[i have crabs]

nope not me, i kinda doubt the noise is abnormal, it just seems like thats how it is,
anyway,i hooked up the extra phosban reactor i had with a mix of carbon and gfo from bulkreefsupply, sunday i had a big explosion of diatoms so i cut down th lights to 2 bulbs for a while, the vortec has ben running at about 1/2 speed for now so i turned it up and all the sand from the front of the tank is ending up at the back of the tank now so i hope this will not be so bad when i have more rocks in thier cause a 2" bare bottom strip at the front will really pee me off, im gonna try and go get some acrylic rod for the rockwork in the next week and hopefully a can afford a few hundred bucks worth of rock so i do some work on that
