Many thanks to all of you for helping me to get a comfort factor with ordering from this vendor!!! I'll likely place my order with Jehmco, tomorrow. I did check out some of the other etailers, however, Jehmco seems to have the most complete inventory for the ATI hydro sponges and are the only ones from who I could find the pond pre-filter I want (the HS-PIV).
As a bonus, they also have great prices on NLS pellets (which I intend to try). I've been a Hikari fan for the last +10 years, however, Hikari (food sticks) break apart and just create a dust storm in my tanks. My fish seems to love it though. I bought a small jar of NLS from my LFS over the weekend. My fish just swallow that up whole and no food "dust storm"!!! A promise I must explore. And, it is much less expensive than the Hikari!!!
