I am looking to purchase a glass lid online or from someone. I live in the US so it is hard to find these replacement lids, any suggestions? I could try to make my own but if anyone wants to sell theirs I would be willing to negotiate! Thanks.
Welcome to the forums! Hate to say it but that might be a tall order. I sell Dennerle and I've never seen their glass tops offered as a stand alone item. If you have a LFS near you, I'd ask them to check with their wholesaler and see if they can source one. Those tanks are packed really well for shipping, but I bet some break here and there. When that happens, the filter and light are typically scavenged out for resale; surely there are tops out there from cracked tanks. But as far as I am aware, there's no way to get just the top even as a special order. Shipping a pane of glass is less than ideal so I'd try to source one locally if you can.
I've seen the glass tops being sold on the dennerle website but they only sell it in Europe... There are some wholesalers that used to sell the tops but they're sold out. I emailed sevenseasupply about their tops as they're a dennerle affiliated company but they said they wont be getting anymore tops.
Yeah I have a friend in germany who may purchase it on their website but no idea how much international shipping would be. Last resort would be to go to my local glass store and request custom-made glass tops with rounded corners. So far, I got a quote for $25 for the glass with rounded corners but the shop doesn't specialize in making the circle in the middle for the finger insert.
You can either 1) skip the hole. 2) or buy a glass cutting hole saw and do it yourself with a drill. If you go the latter I would buy some glass from home depot or wherever and try it a few times on pieces that aren't your custom top.
Or secret option 3) contact Dennerle and ask them if they will ship it to you (which they probably will).
