So I scrubbed my LR today and was wondering....
I scrubbed all the dark blackish stuff off which came off pretty easy and muddied up the water in the tub pretty quickly, but I didn't know how much more I should keep scrubbin'. I gave each rock a once over and concentrated on the black patches, but found that the white stuff never came off and looked the same after scrubbing. I presume its mostly calcified? Is that correct?
secondly, I have lots of nice coloured (lime greenish) coraline with white spots on it. I didn't want to scrub off the coraline so I just gave it a quick and light brushing. then there are what I think are sponges, but it was very hard, it has turned white from its original green colour, but i can't scrub it off....it needs to be chipped off.....should i just leave it on?
Most of the rocks were almost without smell, but some of the bigger ones had some definite funk to them and I think there's lots rotting in the little holes and caverns that I can't get into.... am I fine just to leave it all as I've done?
