Plants

Hardscape is the rock and wood that gives a scape its structure, and getting it right matters more than any plant you add, because it is the part you cannot easily change later. Most guides talk about hardscape purely as design. They skip the thing that has caught me out more than once: some rock quietly changes your water chemistry. On my hard tap that is sometimes a feature and sometimes a fault, and which one depends entirely on what you are trying to keep. So this covers both, the look and the chemistry. ...

The lush green lawn across the front of a tank is the thing most people want from aquascaping, and it is the thing most people fail at, because the carpets in the photos are almost always grown with pressurised CO2 and strong light. Take those away and most famous carpeting plants either grow tall and leggy reaching for light, or melt away entirely. So before you spend money, here is the honest version: what actually carpets without CO2, what will not, and how I get a low green foreground on hard alkaline tap water. ...

Aquascaping looks like a dark art from the outside, all competition tanks and Japanese design theory, but the working version is much simpler than the photos suggest. It is arranging hardscape and plants so a tank looks deliberate rather than accidental, then giving it time to fill in. You do not need pressurised CO2, a nature-aquarium philosophy or an expensive light to make a tank that looks good. You need a plan before you start, patience while it grows, and a willingness to accept what your water will actually support. Here is how I approach it. ...

There is a persistent worry among new keepers with hard tap water that plants are simply not going to work for them, that a lush green tank is something reserved for people with soft, acidic water and a cylinder of CO2 bubbling away. I had the same fear when I started, staring at water that measures around 22.5 dGH and assuming everything would sulk. It turned out to be almost entirely unfounded. The great majority of the plants sold in shops grow perfectly well in hard alkaline water, and several of the toughest actively prefer it. This is the list I would hand anyone setting up a low-tech planted tank on water like ours. ...

The single best upgrade I ever made to my fishkeeping was not a fancy filter or a bigger tank. It was a scraggly bunch of java fern tied to a piece of bogwood with cotton thread. Within a couple of months the tank looked alive rather than decorated, the algae on the glass slowed right down, and my water tests got boring in the best possible way. If you have been putting off live plants because you think they need pressurised CO2, blazing lights and a chemistry degree, I want to talk you out of that idea. A low-tech planted tank is cheap, forgiving, and honestly easier to run than a bare one. ...
