PH should be at 8.2-8.4 so you are very low..water changes or a PH buffer is needed to bring it up.
Also the sponges are harmless filter feeders...but the anemones are called aptasia and are stinging bad corals. They will over run your tank...get a prduct called aptasia X, Joes juice or inject it with boiling water from a syringe without a needle...like they use for giving babies medicine, you can get it from any drug store.

scratch the boiling water and get aptasia x or joes juice. i used boiling water and one released its eggs apparently, a week later it was way worse. and also, as long as there are not to many and they arent stinging anything, they give a cool look to the tank in my opinion.
