Plating photosynthetic sponges
Hi, I know this issue has been discussed in the past but it doesn't appear to have been discussed frequently.
Does anyone know anything about the photosynthetic plating sponges like the blue sponge available on aquarium depot? Previous forums mostly just discussed whether they grew or not. Are they toxic? Has anyone had them become invasive? Has anyone got them and really regretted it? My sump is full of pineapple sponges, do I still need to dose silicates?
Thanks for any additional info you guys can provide.
