Knowing your true aquarium volume helps you stock safely, size equipment accurately, and dose medications correctly. This guide teaches beginner-friendly methods to calculate litres and gallons for common shapes, account for glass thickness, freeboard, and decorations, and avoid mistakes that skew measurements and compromise tank health for safer, steadier results.

Clear water is not always safe: unseen toxins and imbalances quietly threaten fish and plants. Regular testing reveals problems early, supports the nitrogen cycle, and protects beneficial bacteria. This beginner guide covers what to test, how often, and practical steps to keep tanks stable, healthy, and stress-free for lasting success.

Healthy water starts with a thoughtful change routine. There is no one-size-fits-all schedule; tank size, species, plants, filter, and feeding all influence how often you change water. This guide helps you tailor a steady routine, test results guided, that keeps nitrates low, pH stable, and fish thriving for years ahead.

Feeding your aquarium is about consistency. A simple routine—tiny meals once or twice daily, finished in 30–90 seconds—keeps water cleaner and fish healthier. Include a weekly fasting day, match feed times to lights, and tailor portions to each fish type. With observation and simplicity, your tank thrives, bringing color vibrance.

Clear water supports healthy fish and thriving plants. This guide explains GH (general hardness) and KH (carbonate hardness), how they affect pH stability, and why both matter. Learn simple testing methods, interpretation, and safe adjustments using buffers, RO water, or boosters, with slow, consistent changes for species-specific needs and goals.

Choosing aquarium water matters most for fish, plants, and budgets. Tap water is safe when treated for chlorine and chloramine, predictable and quick. Rainwater is soft and potentially contaminated, requiring filtration and remineralization. Mixing waters offers balance. Test regularly, keep KH and GH stable, and change gradually for health outcomes.

Nitrates are a common aquarium challenge. While not as immediately dangerous as ammonia, high nitrate stresses fish, fuels algae, and dulls the tank. This guide explains what nitrate is, why it rises, and beginner-friendly methods to lower and stabilize it through testing, controlled water changes, plants, macroalgae, and feeding habits.

Black beard algae can ruin an aquascape, but it’s solvable. With a clear plan, simple tools, and a few habit changes, you can remove BBA and prevent its return. This guide explains causes, step-by-step removal, and long-term tips to keep your aquarium healthy. Start today for clearer water and growth.

Cloudy aquarium water can worry new fish keepers, but most haziness has simple causes and safe fixes. This guide helps you identify the cloud’s color and source, then shows quick, step-by-step methods to clear it and keep water crystal clear. Learn testing, filtration upgrades, water changes, and preventive habits too.

Cyanobacteria blooms frustrate aquarists, smothering plants, stalling filtration, and souring tank smell. This guide offers a beginner-friendly plan to address both slime and root causes: diagnose sources, remove blooms safely, and rebuild balance with nutrients, flow, light control, and regular maintenance, so algae stay in check and tanks stay healthy.
