The tank is 54 liter ( 15 or so gallons i think) the new (used) is a 128 liter, that i got for for like 5 bucks.
Been looking for a xp 2-3, but the rena filstar products is not avaible in scandinavia
The plan right now is to get a fluval 405, to go with 128 liter... and when that tank is gonna be replaced, get a "aquael canister filter with UV ligth" and run it together with the fluval
Next tank is gonna be a 325 liter.
Think the picture is messing with you, the flat rock is fully exposed to the light.
yeah its a uvb bulb (euro zoo)
edit : Basking themp is at 33 - 35 celcius, water temp 25
