Setting up from scratch?
Answer three questions and we'll build the basket for you — essentials, system, and what to skip.
Starting a new tank
More fish are lost in the first month than in all the months after — almost always to ammonia in a filter that has not matured yet.
See the fixCloudy water
Cloudiness is almost always one of three things: a bacterial bloom in a young filter, disturbed substrate dust, or overfeeding feeding the bloom.
See the fixAlgae
Algae is not dirt — it is a sign something is out of balance: usually light hours, feeding, or nutrients the test kit will name.
See the fixFilter maintenance
Filters fail quietly — flow drops, media clogs, and water quality drifts weeks before anything looks wrong from outside.
See the fixPlants not growing
Yellow new leaves, pinholes in old ones, stunted tips — each points at a different shortage, and dosing blindly fixes none of them.
See the fixShrimp keeping
The difference between a colony that breeds and one that fades is usually parameters, not food — shrimp read water more closely than any fish.
See the fixSick fish need eyes on the animal and test numbers, not a bottle shipped blind — we don't sell medications this way. Ask in the community or message us and we'll point you at the right test first.
