I've noticed so many threads on Fluval Specs lately, and I know I personally love my tank.
So wether you've got the Spec 1, 4, 5, 194738, if you've got some lighting that worked for you, or you did a trick to the equipment, added something, replaced the filter, please comment here!
If it works for you, comment. If it doesn't work for you, still comment! It could really help all of us out collectively to have it in one place.
I'll start off with a few things I have learned in the next post!
1: The tank is really nice, but you could always replace the filter. The black section is easily removable, and you could stick in some normal filter and still use it like that, just have the extra deep space.
2: If you hate the frosted glass, and you want to try out the idea in #1 (keep in mind that is kind of a permanent mod..) you can put normal scotch tape on the frost, and it makes it see through again. I personally like it the way it is, so I haven't done this.
3: I've looked for different filter ideas, or how to make it better, but I feel like for keeping fish and baby fish, you should put a nylon stocking rubber banded over the outflow if you have the stock black outflow unit.
4: The filter slit at the bottom is/was a huge issue for me. I'd love for different successes and failures on it, but I realized that plugging it completely wasn't the best idea. I put a plastic mesh cover on the front of the sponge cartridge, and when I slipped it down, it kept my shrimp from getting back there. I learned the hard way, they can, will and do get back there and die.
That's all I've got for now! I hope people like the idea of the thread!
I haven't really seen a reason or need to modify mine yet. The filter seems to be just right (flow wise) for the tank, and it has a huge amount of media compared to filters with similar flow rates. I also see no point in replacing a built in hidden filter compartment with a HOB filter. I also haven't had much of an issue with shrimp getting into the filter compartment, but the easiest way to fix the issue is by lowering the water level so that it is barely above the overflow strainer. That would likely reduce the flow of the filter, so it might be a good idea to put stainless steel mesh or something behind the strainer.
Maybe you're thinking of the Finnex Ray II. Those puppies *16" or 18"* would put me squarely in the medium light to the high light. Those would require injected CO2 and a rigorous fert regime.
I'm going to try and see what effect plugging the slit has.
Also, does anyone cover the grates as well? I'm afraid the micro rasboras i'm planning on getting will cross over to the filter side through those grates.
The water should still cascade over the top of the divider, no?
The filter itself was never an issue for me however I did place a sponge over the outflow nozzle to reduce flow for my betta. I also did not like having that extra slit that allows water to bypass my filter media so I simply placed a piece of acrylic I had between the sponge and the wall. This all but sealed that little slit. For lighting I am using the Fluval 13 watt PC fixture. Those are the mods I've done and it is still a happy Spec!
I think it'd be wise for everyone to explain which tank they have (or which one they're talking about) to place modifications and problems into perspective.
You could put the intake for the filter in the rear chamber and still be able to use the surface skimming ability of the wall. Then you can place the spray bar along the long side of the tank, if it'll fit.
Also been thinking about a small canister - placing the input and out put in the filter area.
Only think holding me back is I like the self contained cleanliness of the set up.
This is my fluval spec V I’ve had up and running for about 3 months.
Currently have 2 threadfin rainbows, 3 danio galaxy, an oto, and 2 CRS and 3 ghost shrimp. Since setting up the tank I’ve only lost 1CRS to what looked like a molting problem, but that was just a couple of days after introduction - the other two have seemed fine for 2 months now.
The plants are all stock plants from Petsmart, but have really done well. Currently 25% of the water is changed weekly, with daily Excel doses.
The only modifications I made to the setup was the addition of an off brand LED light (8000K white/12000K blue) and an AquaClear 20 powerhead to get some water agitation for increased CO2. The tank is divided up into two minor eco systems. The left side is brighter, open, with faster water movement. The right side is darker with slower water movement. The oto loves the quicker brighter side, while the shrimp hang out more on the darker quieter side. I gave up taking pictures of the fish, they move to fast.
I have been surprised at the plant growth. Need to get in there a do a little aquascaping, but some tools bought on Amazon are wrapped and under the Christmas tree.:icon_wink
Thanks! One of the things that attracted me to the V was the sleek stock light. But now it is driving me crazy - very difficult to work around it if you need to get into the tank.
What would be the easiest way to plug/cover the bottom intake without emptying the tank? I was planning on cutting some of the black filter foam and using some tweezers to compress it and fit it in there.
The only modification that I've made to my Spec V was to cut a hole in the outflow line coming from the pump. That has kept the water level up higher in the pump chamber, so that my heater is properly submerged. This combined with the flow turned all the way down means that I don't have to sponge off the outflow pipe to reduce the flow.
I will also be blocking the small slit at the bottom, because it bothers me that water is bypassing the filter, and I do plan on adding some shrimp.
I know that a reverse UGF was mentioned, but has anyone connected the pump outflow to a sponge filter? I was thinking that it might add another good surface for shrimp feeding, and help to keep the flow down a bit more.
Yes, exactly. The spec offers very little mechanical filtration. So if the biologically filtered water was driving a sponge filter, there would be more mechanical filtration and probably much happier shrimp.
The spec has that huge sponge in the filter compartment. I wouldn't call it "very little". The biomedia it comes with its plenty for shrimp (the huge sponge also holds beneficial bacteria). The only concern is aeration. This can easily be improved by aiming the filter outflow nozzle up and keeping the water level slightly lower to increase surface agitation. An airstone would also work just fine.
I finally got a picture of my decidedly low-tech solution to the bottom filter "intake" (read: deathtrap filter bypass of DOOM!). Since my substrate is sloped high on that side, all I needed was a little piece of plastic courtesy of a Littlest Pet Shop package from my daughter.
For some reason, I couldn't keep my substrate up over it. Probably didn't let it settle enough. I suppose I could have put more after planting, but the little plastic thing isn't really noticeable ... also, if I really, really need to open the deathtrap for some reason, it's very quick to remove and replace.
Glad others are posting about this. I had it with that little slit on the bottom of the spec v. Always had surface film. Cut a small piece of plastic from a strawberry container and super glued it to block it entirely. 2 days now and the water is much clearer and no more surface film. I can actually see the water moving into the sponge compartment. Just a note, I have the pump at lowest setting and make sure there is plenty of water in the tank to run over the intake. Great little tank now.
