I am starting a new 150 tank and ordered 350 lbs of live rock. There was a ton of growth on the rock when it was delivered. I pulled off the huge stuff but there is a lot of growth that is dying.....to be expected should I remove the excess plantand dying alge growth. the ammonia inthetank is high 2-3 ppm i have been doing water changes but the ammonia is high. I would think the extra die off is adding to this.
