I took some of Toms advice and made a really nice cave out of rocks right in the middle of that open space.. java moss wedged and tied on it so itll spread.

Your dead right GMF, its totally transformed the look of the whole tank, even without any growth on it as yet. Im so suprised, its created 2 more rooms in the centre and its totally balanced the tank.

My new CO2 should be here in the nxt few days hopefully, although, according to my drop checker, levels are pretty good at the moment anyway and pretty stable, so its not so bad.

Ive ordered some HC, will see how that goes, there are a few other plants taht ive got that were struggling before, if i junk them, then ill get some glosso to replace them and see how that goes to. Thinking that the best idea is to try smallish bits of a few, and pick the strongest, just as you would in your garden.

Thanks for all the help peeps, much appreciated as always.
