I apologize, I have tried searching past forums because it seems this *must* have been answered before.
Background: New owner, 350g. I use MPS and dichlor. Water smells clean (i.e., like water, hint of Cl smell). Water is clear.
Aquachek Pro Strips read ~7ppm TC, ~2ppm FC (yeah, I know -- strips)
OTO reads ~2 ppm Cl (read at ~20 s after reagent addition)
I am not sure of my CYA levels, I am guessing ~30-50, but, I was using dichlor per vender instructions before I knew to track total dichlor addition.
My thought was to use dichlor/bleach(after appropriate cya levels reached) to maintain FC and to use MPS after bathers and as a weekly shock.
Instructions from bottle and vendor suggest 1.5oz per application of MPS, but, I am thinking that is quite high now...
I think I currently have a problem figuring out my Cl levels....
** My fear is that I currently have no Cl and I am reading MPS as a false positive on both tests
** OR that I have high CYA that is sequestering the Cl and it is reading at TC (or slow color development on OTO)
Will MPS still affect Cl readings 12 hrs after addition?
How does MPS read on OTO vs FAS-DPD?
How long will MPS remain affecting tests?
I know CYA attenuates Cl
How does CYA affect the OTO/FAS-DPD tests?
-If I add bleach, will it combine with CYA and read as TC vs FC?
-What will the impact be on OTO and/or the test strip reads?
I guess a summary question is:
I have strips that read TC/FC. I have OTO. I have a K2006 kit on order
In each of the measurements, when it says it is measuring "FC" or "TC" or "CYA" etc
How much is it really measuring MPS/FC/CC/CYA??
