Hi guys and gals:

New kid on the block--thanks for all the information and insight. Might someone be so kind and point me in the right direction for information/theory on the various options of running two canister filters and the best ways to plumb them via bulkheads in the bottom of a tank of around 100 gal. I have been making my way throught the massive amounts of information in the forums and I've learned a tremendous amount...thanks for the help, but I've not really been too successfull searching for this topic. Specifically, Im interested in the concept of four bulkheads drilled for two filters....or 2 bulkheads drilled for two filters. Four seems like a better idea to me and would help to eliminate various pressure issues &c and allow each filter to be as effecient as possible. However, I would very much like to understand these concepts better before attempting it. Your insight would be greatly appreciated.

Best Regards,
Justin Szkalak

Hi,

Drilling the bottom of the tank for input and outlet bulkhead fittings is a great thing.

Basically you simply hook the INPUT of the canister to an input bulkhead. The canister outlet can go to the outlet bulkhead...

Up to you on whether a pair of bulkheads per canister or if you want to merge them.

You will get better performance with separate bulkheads for each canister. Gives you more options in the future.

Look for threads by myself, Jdowns, Tom, and others that have drilled tanks...and closed loop plumbing..

Here is one that has some good info albeit a bit long..(mostly my fault)

Hope this helps.

Got Holes?

Hi,

Drilling is good, http://www.glass-holes.com/Glass-Hole-Cutters_c7.htm, is where I get my glass hole-saws. :)

Four holes are definitely better than two.

Take your time follow the directions; go for one hole-size larger than you think you need. Make the edge of your hole at least one hole diameter from the edge.

When drilling tank bottoms make sure it is not tempered glass, when tempered glass is used it is usually (always?) on the bottom, generally it is marked.

Do not over-tighten bulkheads; do not use silicon unless you know the seals (gaskets) are compatible with silicon. :gw

Have fun and do what Gerry says. :cool:
