Well we tried again today to settle the rocks in place how we went them put to no success. We are going to try again tomorrow and however they set thats how they are going to end up. On a side note our damn heater broke. Damn thing cracked right in half. No it was not out of the water and it was fully submerged. I don't know if it banged against the sides or what. Hopefully the temp wont drop down that much. Also today I looked it in it and see this thing attached to one of the rocks. Its the little brown thing on the rocks in the pic. It was not there yesterday and if it was I did not see it. Can anyone give me an idea as to what it is?
