Jac, your aquarium is amazing! What an extraordinary addition to a home. Your house is lovely too!!Sam,
many thanks. I have been trying to get this sort of feedback, and will keep reading, asking, to be able to pull the trigger on a final set up.
I was able to get 2 IBCs of new water the last 2 nights, and one more I hope tinight, so we may be in a position to do a big water change on Friday evening or Saturday. The plan is to do at least 60% water change, and that should tell us how bad the leaching is. I hope after more than 3 weeks soaking, we have seen the worst of it.
Yep, I do have a lan B ready - I used fiberglass rods and silicon to gradually glue together 4 of the Fiji rocks we used for the aquascape, into a 600mm long stepped ledge. It could replace the driftwood over the drop off, but Zi will need to re-position a few base rocks to weigh down and anchor this cantelever.

I was reading about some different LEDs and came across Orphek. Their Atlantik 4 seems to be quite exceptional for its size and price. It’s $899 US ($1100-ish AUD).

They make lights for large aquariums and they seem to do the job.
