Not much to report really.
I removed the spray bar to see what effect, if any, the direct nozzle gives on plant growth.
I've also added a few small pieces of Mini Landscape Rock aka Seiryu Stone to the foreground. I simply smashed up a spare piece up with an old axe (eye protection is recommended).
I scrubbed the rocks with a wire brush to remove the stubborn algae. I actually removed each rock and cleaned them individually before replacing into a similar position. I made some very minor adjustments, but I'm not sure if anyone will notice...
It seems my worrying about algae covering the substrate was unnecessary, and the plants remain algae-free also.
So this is somewhat a surprising success so far, as it's now almost 3 months running, and one of the most trouble-free and low maintenance aquascapes I've run so far. Who says you need to plant heavily?!
