Sand! SOS

It looks to me like your vortech is pretty high up and it still blasts the sand? So maybe just try a heavier grain of sand?

Yes Kien, if I keep my vortechs at its 50% I won't have any trouble however I feel like there's no enough flow!! LOL (maybe it's just me )

I test my tank's flow with my hand and like I said, it seems like there's no enough flow.. but this may be inaccurate

So I don't know what to do.. I want lots of flow for my SPS
