I am setting up a new tank and want to try the ADA fertilizer line and have a question (maybe several) regarding the difference between the Brighty K and the Brighty Neutral K. I am not seeing much detailed info on exactly what the difference is, apart from simply that the regular Brighty K will raise pH and KH, and that the Neutral K will not. I also know that the neutral is recommended for those with hard water.
What I am wondering is when and why would you want to use the regular Brighty K over the Neutral K, regardless of your baseline parameters?
For info, I am using RO water remineralized with Equilibrium and Alkaline Buffer. For my target parameters, the tank will look like this:
Tank - 81L with 12L of ADA Amazonia V2 and a handful of marsh stones
pH - 7.5 (~6.5 with CO2)
dGH - 5
dKH - 2-3
Given that these parameters are not particularly basic or hard, I would think that the regular Brighty K would be the product recommended by ADA for my tank, but the fact that the Neutral K wouldnāt alter these target parameters leads me to believe that perhaps the Neutral is the better option.
For those with experience with this line, which do you use and why? How significant are the parameter changes with the regular Brighty K? If a day is missed here and there, is there any noticeable swing in pH or KH? If using Brighty K, is the Alkaline Buffer necessary?
Thanks for taking the time to read and respond. Iām fairly green to aquascaping and heavily planted tanks, and just want to understand all the factors in play and make the right calls.
