Thanks everyone for jumping in with this flurry of answers. It was a sharkbait feeding frenzy! (OK,I hear the groans!
) Also, thanks to the admins for deleting the extra posts. I really should know better.
I read through the post that Menagerie was kind enough to point out. There is some great information there too.
I may end up choosing a cannister setup, because it seems so simple. However, right now I find the idea of the overflow/sump system fascinating. The idea of combining a sump and a cannister is brilliant. I assume since the cannister has a pump built in that you just stick the input into the sump. That might even help with the noise mentioned by Shawmutt.
It must be the DIY
'er in me that all this appeals to. Did I mention that I'll be designing and building my own stand?
OK, some more questions since you have all been so helpful.
What types of cannisters are capable of polishing the water? I have read some about Magnums and their micro filter w/ diatom powders.
Would it be possible to use more than one cannister? For example, use one cannister as needed for polishing and another full-time for the chemical and mechanical filtration.
When using more than one cannister, would you run them in series or parallel?
If I choose to do some sort of a sump with a wet/dry trickle filter, are Bio Balls the way to go? Has anyone tried cut up clear drinking straws?
Are there commercially available overflow boxes? Is it better to DIY
Would you recommend a commercial sump or a DIY
? Why? I'd love to hear some of the issues.
Is there a guideline for determining the sump size?
