I'm replacing the old plastic top on my 20g tank(most of the top is solid, non-transparent plastic which is a no-no for plants). Does anyone have a direction to point me? I'm speaking mainly of some nice glass tops I saw somewhere, I just can't remember where.
Thank you.

All the big glass-tank manufacterers make glass tops to go with them. Check all-glass.com or oceanicsystems.com to find out the nearest dealer.

Petco has some decent glass tops I noticed the other day. I need to get one for my 75, and three for my 20Ls sometime soon.

I go to a local hardware store for glass cut outs to my specifications. I believe it cost me $4 for a 20g. Petco wants over $20.

I agree with Rolo. My local hardware store is much more affordable. However, my hardware store doesn't grind and polish the edges. I haven't tried it, but I would think some fine sandpaper would do the trick. Just be careful - I would wear a breather mask, safety glasses, and gloves. The glass dust could potentially be dangerous.

Hi,
The 1/8" thick glass works fine for most tanks. Use 300/0 jewel garnet sandpaper to smooth the edges (using LaCrosse gloves and a Mark V gas mask:) and will cost less than 1/4 what a commercial glass top will run. If
you want it hinged, measure closely, keeping in mind if you are using a HOB powerfilter and have them cut 2 pieces and use aquarium-safe silicone cement: run a bead down the seam of both pieces then smooth out with a
freshly peeled potato with a flat side cut into it. The silicone won't adhere to
the potato and does a nice job of flattening out the bead. YMMV, always, :smile:

That sounds like a neat trick....so silicone wont stick to a potato...how in the world did you figure that out! :)

Kevin, an oldtimer I met in Portland Oregon back in 1981 taught me that. I
had an old 40 gallon Metaframe I was repairing. It's the starch in the potato
that does the trick.

To polish the edges you might want to use a wed/dry sandpaper on a rubber sanding block. First, wet the sandpaper and glass, then after you're done sanding you can wipe up the residual water/particles with a paper towel. Just keep eveything wet by dipping the sandpaper into a bucket of water often.

One other thing you can use (if you have one) is a wet stone for sharpening knives. Same principle as the sandpaper, without needing a sanding block.
