(Earth Sciences / Geological Science) an accumulation of weathered rock fragments at the foot of a cliff or hillside, often forming a sloping heap Also called talus
Inspired by a recent mountaineering expedition to Snowdonia.
This is my third attempt at an Iwagumi, and I think it has potential. I think it's the strongest use of hardscape I've used in any design so far.
This dry run with the hardscape has been set up in a 60x30x30cm, but I will be transferring it into a 60x30x36cm opti-white.
There's a couple of minor alterations I need to make, including more attention to detail with the graded gravels, but you can see the effect I am after. The extra 6cm in height with the opti-white will also need to be taken into consideration.
Planting will be minimal with Eleocharis acicularis in the background and probably nothing else.
I've used E. acicularis before as a background and it provides a great backdrop in the appropriate setting; such much better than E. parvula that stays shorter and has a thicker leaf.
I'll be running just one 24w HO T5 along the back of the tank, due to the relatively low plant biomass. Photoperiod will also be minimised to prevent algae build-up on the rocks and gravels/sands, and I'll also dose Liquid Carbon to help minimise algae.
I'm undecided on fish but am considering Sawbwa resplendens, as these thrive in hard water and suit this layout; their body colour complimenting the rocks and gravel, but their head and tail providing a desirable subtle splash of colour.
