jim r Posted September 4, 2008 Report Share Posted September 4, 2008 It is totally safe, looks pretty good and does not take much cleaning. Quote Link to comment Share on other sites More sharing options...
new zealand discus man Posted September 5, 2008 Report Share Posted September 5, 2008 Hi All my 124 tanks are u/g filters and Waikato River Sand..45mm thick There is a nylon pad on filters to keep from going through.. 5mm thick Warning.........The PH can drop ----> below 4 ----> Yes 4 PH :evil: To off set...Cockle shell is at Stevensons Depots...Cheep...A good hand fill is enough for 300 L tank ...I use 100% rain and only mains with africians..Tangs Dick Smith have digital PH meter for around 70 dollars..Colour PH testers cannot be trusted...My Views...Also Sand / Shell must be washed in say wheel borrow till runs clean water..Then...Dry out completely on concrete drive or simular..Water bugs cannot live when dry for a couple of days in good hot weather..Or chlorinate for 6 hours..Very strong chlorine.. Sands advantages.....Baby fish cannot get lost in caves and food / droppings can just be netted off... Hope helps.....Cheers Phill Quote Link to comment Share on other sites More sharing options...
