So, something else......
You know that time we all bought a piece of coral that had a tiny little green mushroom attached to the base, and how we all felt it was nice to get a freebie? and now, that tiny green mushroom is popping up everywhere around the bloody tank ! Ggggrrrrrrrr.
Reading another forum I have in my hands the magic formula to get rid of them. The reasoning goes that stuff like Apstasia X is rather diluted. It has to be to be able to be sold in shops, sent through the post etc, which is one of the reasons that using it can sometimes be a hit or miss. This formula ramps things up a few notches and is apparently lethal, only to be used wearing gloves and goggles!
It goes like this:-
50ml of RO water
2gm Sodium Hydroxide
2gm Calcium Hydroxide
Mixed carefuly, stored in a glass container, and used via the standard type of injector you find in products like Aps X.
I have ordered the stuff and when it arrives I'll let you all know how/if it works.
