Howdy!
Long story short - I'd like to start dosing some Kalk via apex DoS to my tank. Uptake is roughly .4-.2 daily in alk.
The reason I'm choosing kalk is to hopefully stabilize my pH levels as a benefit. Most days I'm seeing 8.1 at peak to 7.7 at the low, but have seen it scoot down to 7.6 with a full house. I'd like to tighten that bottom number up a little bit more.
First time trying this method so any insight is helpful. I'm assuming the majority of dosing will take place a few hours after lights out, right around 10pm is when I'm seeing pH fall below 7.9.
Anybody running Kalk with an apex care to chime in for a simple program?
I'm also unsure of how much dkh increase I can expect and I apologize if this has been answered but all I've really picked up is "dose and test" which is fine, just curious if there is a "standard"
I could also cut down on the potency to start and see how things react.
My plan - 1gallon of RO/DI and 2tsps to fully saturate, settle and siphon off the clear layer. Ideally I'd like to use some old dosing bottles to house but from my research is seems like I will fly through kalk and will likely need a larger reservoir.
FWIW the main purpose is to supplement lost alkalinity, I'm not shooting for elevated pH levels to increase growth or anything but hoping to put a cap on the low pH maybe 7.9-8
end while supplementing alk.
14 gallon IM Peninsula - mixed reef, almost 7 mos old. Just starting to see coralline take over, SPS growth is minimal if that haha.
Thanks in advance!
