Expanding on Parameter Deep Dive
Delving deeper into the table, ammonia (NH3) forms via bacterial decomposition of uneaten food and excretions. In new tanks, the “cycle” phase can see spikes of up to 5 ppm—fatal without intervention. Your aquarium water test kit tracks this, guiding beneficial bacteria additions, such as Seachem Stability.
Nitrite (NO2-) follows, oxidizing via Nitrospira bacteria. Symptoms include “brown blood disease” in fish, characterized by rapid breathing and fin clamping. Ideal zero levels prevent this, achievable with 20% weekly changes.
Nitrate (NO3-) accumulates slowly but fosters eutrophication, which can lead to oxygen-depleting algae. Below 20 ppm supports invertabrates; over 50 ppm invites ich outbreaks. Fast-growing plants like hornwort naturally halve their levels.
pH, the acidity scale, fluctuates with CO2 injections in planted tanks. A drop below 6.0 dissolves calcium shells in snails. Buffers like Seachem Malawi add stability, confirmed by tests.
Hardness metrics—general (GH) for minerals, carbonate (KH) for buffering—prevent “old tank syndrome.” Low GH (<4 dGH) yields soft water for blackwater setups; high suits African cichlids.
Mastering these skills through consistent use of an aquarium water test kit elevates your hobby from casual to expert.
