How to fix Alk & Calcium and get it steady

[AdamR0331]

Tank is a 20 long 3-4 months old and I do water changes 10-15% every Sunday and store said both my alk and calcium were low here is the amounts

4/2/2023
360PP calcium
Alk 6.5

They Said I should start dosing all for reef is this the correct approach? I have 3-4 euphyilla frog spawn , hammer , leathers , zoas ect ... zoas haven't been opening lately also

Yes, that's a perfectly fine approach. Have test kits to measure both those values. As your coral grows, they will uptake more and more, which will require you to increase your dosage periodically.

What's a safe and easy to use test kit I can get lazy about testing so I typically have store do it even tho I know sometimes can be not 100000% correct since they do so many people a day

I use Salifert for both of those.
