brandy3392 I use a piece of non-adhesive shelf liner to cover the hole in the lid of my Spec tanks. The shelf liner is clear, flexible vinyl (or plastic?) with a ribbed texture to it. It does not seem to affect tank lighting, and is heavy enough to stay in place on its own. I cut a little hole in mine to make feeding easier. I'm sure there are better solutions, but this was cheap, easy, and doesn't look too bad. It also greatly reduces evaporation and keeps the water much warmer. I paid about $6 for a large roll at Target.

daffyfish Any type of plastic or glass will diffuse the light a bit. But, shouldn't be a big concern. You could just buy a piece of plexiglass and use a dremel to cut the slots. Or maybe, cut a piece of light diffuser (egg crate) to fit.

So helpful!

Stumbled across this forum & thread as I got a new Spec V for my african dwarf frogs. They were a gift - came in one of those little tiny plastic cubes. They needed a new home! Got them finally set up in the Fluval and they are so happy. But then today I saw one of them trying to squeeze through the lower opening to the filter side! Ack!

So found the suggestion about the electrical tape - BRILLIANT. Never would have thought it would stick when wet but it did! I only covered about 3/4 of it just in case the water level ever drops before I notice it. More than enough coverage to prevent the little fellas from entering the black hole to death.

Then I saw the suggestion to reduce flow by putting nylon over the black return valve. BRILLIANT! Found an old pair of knee-highs and cut off the thicker top part, rubber banded it across the valve, and boom - about 1/4 of the flow that was coming out. (though I kind of think they were having fun taking the Rapids Ride, as I was calling it)

NOW - I haven't found any good suggestions yet about how to cover the hole so my little sweeties can't end up dehydrated on my desk. They haven't tried to jump out yet, but I plan to give them floating plants at the top, which would give them the perfect springboard if they ever thought the grass could be greener elsewhere. I don't want to restrict the light. If I put a solid piece of plexiglass over the opening, would that adversely affect the tank? Ideally I'd like a clear plastic piece with slots, but I have no idea where to find such a thing. I wrote to Fluval, and they basically replied "nope, we have nothing and have no suggestions for you."

Thanks for such a great thread!

I cut a piece of lighting diffuser into a small piece with 2 squares, one of the squares gets a notch cut out so it can hang on the glass and then I used some leftover sponge to hold the plant snugly in place but drilling a hole and using a suction cup might've been easier.

HC coming up from the roots clogs it hard.
Interesting could you post some pics if possible? I'll post some of my setup tonight after work.

I also just fabricated a little pothos plant holder out of egg crate that sits perfectly in the back chamber, I'll monitor the roots so that it wont come close to clogging the pump.

Did you use the same bubble filter?

Has anyone used one of these? I really want more space so I'm thinking of removing the compartment.

Amazon.com : Lee's Triple-Flow Corner Filter, Small : Aquarium Filters : Pet Supplies Amazon.com : Lee's Triple-Flow Corner Filter, Small : Aquarium Filters : Pet Supplies

Any other ideas for a filter once removing the compartment? My tank is for a betta, but I hate the way it is set up stock.

I can't post any pictures atm but I can answer your questions to some degree. I covered up the slits seen in the pics below to force the water to go through the filtration chambers.

As for the pump it was able to fit in the back chamber with room to spare, it's able to orient itself in different positions making mounting very easy. Although the pump is a bit smaller than the original it's heavier/beefier and very well made, also the stock hose fits on the pump no problem. The flow is much stronger compared to the original so much that it significantly lowered the water level in the back chamber by 1.5".

The mount that the pump comes with is was too big to fit so I made my own using; scrap plexiglas, the stock foam, the suction cups the pump came with and zip-ties. I drilled 6 holes in the plexiglas 4 of which are for the suction cups and the remaing 2 is for the zip-tie, I used the stock foam to surround the pump to dampen the vibration (Pump is very quiet regardless) then I zip-tied the pump with the foam to the plexiglas. I made sure that the holes for the suction cups were smaller than normal to ensure that they would not come out.

(Pictures below are not from my setup)

So far I've;

- Covered both overflow slits with small pieces of plastic and silicone
- Replaced the stock pump with the Hydor Centrifugal Pump 70
- Replaced the stock sponge filter with a 4 tier egg crate media rack with (Top to Bottom) Polyester pillow batting, a cut out piece of stock coarse sponge and 2 ceramic bio media pouches
- Added a 10w heater in the pump chamber
- Used a piece of plexiglas to cover a majority of the slits for a surface skimming effect

I can post some pics upon request.

I just used some filter foam.

I just cut a square block of filter foam and put it underneath the stock foam on my spec 3. It raised the stock filter foam up so the small bottom hole is blocked by the foam and the foam also is now high enough to block about half of the intake grate at the top. Should keep shrimp fry safe and only slows the flow a little bit.

Is there a problem doing it this way? Seems a simple solution and im surprised more people havent done the same thing.
