Sps dying. Please help if you can...

[Pimentinha]

No problem. My heaters are off... Still won't get any lower than 79 with ac on.

I thought about dipping them... But the are attached to big rocks...

 

[rambler67]

thats a good reason not to pull them out and dip them.

 

[Pimentinha]

Lol

A simple fan can help keep the tank a degree or two cooler.

Do you have city water or a well?

Do you use a RODI unit and test for TDS?

 

[Pimentinha]

I use city water.

My TDS are around 10 after RODI.

Normal numbers are 170 before RODI

 

[polywise]

10 TDS is very high..
check your DI resin it is probably exhausted.

TDS after the RODI should be 0 to 2max, higher than that and stuff could be getting through into your system. chlorine?

my well water starts in the high 200's and gets to 0 after the unit. I change my DI when I see to getting up to the 2 range (+- every 3 months)

get your unit working better.
my sequence of filters:

1 micron--> .5 micron --> membrane -->DI resin

unstable temp you have there.

 

[Pimentinha]

The temperature doesn't fluctuate between 79 and 83 in the course of one day... It did top 83 on some hotter weeks that we had...

 

[Pimentinha]

Thanks polywise.

i see resin on the DI unit..
How do you tell if it's the DI and not the membrane?

Does it happen to change color when it's exhausted?

 

[piranhapat]

Some DI resin are blue and will turn to brown when exhausted. Sometimes you can just have bad resin in a new DI. If you have TDS meter you can check your Membrane before DI unit and see what your reading. Like Jim said you want it around no higher than 02 after membrane and than after DI your reading 0.

 

[rambler67]

yea 10tds before or after the di is high. i would change the filters out and see what it comes out as you may need to change the membrane or just need to be flushed. 2 tds after the membrane may or may not happen i actually have 6 coming out of my membrane but i also have like 400 tds coming out of the tap.

 

[Pimentinha]

Thanks guy. I'm going to check my membrane and DI resin. You just buy resin right?? No cartridges, correct?

 

[rambler67]

normally you just refill the cartridge that you have.

 

[Pimentinha]

I just checked my Di. It's still full and the same color that's always been... I'm going to take samples to the store to have it checked out. Before and after membrane and after DI...

 

[rambler67]

if you are getting 10 tds after the di ethere its not working or your meter is off i would get it double checked.

 

[lnevo]

If your color hasnt changed at all i think something is wrong...are you sure water is flowing through the resin and not being bypassed somehow

 

[Pimentinha]

Yes, water is flowing thru.
I just got back from the store. I have never used a TDS meter myself so I was unsure of how it worked. The guy at this store said it was 2.27 after membrane and 1.4 after DI.
I'm planning on replacing the filters tonight. The ones before the membrane.

 

[piranhapat]

Your goal is 0 reading after your DI unit. Your getting 1.4 after DI means something wrong with DI resin.

 

[Pimentinha]

I know. I used to have 0. I'm going to look into that.
