So on my 30 gallon convict tank (just 1) that has sand substrate the convict gets amused by spitting sand in the intake tube which burnt my motor up (funny jerk fish), so I bought another 50 and a pre filter so sand won't get sucked into the motor again (luckily I have 2 filters on the tank), what I'm curious about is the media, should i use the old media from the one that's in it right now plus the new to get it established I'm assuming the answer is yes as that's all my BB, also is a pre-filter a good thing to have as I have 2 on my other tank a 110 and a 70 and thinking about getting pre filters for those not sand substrate in that tank though. .
What do you all think about the air driven powerheads for them?
