Thank you.
I have a refugium with a Kessil H80 on it with chaeto.
I also have fresh air lines running to my skimmer.
I don't really want to go the CO2 scrubber route.
I may just see how things go for 3-6 months and monitor growth of corals. If I see decent growth then it's not really a concern. I am at a pH of 8 during the day....I just would have liked it to be around 8.2-8.3 for better coral growth.
I would not recommend relying on Kalk or 2 part to raise the ph to the desired level.

Why not?
I actually do stir around the cheato every once in a while. My P and N's are really low...almost 0 right now still....
3) If the first two you are unable to do, the CO2 scrubber is certainly an alternative. They can be expensive to run if you have too much C02 in your household. The media degrades more if the household needs more filtering (common sense). Also you must remember to add RODI water to the bottom of the reactor of these for them to be more effective.
On mine they state to absolutely not allow the media to get wet and the container has holes in the bottom to allow air to enter and pass through the media.
Not on the reactor I am using and not on another one I considered - ATI do one and Fauna Marin do one and neither require water.Yes you are not allowed to get the media wet, however you need to add a cap-full or two of RODI water to the bottom of the reactor where it isn't touching the media. This could be certain types of a media, I know the one I had from BRS needed this and I found myself adding the cap fulls more often then the media changes.

Interesting. They all use the same media as far as I am aware and both of the ones I mentioned are colour changing - usually starting white and turning purple but sometimes the other way.Awesome, then certain brands require it and others do not. Just things to note I suppose. In all honestly I believe the water in the BRS ones has to do with the color changing media? I could be wrong but I feel that's the reason they require it. I for sure do not claim to know everything, just trying to help where I can.
how do you dose 2 part and kalk.....is that hard to dial in?
No, it isn't hard. What are you dosing now?
I only feel that if you rely solely on this method to raise your PH especially when chasing numbers, I believe it has more of a potential for issues. IE if one decides to increase dosing because of a lower ph then it may toss ALK out of parameter.
Again I am sure that people find success with this, along with everything else in the hobby it is possible to do so. I just wouldn't recommend to anyone to use this as a sole way of raising the ph to the desired level when I believe there are more effective ways of doing so.
I do have to tip my hat and will eat crow if I am wrong about this. I am sure you know far better than I what is effective and what isn't. This is just my opinion on the matter.
BRS 2 part - Alk and Ca and Mg
