How much is he charging for the tank? that same place has the brand new 5# tanks for 55 bucks made by linwood. Its worth it and by me its 15 bucks to fill the tank.
T5E tank- $59.99
sms122 ph controller-$115.99
thats the prices brand new for the 5# rig I got from them. If it has to be retested already its alteast 5 years old.
