Help getting 2 part dosing straight

So what is the main concern?

Is it that you really want to get to higher alk than 8.6 dKH, or that you are concerned that you are getting precipitation and may be wasting additive?

In the first place I don't have the knowledge or the experience to know what I really want. I just try to read and learn so I can have a nice reef aquarium that I can be proud of. I came up with 9 dKH for the alk from reading and I will admit the 440 ppm for Calcium was that more is better mentality. But no I don't see any sign's of precipitation. I am just trying to do what you guys that have allot more experience say because it works. So as I stand right now dosing 25ml of each alk and cal I started with 8.6 dKH and 420 ppm after 24hrs #'s went down to 8.2 dKH and 415 ppm. 7pm tonite will be the second 24hr period could you give me your recommendation?
 
I generally recommend alkalinity in the 7-11 dKH range.

Higher alk in that range can lead to faster hard coral growth, if these is sufficient nitrate and phosphate (maybe other things).

Lower alk in that range makes it less likely to get SPS burnt tips if the nutrients get too low.

I would not suggest that 9 dKH is "better" than 8 dKH or 7 dKH.

One fine plan is to keep dosing as you are and see where the alk settles out.

An alternate plan is to dose 50% more each day and see where that settles out, which will be a somewhat higher alk than the above plan. :)

In each case, I'd use the matching dose of calcium. :)

I am going with the alternate plan and let it run that way for the weekend and see where it settles out
I will keep this thread updated.

`

So would you say that higher alk can lead to faster growth but with that faster growth you will need to monitor nitrate and phosphate closer. I have subscribed to the guide lines of keeping my nitrates between 2 and 10 ppm and they have been running around 5/6ppm. Phosphate .03 and .06 last I checked it was .02. While on the subject of faster coral growth I know the lighting plays a big role and thats something I need to get better but am working on it. But how do you tell if the flow in and around your reef is good? Are there tell tale things you can look for of ways to gauge the flow in and around your reef.

Those values are fine, but if it did start to go lower, then you'd want to monitor more frequently at higher alk.

Flow is pretty hard to judge, and the need depends on the organisms present. My suggestion is to look at videos of folks tanks with similar creatures.

I have and will continue to but at the same time here's the problem I have now. I am using a Maxspect Gyre and it's running in random mode but for the life of me I can't figure out why this is happing. I believe they are air bubbles but why? Any help would be appreciated.
On my dosing I have it set to dose on a 24hr schedule of 37 ml which works out to be around 1/2 ml per gallon and my alk has been running 8.6-8.8 dKH and Calcium seems to stay around 415-420 ppm

That one was just about the air bubbles or what ever is causing it? I will post another
 
If there is not air getting sucked down into the pump (sometimes there's a tiny whirlpool that sucks in air), then bubbles can form during the day if the water is supersaturated with O2 and the pump brings the O2 back to the gas phase, or simply that gas bubbles can form in the pump by cavitation.
