Thanks yeah this was a pretty bad weekend surprise.Wow, sympathies and hope you get better!!
Dosing Alk/Calcium is great. Key is that you still need to test and tweak it, even long term.
Usage will vary, so it will drift.
You need something reliable. Not so sure about Jaebo.
For water changes:
If you continuously pump water in + out, those pumps need to match EXACTLY!
You can calibrate, but they need to remain the same as well.
I am not a fan of that method in general, but if you do, seems like you would need really quality equipment.
Given your condition, at least "pump assist" normal water changes. Instead of lugging buckets.
Ideal: Two pumps, two switches, various tubes. One to pump water out, one to pump new water back in.
Simpler: Get a hand cart, put buckets on that, and use a movable pump with a short hose on it.
I have a single head Cole palmer dosing pump but it is probably not going to help me. Just adjustable speed. Would like to program dosing amounts for each and then monitor with tests to.tweak.
Are other brands more accurate than the jebaeo?
Hmm okay maybe simple pump assist water changes are a better idea.
