Aquascaping with driftwood and rock

The short answer: good hardscape is the backbone of a natural-looking tank, and the two building blocks are driftwood and rock. Driftwood adds branching structure and often a soft, tea-coloured tint from tannins, which is harmless. Rock adds mass and caves, but be aware some rocks raise water hardness, which matters here in Southern Alberta where the tap water is already hard. Choose aquarium-safe materials, arrange with a plan rather than filling every corner, and remember that new wood usually needs soaking or weighing down before it will sink.

Working with driftwood

Driftwood gives a tank height and natural lines, and it is the anchor for epiphyte plants like anubias, java fern and moss, which you tie or glue directly to it. Browse the driftwood we carry.

Two things to expect with new wood:

• It floats at first. Most driftwood needs soaking for days to weeks, or wedging under rock, before it is waterlogged enough to sink on its own.
• Tannins. Wood leaches tannins that tint the water like weak tea and can gently lower pH. This is harmless and many fish prefer it. If you want clear water, soak the wood beforehand and change water regularly. Catappa (Indian almond) leaves from our Catappa Canada range have the same tinting, blackwater effect on purpose.

Choosing rock

Rock brings weight, caves and structure, and stacking it well gives fish territory and fry somewhere to hide. The thing to know is that some rocks dissolve slowly and raise hardness and pH. That is helpful for African cichlids, which like hard, alkaline water, but works against soft-water species such as many tetras and dwarf cichlids.

Because Southern Alberta tap water is already on the hard side, be deliberate about adding hardness-raising rock if you keep soft-water fish. Avoid anything metallic, crumbly or of unknown origin. You will find aquarium-safe hardscape and stone in our aquarium decor collection.

Arranging it well

A few simple habits make a scape look intentional:

• Pick one main focal point rather than centring everything.
• Use odd numbers of rocks and vary their sizes.
• Leave open swimming space; resist filling the whole floor.
• Build stable stacks that will not topple onto glass or fish.

Once the hardscape is set, soften it with plants from our live plants collection to tie the whole layout together.
