I agree they are hard to find .........I had to drive 350 miles for my last three that I lost this week they where 6+ in my 300 gal tall tank.
I have a water station that goes to both my salt and fresh water systems and I did a water change on my freshwater tank and left the valve open at the water station.... and after having my water station for over a year with no problems, yup it was time for water change in my saltwater system and did not notes the valve open........it was already lights out on the tank and everything in my fresh water tank was dead....... years of fish gone in one night..
Any way I cant blame anyone but me........
Like others at this point you start thinking it is time to start over or end the hobby. almost decided to sell the system till I went to a local fish store this weekend that I havent been in a while and they had two big GATF and I was hooked again ,,not selling anything starting over ..... So I am hoping to start out with two large GAFT.. The fish store would not sell them ...
