Does Anemone only tanks need Alkalinity and Calcium dosing?

[pecan2phat]

So I have a few tanks and one in particular is an anemone only tank with clownfish and a few mushroom corals. It's been established for 14 months and currently receives little to no water changes. I did a bunch while the tank was having nuisance algae problems but have stopped since its eradication.
On my larger mixed reef tanks I utilize a doser with ESV 2-part to keep Alk and Ca stable but this anemone themed tank is just a 65g AIO tank so I was keeping the Alk adjusted with Seachem Reef Builder and Ca with Seachem Reef Complete. Over time the tank depletes a steady daily amount of 1/4 tsp of Reef Builder and 2ml of Reef Complete for a value of 8.1 DKH & 420 PPM.
So...... my question is: Do I need to daily dose these 2 components for the anemones?
I'm gathering that the draw is from the coralline algae and maybe a little from CUC inverts. Part of setting up this type of tank was the desire to eliminate or at least cut back on dosing. I also have another 24g cube that is Zoanthid themed and have not needed to regularly dose that tank though that tank exhibits far less coralline algae.

I would keep alk in a suitable range to help keep ph stable. Calcium is not used in large numbers by the anemone. I would just keep the levels at a decent level for coralline

I would say no.
I've always had anemones in my softy tanks and never dose.
Just water changes.

I would maintain them. If the coralline drive values down too much, the anemone may not like it, especially alk.

But you will need a lot less dosing if you keep alk in the 6.5-7 dKH range, which is perfectly fine for an anemone.
