AQUARIUM DECORATIVE ROCKSWe supply natural and artificial rocks as retail and wholesale.More than 50 varieties ofRocksPebblesStonesSandsStone-chipsPumicePolypHeavy-bolderPeatBog-woodCurio-woodTerracotta’s cave and models etc.RocksThere are a lot of rocks to avoid in the fresh water aquarium, these include - Ores (rocks containing metal) & Calcareous (rocks containing Calcium) these shouldn 't generally be used for fresh water tanks. As a rule of thumb, test the rock with an acid to see if it fizzes. If it does then the rock contains calcium and is unsuitable for aquarium use. I use white vinegar but you can, with the proper precautions and safety gear, use hydrochloric acid. Also you should pour boiling water over your rocks or wherever possible immerse them in boiling water to clean them and to kill any unwanted bacteria that may be living on it. Do not boil or roast in an oven and never use a microwave to heat up rocks.Note; Rocks retain heat for a long, long time be extremely careful when handling hot rocks.AlabasterSee GypsumAmethystAmethyst is a form of quartz, however it also contains Manganese and Iron.(this is what gives it the pale lilac to deep purple colours) darker the colour the more iron contained in it. The darker the piece the more hazardous it could be in an aquariumDead Coral. For Marine tanks only! Not Recommended.Due to the poor collection methods and the unnecessary reef destruction this is a morally poor tank decoration and prohibited in some countries. Realistic artificial pieces are now widely available and are a much better choice.Flint. (Flintstone)Flint is usually dark grey, blue, black, or deep brown in colour & can be very sharp. It will scratch your tank if not positioned carefully.Geodes. Not Recommended.Geodes primarily consist of limestone, however many are quartz based. Sometimes minerals contained with in the hollow are harmful & even those that are ï¿½safeï¿½ are often razor sharp and can be lethal to fish.
