No more pineapple sponges

[Kit with Cat]

Hi everyone,
Just wondering out of curiosity. When I started my tank, 4-7 months in, I had a whack of pineapple sponges. I was told that's because I had silicates (probably introduced via tap water top ups). Now, 14 months in, not a single pineapple sponge. My anemones used to be brown, then split, and is now colorless. My hammer and frogspawn are also now colorless....am I missing an additive of some sort??

I was using H2Ocean, then switched to Instant Ocean, now I have switched back to H2Ocean. Could this be the culprit?

All other water parameters are in great condition. My reef tank is 90G, with a refugium, running a HOB Remora skimmer, Eheim Classic Canister (2217?) and Rena XP3 Canister, T5 lighting. I dose calcium infrequently.

My livestock in the tank are: 2 false perculas, 1 hippo tang, 1 mandarin, 1 bicolor dottyback (still free if anyone wants to catch him!), 2 fire shrimps, hermits, snails.

Here are pictures....thoughts?
