How to dose Seachem fusion?

[BSej]

Hi all,

I've seen varying opinions on this, and I'm getting confused. Right now my tank holds steady about 8.1dkH and 400ppm Ca. I am dosing Seachem fusion 2 part, but I'm dosing 2.2mL Ca | 5mL Alk per day. I am reading that I should be dosing them in equal parts. How does this work? If I start dosing Ca at 5mL / day, wouldn't my Ca shoot through the roof? Or is it that when I increase my Ca to 5mL / day, the Alk will also rise? So I will need to lower both (for example to 4mL / day)?

first, Seachem did not properly design their product for 1:1 dosing, but the difference is not nearly as large as you note.

What size tank is this?

im also debating switching to AFR, and using my other hose for NoPox. I’m scared to switch though because my setup is working now, and I don’t want to mess it up.

Ok, that volume makes the explantation easy.

5 mL of the calcium part is only boosting calcium by 1 ppm per day. 2.2 is less than half that.

It would take a very long time of dosing to detect a difference by calcium kit.

I’d just do equal parts dosing based on alk, but if not, nothing will go wrong.

AFR is also a fine choice. You need very little of any product.
