water change + algae bloom?

[ryanpal]

whenever i do a water change lately..it seems to cause a little bit of an algae bloom. is this normal with all the lawn care chemicals that get into our water this time of year or do i need to check out my RO/DI?

Ryan,

No, your RODI should remove that stuff. Get a TDS meter or borrow one and check out your outflow levels. I would lend you mine, but it's an inline model, permananently installed.
I was getting 3PPM and I recently changed the DI cartridge and I'm getting 0PPM.

im going to replace the carbon cartridges to be safe, but would this be more of an issue with the membrane? i replaced it not too long ago. however i didn't replace it with an actual "kent" one. i purchased one for cheaper on ebay...not sure if that matters but figured i would share

Ryan, what is your TDS out of the filter? No reason to waste money if it's at 0 already.

What kind of salt are you using?
