Ph: thats what I was thinking. I know that the better blocks need a pretty large pump to work well. going back to the regret-i-paid-too-much thing, for the price I did pay, I couldve gotten a WW and a >300 GPH pump. Oh well. I like this so far, its good as I'm learning what the hell to do
/edit: yes thats a battery in the T-line. Its all I could find that'd fit. Its wrapped in tape to prevent corrosion
