Seachem Prime 100 mL
Consider: Small water changes need small measured amounts. Use a graduated measuring tool and the exact bottle instructions; do not estimate tiny doses by eye.
Aquarium water conditioner: compare the choices
1 water conditioner, drawn at its published size on your tank and checked against the maker’s rating.
1 models
No models match these filters.
Clear the search or choose another tank size. The size filter only shows filters and heaters that their maker rates for that size.
The size filter and the fit marks use each maker’s tank-size rating for filters and heaters and the fixture span for lights. Drawings use the makers’ published sizes; positions are approximate. Where a maker doesn’t publish a rating, we don’t guess one; each model page says what is missing.
Before choosing water conditioner
Match the treatment to your replacement water and the exact product label. Bottle size, dose basis and included measuring tools matter. A bottle’s broad claims are not a treatment for sick fish.
Check these against your tank in the equipment planner. Replaced and renamed models.
