    Is there any other sealer that can be used to put the baffles and glass inserts in a sump.I didnt know if there is anything cheaper than the aquarium sealer

    Yeah, GE Silicone 1. Silicone 2 has anti mold mold chemicals that can be harmful to fish.

    Acrylic or Glass?

    Glass, you can only use silicone (as far as I know). GE 1 as suggested.

    Acrylic you can use acrylic glue - not entirely sure which one's are considered tank safe though (I've never researched as I only use glass).

    If the baffles are acrylic you can use Lexon silicone I got mine at Lowes.
  7. mountaindewNew MemberMember

    I am going to use glass.I heard lowes have glass pretty cheap
  8. JessiNoel21Well Known MemberMember

    Yes they do I got mine for $10 total for 8 pieces they will even cut it if you have the exact measurements.

    Thank you.What thickness did you get.I talked to lowes and he told me the only sheets of glass that they carry is picture frame glass which is not to thick

    What volume of water?
    I think most 20G tanks are a minimum 6mm or 1/4" thick.
    The more water, the thicker the glass needs to be.
  11. mountaindewNew MemberMember

    Im not sure what thickness picture frame glass is
  12. ryanrModeratorModerator Member

    Picture frame glass would be pretty thin I would imagine.

    Oh, and I would think most aquarium glass would be tempered, at least for the base panel.

    1/4" thick,where is a good place to get that so its not so expensive
  15. JessiNoel21Well Known MemberMember

    I got mine at Lowes but you can try Home Depot or a glass supply store.

    Oooh, I just remembered one aspect of glass thickness. It's not the volume, or the length that determines the thickness required. It's the height!

    I just recalled building my tank, and the builder said with the height, I should go up a size.

    Here's a pretty cool calculator (in metric, 1" = 2.54cm)  

    With my dimensions, it recommends 9mm glass, I went for 10mm (12mm base). Whilst the length does have an impact, it's nowhere near the height impact.

    Dropping 6" in height reduces the thickness by 3mm, whereas a foot in length equates to 1mm

    I got the glas at lowes.Thanks.I have piece of acylic that needs to be cut.Can I use a dremel to cut acylic

    so is it tempered or not? I have quite a few tanks that have cheap none tempered panes in them, I like to scrounge for tanks. haha. broken or leaking means free to me
  19. mountaindewNew MemberMember

    Im not sure.I got it from the local hardware store.I need to cut a 4in circle in it.Just trying to figure out what to use

    You need to get yourself a diamond tip hole saw, and go very slowly. There's lots of videos on youtube about drilling a tank. But if the glass is tempered, my advise is not to drill it. Tempered glass shatters easily.
