I'm in the planning stage of making a small sump for my 20g display, probably around a 12 - 15g sump. I had first thought about acrylic, but getting it shipped makes the cost of even cheap material double. I then thought about using a glass aquarium and installing baffles, but I haven't a clue as to where I could get glass cut.

So my question to those of you with tons more time in the hobby than myself (and hopefully experience with DIY) is there anywhere in DE I can get my hands on acrylic or a place where I can buy and have glass cut?

just about any glass shop in the phone book will have acrylic in stock along with Home Depot and Lowes. and glass shops will cut glass to any size you need.

what part of De do you live in? if your up north i can give you the names of some good glass shops

better yet....do what Mr DIY GreenEyedBlackCat suggested to me and by a glass tank and use acrylic baffles. you can get a sheet of 1/4" acrylic at homedepot for $12 and cut it with a dremel. use a $3 tube of silicone to adhere the acrylic to the glass. here is one i helped my friend build. everything together was less than $50 including the 20gal tank and diamond bit to drill through the glass for return and sensors. the one Jim helped me build works like a champ.

Cutting sheet glass yourself isn't too hard: you need a cutter (cheap), a good ruler, a steady and strong hand, and patience. Measure carefully, set your steel ruler in place, draw one unbroken, unhesitating line down the desired cut, place the scored line over the edge of any table/counter, and tap gently down the cut, holding your hand ready to receive the cut piece as it drops off. If you've drawn a strong, sure groove, it will part exactly there. You do not near need to go any depth into the glass. This works on plain, untempered glass. You'll want several scrap 'practice' pieces until you learn the right pressure and stroke.

Sk8r, I may need to go through quite a few practice sheets, but that's a definite option.

Logans_daddy, what kind of silicone do you use for an acrylic to glass bond?

logans_daddy

any silicone will work(except for bathroom/kitchen) and they do make "aquarium safe" silicone. i get it free from work. i used GE windows/doors on the first sump.

I made my fuge from a ten gallon tank and glass that i got cut at sears for real cheap. And you can get many designs on the web and find the one that you want. Also doing the silicone is real easy, just make sure that you have something to rest the glass on to keep it in place while you are working. goodluck

Logans_daddy, I appreciate the input, but I have one last question. Where in Home Depot can I find the acrylic, and does the acrylic go by a specific name?

Cmondo, you got glass cut at Sears? Where?

the acrylic from HD can be found in the lumber department, plexiglass is acrylic. just remember that silicone doesnt adhere to well to acrylic so if you have any water pressure the seal will break

i dont know mmbuna...once it sets its on there pretty good. i can grab one of my baffles and lift the entire fuge by it. but i also used a LOT of silicone. also....there isnt much pressure on the baffles at all. here is a great site with plenty of example fuges.

btw....im not sure if the north wilmington HD is layed out like the one in new castle, but the acrylic is on the end of the windows and doors isle with the lexan.

no...i definitely believe you.....but as you can see from my pic....my philoshpy when it comes to silicone that you will never see... MORE IS BETTER.

I think cmondo and I both get our glass from sears hardware in the college square shopping center in Newark
'
they have cheap glass and cheap cuts - maybe $.50 a cut - although they've cut it for me plenty of times for free (just charged me for the pane of glass that I bought) total cost for a pane of double-layer glass was like $10 - if you can find some pieces in their scrap heap, it will be even cheaper ;)

Thanks Nick, yeah that is where I got my glass, but i think i got lucky cuz all of my glass totalled up to 3 bucks for all the baffles.

lol - yeah, last time I was there, my bill was 50 cents since it was scrap and I only wanted one cut, but I wouldn't want to quote that price to anyone and have them be dissappointed :)

Sears cuts glass? I had no idea. I'd imagine this would be done in the hardware section, correct?

the sears that we're referring to is just a hardware store (sign reads "Sears Hardware") - I don't think other Sears' would do the same.

It is located in the College Square shopping center - Take I-95 to 273 towards newark, the shopping center is at the intersection of 273 and 72 (kirkwood HWY).

You guys have been amazing. I appreciate it.

Ok, this is my last question in regards to this issue. When I go to this Sears, what kind of glass should I ask for and what kind of sealant should I purchase?

plate glass is fine, and window and door silicone. dont use kitchen and bath silicone, it has fungicides in it

Great! Once I have my sump up and running, I plan on adding corals not soon after and hopefully I can be a contributing member to the DRC.

welcome to the DRC coogarts! PM me with your email if you want to be on our mailing list.
Thanks for the sump link Shawn, I see some designs for a 29g... think I have a new project on my hands! Luckily I have lots of empty 10g tanks around as a base structure...

it is very easy to cut the glass panes that HD or Lowes sells they are really thin, I was able to even cut some 1/4" glass with the scoring tool they sell. The tool is like 8 or 9 bucks. You score it once and snap off the end. Be extremely careful with the cut pieces as they are razor sharp. I went with glass on glass because my friend said his acyrlic to glass didnt hold over time.

Try to place the cut end facing down in your sump/fuge so you dont come in contact with the sharp end when your doing maintenance on your sump/fuge.

Yeah you wouldn't want to kill your mushroom corals now would ya :D Sorry couldnt resist!

Nice thread and great info!

Bah, my questions seem to never end. Sorry. I was talking to my father about my latest project (even though I'm out of the house, he still likes to help my with projects) and he questioned whether glass that isn't tempered can be bonded to tempered glass.

Is this a real worry?

On the plus side, I just received my mag 5 and aquarium that'll be the sump.

Tbor, PM sent.

silicone will bond tempered to plate

kaptken

thats right, you are not welding tempered to regular plate glass. silicon is a caulking bonding to both. or at least adherring to each. even so its not a strong connection. its flexible and can be peeled off with pressure. its not at all like an acrylic bond where you melt both pieces together with solvent and form an actual molecular weld. silicon is just surface adhesion. very weak. more of a sealant, like in the aquarium. the frame holds the plates close together while the silicon seals the gap . silicon is not a structural adhesive.
