It's some sort of sponge tho and can it affect calcium levels

Picture too purple to see, if it is a sponge it shouldn’t have a significant effect on calcium.

That looks crazy! Can't help but think "Don't feed your tank after midnight!"

If it's a calcareous sponge (a sponge whose spicules - and by extension, skeleton - are made of calcium carbonate - taxonomic class Calcarea), then it would use calcium, and depending on how fast it grows it could potentially affect the calcium level in your tank. However, aside from pineapple sponges (genus Sycon), calcareous sponges are relatively rare in our aquariums (which makes sense since they make up up less than ~5-10% of all known sponge species at the moment).

So, odds are that they shouldn't use a meaningful amount of calcium, but there's a very small chance they may.

My issue isn't low calcium but high calcium I've even switched to a different salt type trying to lower calcium levels all my test are done with Hanna testers I can't seem to figure out how to lower my calcium levels the tank is 3 almost 4 months old now

Yeah, you're not going to find any creatures that'll put calcium into your tank. From what I've heard, the Hanna Calcium Checker is one of the few that gets pretty bad reviews on it, so I'd say to get a second opinion on the calcium (either by testing with a different kit or by having your LFS test your water).

That said, you may want to ask in a different thread why your calcium is high (chemistry isn't my forte at this point, so I at least won't be much help there, but hopefully someone else will be).

 

[I never finish anythi]

The test results are 12 days old .

Thank you for all your help.
