what can I use to replace seachem equilibrium?

[SilveRx]

Hi

I currently have soft water in my local tap (less then 7ph), and I currently use seachem equilibrium. I also put crushed coral in my filter and left a bag in the tank.

Is there any other cost effective ways to raise ph and harden the water? I was searching around and came up with dry fertizilers? I have mostly planted tanks anyways may lean into it but just curious what others are using?

 

thanks

You can also add wonder shells https://www.aquariumcoop.com/products/wonder-shell

They help increase hardness and the mineral content of the water
