sera Stream Pump

The SPM 8000 can be safely attached to the aquarium glass with the included suction cup with clamping lever. The ball joint on the suction cup provides the pump with an excellent operating range. sera Stream Pump Manual

sera First Aid Supplies

$16.00 – toxivec 250 ml
$16.00 – Nitrite-minus 250 ml

First Aids

sera Nitrite-minus offers immediate help against nitrite poisoning and prevents new tank syndrome. Accumulating nitrite (“new tank syndrome”) is a threat during the starting phase of a new aquarium, after disease treatment or filter change, since insufficient filter bacteria are present for breaking down toxic nitrite to the plant nutrient nitrate. A nitrite level of 1.0 mg/l is already harmful for the fish.
Dosing: 1 ml per gal of water removes 1.5 mg/l nitrite and converts it into organic amines that are utilized by bacteria. sera Nitrite-minus is very well tolerated by ornamental fish, invertebrates and plants, and can be dosed up to 5-fold.

I keep these band aids handy in my fishroom!

sera Quick Test

$24.00 – 50 Test Strips

Super easy to read and much quicker than drop tests. For day-to-day testing of six critical water values, these lab quality strips are sufficiently accurate to test whether the pH is dropping because the KH is exhausted and a water change is necessary. NO2 and NO3 measurements give instant results in an emergency or reveal the presence of chlorine. Dip in the tank for a second, wait 1 min and read the results. I use these in my fishroom regularly.

sera breeding container

sera Breeding Container

$10.00 – sera breeding container

The sera Breeding Container is 2.5 liters (0.6 gal.) large and thus provides a large swimming space for fry, which is essential for rapid and healthy growth. With a small quantity of sera biofibres it is also very suitable as a spawning container or refugium for injured fish.
