I'm refurbishing a tank that I have had running for about 6 years. Everyone finally died, so I'm taking out the coral substrate, and starting anew with sand.
I notice by reading several boards that there is no more undersubstrate type of filtration being used...I was running a powerhead sucking from underneath and a whisperclear 200 hanging on the back...
My question is...what am I to use now....my tank is a 20 long...i plan to do FOWLR. I'm pretty sure that little whisperclear isn't enough of a filter for my tank...any suggestions?
