You do not need the biggest unit on the shelf. You need the one matched to your actual water volume and stocking. The aquarium net is one of those purchases where the right size matters more than the brand name.
What it does
It performs a single, unglamorous job that keeps the tank stable — and stability is what your fish actually feel.
How to choose
Size to the tank, not the shelf. For a typical 68-gallon setup you want a net sized to your fish; a unit rated for 820 L/h of flow (around 15 W) covers most stocking levels without over-driving the water. Check our epistylis in a planted tank guide for the bigger picture before you commit.
Setup tips
- Position it for even flow or heat distribution — dead spots are where problems start.
- Prime or rinse media in tank water, never tap water, to protect beneficial bacteria.
- Build a spare into the budget; when it fails at 2 a.m. you will want the backup.
Maintenance
Clean on a schedule tied to your water change — every 6 weeks is typical. Rinse reusable media in old tank water and replace only what is truly spent. Pair it with the platy care: easy, colourful livebearers so the whole system stays balanced.
Keeping it running
Service the aquarium net every 2 weeks alongside a water change: rinse reusable parts in old tank water, replace only what is spent, and keep a spare on the shelf so a failure never becomes an emergency.
