Sera gH Test
Makes it easy to monitor the total hardness
For approx. 420°dGH.
In case of too low GH values we recommend sera mineral salt. High total hardness levels can be lowered by mixing in R/O water.
For creating soft water we recommend adding sera blackwater aquatan or filtering through sera super peat.

The sera PO4-Test quickly and easily provides an overview of current phosphate levels. Excess phosphate is easy to remove with sera phosvec・clear (freshwater) or sera phosvec Granulat (fresh and marine water) or sera pond phosvec (pond).
Sufficient for approx. 60 measurements.

Bala Shark (Silver Shark)
0 out of 5(0)The Bala Shark is also known as the Silver Shark and is a growing favorite among tropical fish hobbyists. They are commonly named silver sharks because of their appearance and the shape of their dorsal fin. These “sharks” require large tanks because of their potential adult size of 13 inches and because this fish does better when kept in groups.

Sera ammonium/ammonia-Test (NH4/NH3)
0 out of 5(0)Makes it easy to monitor the ammonium/ammonia level in fresh and marine water.
Ammonium and ammonia mainly arise from fish waste. They are converted into each other depending on the pH value. While ammonium is mostly harmless, ammonia is toxic to fish.
The sera NH4/NH3-Test allows monitoring the total concentration of both (the actual ammonia level can be calculated according to the pH value the using the included chart).
In case of acute danger, sera toxivec (freshwater) or sera pond toxivec (pond) provide help. sera bio nitrivec (freshwater), sera marin bio reefclear (marine water) or sera pond bio nitrivec (pond) actively counteract lasting enrichment of these substances.
Sufficient for approx. 60 measurements.
