I got the co2 scrubbing media from two little fishes called CDX and it lasted longer than the BRS stuff
I got 5g soda lime from medvet

Any chance you could create a graph of alk + ph like the bottom one with the before picture? curious how pH really effects alkalinity.so to document co2 scrubber improvement via apex.

ok doesn't look like there's a terribly large correlation between alkalinity and pH from that graph. Maybe the amount you dose is based on how much is getting used up? i.e. Trident is controlling the dosing?
You can see as the ph goes up the Alk goes down, alternatively as the ph goes down the alk goes up. Since hes using a CaRX with constant flow, the assumption is there is more alk consumption at higher ph (alk measurement goes down because of consistent replenishment.) This could also be related to light cycle (both alk numbers and ph numbers) i have noticed very similar results though. when ph stays more consistent, alk stays more consistent.ok doesn't look like there's a terribly large correlation between alkalinity and pH from that graph.

Do you think you’ll put any rocks in the front? Or leave it bare for more frags. Did you fill the frag systemsHere’s the tank without sand at front.

I noticed from the trident that changing nutrient levels also significantly affects ALK consumption (peaks and dips) due to growthI mean don't get me wrong, I totally understand the pH/alk relationship, but just look at July 10, there's a mini-spike (before CO2 scrubber I think) of about 7.8 pH and the alk is just over 8.01 in a deep valley, then June 14th when he probably added the scrubber pH peaks at 8.16 but alk barely drops at all to 8.26, then the next two days at the high pH point there is a massive dip in alkalinity that you'd probably expect from higher pH. But if you look at his earlier graphs post #325 3rd graph, in later days the dips once again aren't as big, but not as small as the first. So some theories that come to mind
1: I'm over analyzing this data (this one is a given)
2: The accuracy of the Trident is suspect
3: Corals maybe grow in spurts within spurts, when lights are on obviously, but maybe some days they simply stop growing as much as others
4: Maybe he pulled out some sps on those days so demand on alk decreased
Either way, it's interesting to say the least.
