FRT light brack tank is pretty straight-forward. Substrate is a mix of crushed coral sand, tumbled coral trash gravel, and aragonite rice gravel. Filtration is wet/dry with double wide coarse sponges at the overflow (saves a huge mess from the filter). FRTs are a riverine species so, a strong outlet flow won't harm them. Just ensure you provide several current flow breaks to allow the FRT places to rest and sleep. Salinity (here, opinions vary) in my FRT tanks is maintained at 1.007 - 1.010. The species ranges from near full marine to full fresh alkaline conditions. Light brack offers less problems from fungal infections. Temp: ~ 84F. Below 84F they're sluggish and prone to fungal infections. Above 84F makes maintaining a healthy filled-out appearance difficult (less reserve fat layer).
The slough looks like someone peeled after a sunburn. The surface shell layer literally blisters up then, shears away from the carapace in about a day.
Any safe advice to get rid of the algae of that turtle's shell? Would a cloth work? also for brackish, what kind of salt do I use? Never kept anything other than freshwater creatures. How do I calculate salinity?
thanks
