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.

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.

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.

Overflow/Protein Skimmer

Hey everyone!

Been testing this mod for the past few days and have to share it with you all. I recently noticed the formation of a film on the surface of my fluval spec iii, so I set out to fix the problem. I went online and researched solutions, eventually deciding to order an inTank protein skimmer. IME it did help some, but the top of the water was not crystal clear like I was looking for. Feeling diy, I went to my local hardware store and bought a black paint tray (the ones you use with a roller brush). This was perfect because the material (Polyethylene Terephthalate) would be aquarium safe and the shape of the paint tray would later prove to be perfect for my application.

Process
The idea was to create something similar to the inTank skimmer, but mine would cover all of the grills instead of leaving open gaps on the sides (which shrimp can get sucked in to!). With the paint tray in hand, I cut a flat rectangle out of the bottom and zip tied it over the spec's intake grill. A little while later, I looked back to see how the skimmer was doing and... nothing was flowing over it! The surface tension of the water was too great and the water was simply taking the path of least resistance and going through the vent at the bottom of the tank (you all know the hole I'm talking about). So I plugged up that hole and set out on my next and final design. This design utilized the shape of the paint tray more, taking advantage of its sides which had ridges and curves.



Maybe it because I plugged up the bottom "vent" hole this time, but the new design worked! The top of the water is now free from any and all scum. And I have the added bonus of a consistent water level in the front of the tank, with only the level in the back compartment fluctuating (make sure to top off back there on occasion or you risk damaging your pump! I hope I did a good job explaining this, it's quite a hard process to put into words. For anyone looking to buy the same paint tray as me, I got it from Ace Hardware. And for those of you who are eyeballing my beard moss i'm still cycling the tank, it should be clearing up soon!

The_guad I created a third chamber in the filter compartment of my spec III. Now, I have a middle compartment that the water flows up through, past my mini heater and then over and down to the pump. The temperature in my tank is now very stable at 80 degrees with a 10w betta heater where I could never get it to change with a 25w heater.

Here are the materials I used:
1 x Dollar store cutting board (thin and stiff)
1 x Silicone airline tubing (I bought 8ft but only needed 17")
1 x hot glue stick and hot glue gun

First, measure your space to determine how wide and tall the divider needs to be. Mine was about 2 1/32"w x 7"h. The height was determined by the lowest point in my filter intake grill and just a bit shorter to make sure there will always be flow so long as water is coming in to the filter. The width was determined by the piece needing to be close to snug but still having about 1/16" of space for the airline tube (gasket) to make it water tight. After you make your first cut, dry fit. If it is too big, cut again and dry fit again. If it is now snug but not tight, proceed to the gasket.

Second, cut one piece of airline tube that will go the width of your divider piece. Split it down the middle and place it on the bottom of your divider. Glue it on with the hot glue.

Third, cut 2 pieces of airline tube to 7" minus a bit to account for the airline tube that is already on the bottom. Split them down the middle and slide on both sides but DO NOT GLUE YET. Now dry fit again.

If the divider doesn't slide in snug, pull the side gasket line off and cut a small amount from the divider (you can't put material back on... go slowly). Put the side gasket back on and do it again. Dry fit, dry fit, dry fit.

Once everything is the way you like it, hot glue the side gaskets on and slide it in. Place your heater in the center of the three compartments so water is forced to flow up past it before going over and down into the pump compartment on the opposite side of the filter chamber.

sockfish This is a great thread, thanks to all the contributors. I've been thinking about how to mod this for a Betta and I see some of the things I thought up mentioned here as workable. Might just use my 20% Petco coupon and try this tank.
