Dropping alk

[nick654377]

My alk has slowly been dropping and wondering how I can bring it up to around 9 again. Used to be at 9.4 and slowly has dropped to 8.5.

This is usually done by dosing a 2 part solution or by another product such as all for reef. Have you ever dosed before or is this a newer tank? Water changes may work for a while if not many corals. Best of luck

Baking soda, sodium bicarbonate, will work. There's numerous products from aquarium supply websites that will work fine.

Run the calculation for how much is used over x amount of days, and use this: https://reefapp.net/en/dosing-calculator

Fill it out, choose a product from the list, and use it as your dosing guide.

I change about 30% once a week. Last night I did 20 gallons in our 65. Alk was 8.7 Wednesday and yesterday changed 20 gal and today its 8.5.
