No more pineapple sponges

[daniella3d]

They usually disapear to the profit of other sponges. Mine are all gone as well but I have so many other sponges growing everywhere that I know it's not the water. Surely not the light because pinaple are not photosynthetic and don't care for light at all. They only care for nutrient in the water but for some reason they don't hang very long.

I have tons of pink and blue sponges growing everywhere on my liverock, so I know the tank is healthy for sponges.

The anemone getting bleached is not a good sign. Since they can move around, I am guessing that it does not have too much light or it could move out of the way of the light. It's probably not having enough or the water quality is not right and it has expealed its zooxanthellae. It's really not a good sign.

YOu will need to feed it often since it cannot get its food from symbiotic now. I would check for copper as well.

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?
