4 x 2 x 2 tank

[simmonsim]

Finally got a tank drawing design by myself. Hope to get some advise from all bros & gurus here. As mentioned on the topic, I am planning to do a 422 tank with 12mm (so called the starphire glass).

Am a newbie in this hobby, hope to get some more advise.

My current idea is, already have a 5 feet stainless steel rack & this 4 feet is to be put on top of it with overflow box (8mm glass) attached on the side. (Divider type tank)

My concern is :

01) Do I have to put TOP & BOTTOM bracing ? For TOP bracing, how should I do it ? Heard there are so many designs.

02) How high is the TOP bracing ? Any recommendation on the measurement ?

03) What is the best measurement for overflow box ?

My plan is A : 3 inches, B : 6 inches, C : 6 inches, D : 10 inches & E : 12 inches

04) Do I need only one hole for water flow down to sump tank ? What is the diameter recommended ?

05) For the overflow box, what type of gadget or piping do I need to do to get water down to overflow as silent as possible & design to avoid overflooded ?

That's all my question at the moment. And, sorry for my poor english.

Thanks

your bracing question can be answered by your tank maker. Take for example, if you go coral reef to make your tank, they can do it braceless and give you warrant. for your overflow box, it is the same. it will depend on your supply and return pipe size. good to have 2 supplies and returns. for supply can go for 25 and return 32. the bigger.they are, yyou have.more choice for return pump. for silence operation, incorporate durso pipe and also ensure yr return pipe to the dump has valve to control. hope this help.
