Using hornwort as a filter medium
By accident this has turned out to be a big problem solver for us,we had left a tank containing about 700 gallon to its own devices, because it was near an area we were...
Category: About water quality
Water quality is the most important factor affecting fish health and performance in aquaculture production systems. Good water quality refers to what the fish wants and not what we think the fish wants. This means that we must understand the water quality requirements of the fish under culture very well. Fish live and are totally dependent on the water they live in for all their needs.
Different fish species have different and specific range of water quality aspects (temperature, pH, oxygen concentration, salinity, hardness, etc.) within which they can survive, grow and reproduce.
Within these tolerance limits, each species has its own optimum range, that is, the range within which it performs best. It is therefore very important for fish producers to ensure that the physical and chemical conditions of the water remain, as much as possible, within the optimum range of the fish under culture all the time. Outside these optimum ranges, fish will exhibit poor growth, erratic behaviour, and disease symptoms or parasite infestations. Under extreme cases, or where the poor conditions remain for prolonged periods of time, fish mortality may occur. Pond water contains two major groups of substances.

About water changes
Water changes replace minerals, which help to ‘buffer’ the water and maintain stable conditions, and reduce Nitrates (NO3) that may gradually build up over time, causing long-term damage to your fish No matter which...
Evaluating the pH of your water for the aquarium
When considering a new aquarium the hardness and pH of your tap water is the first thing you should evaluate, once you know the characteristics of your water supply it will enable you to...
