CLEAR VS BLACK SCREEN
AESTHETICS OVER ALL
The biggest visual difference in your lid comes from the screen itself.
Clear Screen
Clear Screen lets through slightly more light PAR, yet glares more visually when viewing the tank.
Black Screen
Black Screen reduces glare down to near zero for a clean and unobstructd view from the top, yet ansorbs slightly more PAR.
FEED DOOR
EASY ACCESS FOR ANYTHING
Never take your lid off for feeding ever again. All Feed Doors are included FREE with every Top Lid.
EASY TO GRAB
Easy to take off quickly, just grab with 3 fingers and lift.
SCREENED, NO CONDENSATION
Screened for full airflow through the feed door, leaving no condensation that needs to be constantly cleaned.
STAYS IN PLACE
Sits recessed inside the lid, to stay in place and not fall even when the lid is moved.
FITS LARGE EQUIPMENT
Large enough to fit all types of equipment through, like algae clips, turkey basters, PAR meters, and magnet cleaners without ever lifting the lid.
CORD CUTOUTS
YOUR AQUARIUM, FUTURE-PROOFED
Future-proof your aquarium for a lifetime. Freely place powerheads, heaters, and probes at any location on your tank. All Cord Cutouts are included FREE with every Top Lid.

UNIVERSAL LIGHT CUTOUTS
A PERFECT FIT, WITHOUT CHANGING YOUR LID
Never worry about gaps around your lights for fish to jump through, or your lid being obsolete if you upgrade your lights.
TRULY UNIVERSAL
Fits any type of aquarium light mount, saltwater or freshwater.
PRECISE, NO JUMPERS
Inserts create a tight-fitting cutout for your specific light mount.
NEVER OBSOLETE
Change lights at any time while keeping the same lid. Only need a new Universal Light Insert.
OPTIMALLY SPACED
Placed at an appropriate spacing for healthy light spread to grow a thriving reef or planted tank. Custom light spacing available on request.
UNIVERSAL AUTO FEEDER CUTOUT
FEEDING AUTOMATION AT ANY TIME
Auto Feeders are the most common type of equipment for hobbyists to not use when starting their tank, but to add later. Future-proof your tank for any brand of auto feeder with the Universal Auto Feeder Cutout.
TRULY UNIVERSAL
Fits any type of auto feeder, so you don't have to worry about which you'll go with in the future.
UPGRADE FEEDERS
Changing auto feeders is as easy as swapping out an insert. No need to reorder a new lid. Only need a new Universal Auto Feeder Insert.
PELLET / FLAKE COMPATIBLE
Small pellets fall directly through screen on insert. Optional Auto Feeder Cup for larger pellets or flake food.
PROTECT WHEN REFILLING
If cleaning / refilling your auto feeder or don't have one yet, "Blank" Inserts fully cover the cutout.
EVAP COVER
KISS EVAPORATION, SPLASHING, AND WET CATS GOODBYE
Nobody likes constantly topping off the tank with new water, big fish splashing water around their room, or cats inside their tank. Solve all of these with an Evap Cover.
LESS MAINTENANCE, MORE STABILITY
Cut down evaporation by 60-75%, reducing water top offs by half and stabilizing your tank's chemistry.
NO MORE SPLASHING
Stop even the largest of splashers from making a mess of your stand, floor, back wall, or even ruining your lights.
CAT-BE-GONE
Your fish tank is not a litter box. Keep curious cats where they should be...out of your tank.
THE PERFECT MATCH
Best used with a Luxury Lid. Vents in the lid frame promote maximum airflow, normal oxygen and heat exchange, and greatly reduce the condensation on the bottom of the Evap Cover.
FOOD REGULATOR CUP
THE FROZEN FOOD SOLUTION
Take the time out of feeding your fish. Never defrost food yourself again. Feed any type of frozen, flake, or pellet food in 10 seconds or less, dispersing equally throughout your entire tank.
KEEP EVERY FISH PLUMP
Disperse food over time (2-4 minutes) to make sure even your smallest, most timid fish gets well fed.
TIME-OPTIMIZED FEEDING
Feed your tank in 30 seconds or less. Put the Regulator Cup in, throw some food in, and walk away.
AUTOMATED FEEDING HAVEN
Also available for Auto Feeders, slowly dispersing large pellet and flake food into your powerheads when you're away.
EASILY REMOVABLE
Fully removable for cleaning and to keep the sleek look of your tank.
Customer Reviews
As I began the process of buying a new tank I also began looking at lid manufacturers to decide who i would go with as we know lids aren't cheap. Every other vendor just had me fill out a form online and the response back took 7+ days, with toplids I sent in my online form and the next day Tyler calls me up to discuss the project. That made my decision quiet easy to try out toplids.
I purchased custom tank through CDA in California, through the process I kept Tyler in the loop so that he could get the measurements so the lid arrival would coincide with the tank coming in.
Tyler was fantastic, called me up made sure I got the exact setup I was looking for, and the lids arrived a day before the tank arrived.
The lids fit flush to my tank, nothing sticks out, corners and edges of the lid were smooth and clean. All the custom cutouts matched exactly what was requested to fit my plank feeder and 2 feeding slots in the front.
If I add more tanks/replace this is the only place I will order my lids from. Customer service has been on point and to me, that was one of the selling aspects for toplids over its competitors.
FAQ
What materials are your lids made of?
What materials are your lids made of?
Our lid frames are made from polycarbonate, thick enough to thoroughly support the lid, but slim enough to keep away excessive condensation and salt creep. Our screens are individually made for us, with thin screen fibers that let through more PAR than other screens, and openings small enough for even the smallest fish to not wiggle through. These materials are water-resistant, easy to clean, and provide long-lasting protection for your aquarium.
