Setting Up Dosers

I'm setting up BRS dosing pumps for 2-part and have watched videos, measured pump rates, and still need to determine how much I will dose and how to control it. But for now while I dose by hand, any tips on mounting them? I couldn't find pics of people's mounted pumps.

I think there is enough space in my stand for 2 gallon jugs of solutions. Do people mount the pumps on the inner stand wall? Will they vibrate on the wood and be very noisy? Will they corrode quickly being in salty air? Any reason why inside the stand in pretty close quarters is not a good placement?
 
I mounted mine on the inside of the stand with a small piece of yoga mat between the plastic mounting plate and the 2x4....they slide out easily if you need to move them or service them.

My BRS dosers are also inside the stand above the sump (this hasn’t seemed to affect them the past ~3 years). You can run them at night or times you’re not there to avoid the noise.
 
Got dosers installed in a better spot than originally planned (and only managed to break one drill bit off in the wall of the stand). Plugged into EB8 and ready for me to set up program tonight and roll tomorrow. You are all correct that it is not too difficult.

I tried to set it up for dosing Alk during day hours when student breathing acidifies the tank (arbitrarily chose 6 doses 9am-2pm):
Fallback OFF
Set OFF
OSC 000:00/003:00/057:00 Then ON
If Time 14:03 to 08:59 Then OFF
If pH > 8.40 Then OFF

And Calcium during the night 10pm-3am when no one is there, to avoid extra noise during the day:
Fallback OFF
Set OFF
OSC 000:00/003:00/057:00 Then ON
If Time 03:03 to 21:59 Then OFF

Any concern with this? I do not feel strongly about offsetting Alk and Ca day/night or just staggering by 15 min or # of doses. Today I will hear how noisy pumps are in stand.
Also, on weekends, the low pH occurs during the night so I guess it would be optimal to dose Alk then, but I do not know how to change Apex and I can see how it goes/consult manual and Apex forum if there's an issue.
