Product Questions
Hi,
I am looking to buy this product for my turtle tank, which has multiple lights, including a heat lamp, that rest directly on the lid. Would the netting be able to hold the lamps safely in terms of both, strength and heat tolerance?

We would not recommend placing any heat light overtop this screen kit.

What size screen do you use for S-1000 G2+?
Question by: Barrett Bruchhauser on Nov 18, 2023, 1:21 PM
Hey there,
Thank you for reaching out to us. By the dimensions listed a screen size of at least 83"W x 27"L. You might have to look and make two smaller screens to cover the entire tank. Thus making it easier to operate. Either way it will be a custom set up. Please let me know if you need anything further.

There is not a screen for that size tank, you would have to use a combination of two of the 48 inch kits.

do you think one of these screen tops could be fashioned to a 36 gallon top fin bow front ?? even if it had to be 2 pieces ??
Question by: Ralph Derleth on Feb 2, 2022, 3:35 PM
I do not think it would fit well, unless you are able to successfully heat and bend the metal frame. Which I have seen done on You Tube.
Answer by: Matt Lucero (BRS Staff) on Feb 3, 2022, 9:47 AM
Hey guys just curious what kit I would need to buy I have a 65 gallon rimmed tank with a center brace. Just curious if I need to buy two kits the tank is 36" long an 18" wide. Thank you
Question by: Tim on May 1, 2020, 1:24 PM
Hi Tim,
You can either buy the 4 ft kit which will make 2 screen tops up to 2' x 2' or you can buy the 3 foot kit and 4 extra corners and a 3 ft rail.
I hope this helps!
Happy reefing

what set up would I need for a 72 by 18 split in the middle 125 gallon tank
Question by: mike haines on Feb 5, 2019, 4:03 AM
Hey there!
For tanks with a center brace like yours, you would likely need to build two kits for each half of the tank. The R42081 36" X 24" CUSTOMIZABLE DIY AQUARIUM NET COVER would be needed for each half. :)

Will the light mount cut outs on the 36 by 24 screen top allow enough room needed to use the ecotech rms mounts?
Question by: Jordan on Jan 3, 2019, 11:11 PM
Thanks for contacting BRS!
In order to go around the RMS brackets, we recommend these universal cutouts as the RMS bracket would be too large for the regular cutouts. Have a great day!

Do these come precut for the Red Sea tanks? IE for the overflow etc.
Question by: Douglas Lee on Mar 22, 2018, 3:56 PM
You'll need to cut the frame to customize it to your tank. You can view this video for more information - https://www.youtube.com/watch?v=qLNQsKHyUD0.
