sponges sponges everwhere

[jquailus]

so i have a ton of sponges exploding all over my tank, i think that most are pineapple songes. but there is also some formerian (spelled wrong) my question is could there be a downside to this. i.e. all dying at once and releasing a toxin or sucking up too many nutrients. Ive always been told that they are a good sign of a healthy tank with good water, but i just want to know if there is a downside to them thanks for any input

They will usually go away on their own over time. Don't worry and just keep up good parameters.
