Notes on Planted Tanks

This is a small site about aquariums. Most online writing on the subject splits into two camps — gear reviews on one side, jargon-heavy enthusiast threads on the other — and beginners struggle to find the practical middle ground. The aim here is the opposite: notes that came out of years of cycling the boring parts of aquariums.

If you are completely new, start with cycling a tank — that is the foundation that makes the rest easier to learn. Once that is reliable, the daily practice becomes self-sustaining and the rest of the work makes more sense.

Cycling a Tank

The most common question newcomers ask about cycling a tank is some version of "am I doing this right?" The honest answer is usually "close enough, keep going." Cycling a Tank is not a binary skill. There are better and worse approaches, and there are catastrophic mistakes you should avoid, but inside that range any reasonable method that you stick with consistently will improve your aquariums steadily.

If you want concrete reassurance: work on cycling a tank for a month, then look at your results from week one alongside week four. The improvement is almost always visible. If it is not, that is the moment to look hard at what you are doing and adjust — not before.

Water Parameters

One of the under-discussed truths about water parameters is that the best practitioners often do less of it, not more. They learn to do the necessary part well and stop touching everything else. Beginners almost always over-handle water parameters — adjusting things that did not need adjusting, fussing with details that did not need attention, second-guessing decisions that were already correct.

If you find yourself fiddling with water parameters during a session, that is usually the moment to step back. Make one deliberate decision, commit to it, and see what happens. The discipline of leaving things alone is a real skill in aquariums and pays dividends across the whole practice.

Feeding

One of the under-discussed truths about feeding is that the best practitioners often do less of it, not more. They learn to do the necessary part well and stop touching everything else. Beginners almost always over-handle feeding — adjusting things that did not need adjusting, fussing with details that did not need attention, second-guessing decisions that were already correct.

Choosing Fish

Choosing Fish rewards small, frequent attention more than periodic deep dives. A few minutes spent on choosing fish every day or two will, over a season, beat a single long weekend of intensive work. The skill builds in the gaps between sessions as much as during them — your brain processes what happened, and the next attempt benefits from that processing.

This is good news for busy adults. You do not need long blocks of free time to get better at choosing fish. You need consistent short blocks. Ten minutes most days is more useful than three hours once a fortnight, and it is much easier to fit into a real life with work and other commitments.

That is the short version. Aquariums rewards patience more than cleverness, and almost all of the visible improvement in the first year comes from showing up regularly rather than from any single decision about gear, method, or planted tanks. Most of what is on this site assumes the same thing: that you intend to keep at it, and that you would rather be quietly competent in two years than dramatically excited for two months.
