![]() Carbonate hardness and alkalinity are the same thing. And it is a good idea to know where your alk is at. I don't think iodine is all that important. I would get a magnesium test kit before iodine as Mg is needed at proper levels to help maintain calcium and alk.

![]() Calcium, Alk, Mag, these are the 3 big ones that are a must. Nitrate, Phos, and PH are also a good thing to get. Do you use RO/DI water? if not it would be a good idea to start using that. Best thing to maintain these levels are a 2 part Calcium/ALK additive such as E.S.V B-Ionic or C-Balance. The rest IMO is a waste of money.

![]() well my nitrate tested out 0ppm
phosphate was 0.0 or 0.5 it came out this pale light brown colour (which could have been either 0.0 or the 0.5) oddly 0.25 is a yellow colour on the colour card my Alkalinity was 8dkh - ppmKH 143.2 Calcium test took 18drops to turn it blue, so 360-380. |
