converting 135 glass to 100 gallon acrylic...need plumbing help...calling all experts

[Mbeef61]

im moving into an apartment and im converting my 135 glass sps reef to a 100 gallon acrylic. right now the 135 (72x18x24) uses 2 hang on the back overflows...and a mag 12 for sump to tank flow.
the tank im getting is 100 gallon acrylic (60x18x20.5). im not that familiar with drilling tanks but i know the basic concepts. what i want to know is where to drill the holes for the overflows and how many...and what size? i would prefer to use the mag 12 or some external comparable for sump to tank movement. also, i want to incorporate a closed loop...maybe with a sequence dart? does that sound about right? where should i drill this plumbing?
any help or suggestions would be great. also diagrams are aweome...thanks in advance.

oh also ...the sump is a 33 gallon aga (48x12x13)?

Upscales and Waves can drill tanks and surely can help you work thru your questions.

Drilling acrylic is easy! Take it slow and use a decent hole saw.

[nu2reef-n]

Back up your drill or hole saw with a piece of wood.
You don't want to crack the tank.
Don't forget.......go slow.

Here is a pic of the diagram I used for my 8 foot 240 gallon tank.

Drilling bulkheads are easy.

Let me know if you have any questions. This was my first time drilling acrylic. I didn't have any problems. Just go slow. Clean your hole saw as it gets clogged with acrylic shavings. Drill halfway through, and switch sides. This will reduce the possibility of a crack when completing the cut/hole. If I can do it, anybody can.

Buy a sheet or two of acrylic at home depot to practice on...

thanks for the help so far...another question/concern i have is with the design of the overflow inside the tank...i think i wanna drill the overflows towards the top...what do you all use to cover those? i know some people just use a screen over them...but i would more like some sort of prefilter box like the ones i have for my glass tank now...even better would be some sort of adjustable one to fluctuate water lines...any suggestions?

I don't think you will need adjustable ones. You could make a overflow box or just use those screw in screens. Its up to you. Both would work fine.

One nice thing about internal overflow boxes is they allow you to use Durso-style standpipes to help cut the noise.

I have internal screens on my overflows.

What I really wanted was a coast to coast overflow. The internal screens are kind of a bother. I have had to clean them about every week, but that was due to a hair algea problem. The hair algea is almost gone, so we will see how long it is between cleanings now. Coraline will also plug the holes in the screens, but a vinegar bath with fix that.

Yah coast to coast overflows are nice.

[Mbeef61]

not familar with what that is but from what i take it from the name its an over flow that goes all the way across the tank? any pics or links to this style? i like how the durso style standpipe usually never fail...but i hate how it takes up aquascaping space...as for the screens that was my first thought when thinking of ideas...the complaint i have heard most is they clog...however i dont have anything to clog it up...i almost wish i could have some hair algae to feed the tang! lol just kidding...coraline however i do think could have an affect...but like you said VINEGAR!

do you have any links to those coast to coast style?
wheres best to get those screens if i go that way? LFS or online?

also....would 2-1.5'' intakes t-ed into a 2 inch pipe be better for the sequence dart than just 1-2'' intake? to kind of spread the suction out
? also...for those with darts? whats best for returns on a 60'' tank? 3 or 4? im thinkin maybe 2 sea swirls if i can afford.

Portland stores Waves, and Upscales I believe

Salem store Advanced Aquarium

Eugene store Liquid Sunshine

2 intakes - more room for error

I would think 4. I don't know how much sea swirls are but you might look into an Oceans Motions 4-way.
