8ph and low alkalinity

[benyseven]

I recently set up a 60l nano with established media and live rock from my other tank. Tank has been running 1 week with 2 clowns and 2 lps couple of zoas. Tested my water today ammonia nitrite 0 nitrate 2.5 dkh5 ph8 and calcium 380 salinity .023 My corals look good and all open. Is this drop in alkalinity expected even with using established media? How should I go about raising?
Thank you

I'd use Sodium Bicarbonate to raise your Alk.

I don't know if 5 dKH is likely to be accurate (seems suspiciously low), but if it is, baking soda is a fine plan,.

Hello thank you for your replies, it turns out my Red Sea test kit doesn’t work properly as my lfs tested 9

Sounds good.

Happy Reefing.
