamber to resolve this. I have a line coming out of the Membrane that would go into the DI chamber, i have it going into a ACE hardware 32gal container. I let it sit in there for atleast 24hrs with a airstone to drive out the CO2. Then i use a maxijet to pump water through the DI chamber into my 32gallon brute W/C container.

Last nite i did not have any water in the de-gassing container as i had just pump it all into my brute container a few days prior in preparation of doing another W/C.

So when we tested the brute container full RODI water that had been heated to 77F and had a small powerhead for circulation, it read 350-360tds. Our test was to use the maxijet pump to pump that 350tds water back through the DI chamber to see if my recently bought DI resin was already exhausted. We were getting 160tds out of the DI chamber that was reading 350tds.

Without much thought, we agreed that it was the maxijet pumping too much water through the DI resin too fast and pushing debris out of the DI resin into my water, resulting in a high TDS reading.

I am now making new water from the membrane into the de-gassing container which never has had salt in it. I will have results from this in a few hours.


Sorry for the long post, this is why i would rather explain this setup in person as its easier to explain. And im sure i didnt do a very good job explaining it well enough for everyone to understand.


Thanks
Greg

He left his refract at his house so we were not able to confirm my salinty.
