Check flow and intake protection
After maintenance, confirm that water is moving through the filter and that hoses, sponge, or impeller are seated correctly. Make sure tiny shrimp cannot enter an exposed intake.
An unusual reduction in flow may point to assembly or clogging issues. Follow the manufacturer’s instructions rather than forcing a part into place.
Preserve the biological surface
Avoid replacing or sterilizing all filter media at once. Beneficial microorganisms live on media and other surfaces, so aggressive cleaning can disrupt the system.
Use the filter maker’s maintenance directions and suitable water for rinsing. Do not assume that a newly cleaned filter is biologically mature.
Monitor water after maintenance
If the tank was disturbed, check ammonia and nitrite according to your normal practice. Keep feeding modest while the filter settles.
Record what media was cleaned and when. If shrimp become distressed, review the maintenance steps and measurements before adding treatments.
