It is looking like I have an iron deficiency and I am trying to decide which chelator I need. I have a ph of 7.9 when the lights are out and a ph of 6.5 when the lights are on.
I have been dosing DTPA iron after the lights go out and I am dosing .3ppm a week.
I was having an iron deficiency before and I chanced from ETPA to DTPA and it fixed it. Now I am wondering if I need to go to EDDHA or get an RO unit.
Can I dose DTPA when the CO2 is on and the ph is 6.5 or does it not work that way?
(I'm confident that it is a nutrient problem and not a CO2 problem because it is affecting my floating plants)
Is there also a way to keep the dosing lines clean and algae-free?
