Glass top and metal screen for Rimless tank

[Basile]

Thanks guys for all your posts, i get most of what you're saying i also know about some of the facts you've put foreward. I'm aware of the oxygen restriction i would impose on the system, the light diffusion by the glass and salt. I've done a plastic mesh for thanks before, no problem.

A few points i'd like to emphasise on;

-Those items would be back up options if my dehumidifier and air exchanger had problems getting rid of excess humidity during the winter only( december to march), night time mostly ; i'm the only guy who had to use an ice scrapper indoors when i had my 65G

- Making a net for me is no problem on a conventional tank, on a rimless if i ever decide to get difficult fishes ; at the factory they have all the tools to make a professional job.

- I'll enquire with the manifacturer what i'll use to make the screen cover, before agreeing, metal like you said might be a bad idea, thanks for that precision... I would also monitor my oxygen level if i ever had to use the glass, which would only be a temporary measure during the - 40oF we get and the humidity couldn't be taken out with exchanger.

My question is essentially, would it be a good ideal to have both items made professionally if i need them in the future, not as a permanent fixture but as an option in a crisis or emergency, i guess thats what i was aiming at. Thank you all for your time.
