• Alkaline Water
• Hard Water,contains dissolved Mg and Ca, general Ph of 8-8.5
• Can be caused by concrete bricks, concrete, excess lime from runoff or calcium sources from shells
• Can be caused from a hard water supply
• If you have white lines on the water line, this indicates mineralization, and most likely, Alkaline water
• Promotes algae Growth
• Sunlight causes Plants to absorb CO2, increasing the alkalinity of the water
• Ammonia is Alkaline
• Nitrite is slightly alkaline (depends on Nitrite, but generally is alkaline)
• Nitrate is slightly alkaline (depends on Nitrate, but generally is alkaline)
• Caused by Decaying material and fish sludge
• Acidic Water
• Rain water, contains dissolved CO2 general Ph of 6-6.5
• Soft Water, slimy feeling when you wash off soap
• Adsence of sunlight causes plants to stop absorbing CO2, increasing the acidity of the water
• Chlorine in Water
• Fish turn upside down when you add new water
• Fish start "peeing" white strings that dissolve
• Fish turn pale
• Fish appear to be struggling for breath, or struggling to swim
• Brown Gills
• Fish start to dart around
