29-11-09:- Thought I would write a piece every week on my progress with this new 200gl tank. The reason being here in England there seems to be few people who would bother to pass a comment on one`s progress lest they offend. Please feel free to post your views as all comments are appreciated. So here goes, with 110kgs of rock now in the system with all good readings I have decided to add a few clean-up critters. Some Common Hermit and Halloween Crabs, Turbo Snails, Black Brittle Stars and Long Spine Heart Urchin. With no leaks in the system this week (nobody told me you need a flexible tube between the bulkhead and sump pump) I feel confident to proceed with this stage. As always please feel free to comment.
