my reason for wanting it is its got 10 ml capacity and it can run at higher wattages then the subtanks. i've had the arctic tank the starre tank and the subtank plus but my arctic starting leaking a lot, my subtank plus has capacity but not the higher wattages and my starre tank replacement glass broke and after i replaced the glass for the starre it started leaking for some reason and the tank was on tight but its more of me wanting something with more capacity that could run at 50w or higher
