I have been researching for a while and I am gonna get started on a tank for my kids soon just wondered if what I have in my head sounds ok. 45 gallon tank 36" wide was gonna go with an aquaclear 70 hob. Ive read hob and canister is just a matter of preference, but also sometimes in tanks around 50 gallons can have dead spots and require a powerhead to ensure the water is being circulated enough to filter it efficiently unlike canisters that can direct the return water. Is there any truth to this? I was planning on doing a fish in cycle (I already know this is not the most popular, but I have a 3 and a 6 yr old that will be bugging me to have fish in the tank. I was planning on a lightly planted tank, several pieces of java moss on driftwood from the lfs. I was planning on starting with either 5-6 tetras or danios until the tank is cycled. I intend on doing twice weekly pwc's as well as teting 2x daily. I would love to hear any and all suggestions as far as anything I'm missing or you think would help. Thanks in advance.
