Yes but some people got openly offended by my series of posts about filtration. Who knows how many more people quietly died in agony from my writings by being forced to read sentences with more than 4 words and having to think a little on top of that.

Now, with this translation things are black on white. Let's see what kind of a wave this will make. A tsunami or a storm in a teacup.

Also I think that the Laminar flow thread is not entirely a pipe dream as it may seem to some. I actually think that we can ultimately combine knowledge from different source into an optimal and reasonable guide to setting up and running a planted tank. No empty claims. The Dutch are not big on light periodization but Amano is. The Dutch do not believe in special water flow throughout the tank but Amano does. Things like that. To combine all that seems really promising but only if it is done with enough knowledge AND common sense.

People who seem to get offended also seem to be those who are closed-minded...but then again there are also folks who would love to look into things but are just so busy that they are hoping for the quick answer. Unfortunately it's nearly impossible to give a quick answer to something so complex.

I am excited about the filtration information coming to us by the truck load because my goal is to not only have a beautiful and sparkling clean aquarium, but to understand what's going on inside it. This will allow me to better address issues that come up, and will probably prevent most issues from coming up to begin with. There's a reason folks say that knowledge is power...

I noticed something interesting last night in this tank. Under 5 Anubias leaves and 3 Ludwigia palustris leaves (still need to confirm that against L.repens) there were pearls. I don't dose CO2, and the lighting may be high for a tank this size, but 20 watts of pig-tail lighting can really only do so much. I guess the organics I started this experiment with are breaking down and are now in the water column.

The water is clear by the way. I moved some plants around and stirred up all kinds of junk, and within a couple hours it was as if I hadn't touched it. I don't ever test chemically for the usual things people test for. This experiment was mainly to show how different filtration set-ups effected the visual quality of the water. Maybe the tank is just too small to benefit from any increase.

Anyway, that's where I am for now.

I put a strainer on the inlet pipe and noticed that due to the size and spacing of the holes, very little of the biofilm goes into the sump now. The biofilm is not very thick, but it is there, and the fact that it does not easily break up and get sucked into the inlet while the strainer is in place leads me to want to explore what is in the biofilm. Fortunately I don't have to get as technical as I had originally planned because Niko posted that website link that Yo-han translated over in the Equipment forum under Biological Filtration. Bascially it is a living unit of bacteria and organics...I'll simply suggest that you read that post for details. It saves me being redundant.

Here are the pics of the strainer, and one of Mrs. Jane the betta who is back in her home.

I'll notice absolutely no algae in your plants or glass although there is quite a lot of light for this size tank. Have you cleaned anything since the setup? Added anything to prevent/kill algae?

Although I run the biggest filter Eheim has (2080) on my 100G, when I do some serious uprooting I'll never get my tank clear this fast. Maybe my next setup needs to have a over-sized sump...

Now that you mention it, no, I've not cleaned it since I set it up, and I don't dose or add anything except fish food. This had been the coolest little experiment I've ever done because the water got so clear so fast that it actually caught me off guard.

Even when I mess with the plants or stir junk up on purpose, it's clear again within an hour. Filtler capacity is DEFINITELY a huge factor in how the water looks. I wish I had the stuff to test it chemically, but I've never bothered with that in the past so I don't have test strips handy.

But the plants are growing, there is no algae, the water is clear, and Mrs. Jane is happy...that's good enough for me

I have removed the Darth Vader canopy and replaced it with the lighting that came with the tank, which is a 9w pc or cf or whatever it's called. I can't stand the color, but I've not found a good one in that bulb and am not willing to invest money in a new fixture.

With the overdose of lighting, I stopped overdosing food (nutrient) and noticed some brown algae formation on the leaves and pipe. I'll let it go and see if it goes away in time. The water is still fine, except that with so much organic carbon load I notice yellowing after a couple weeks and have to do a 50% water change to clear it up (total volume including sump volume).

Since I reduced the lighting to less than half I have also removed most of the plant mass. I'm still traveling a bunch, so whenever I get relaxed enough to want to take pictures I'll post a few.

So far so good. Having played around in the Llano River a lot, I think if I were to set up a larger tank I'd go with about double the water flow (between 14-18x volume per hour) with an outlet that is more open (kwc1974 has one that would be an example) so not so much turbulence, but plenty of water movement. I like the drain as an overflow rather than the water being pulled near from within.

I shot a couple of video clips showing the difference between "tubulent" versus "laminar" flow by stirring up the debris. I have never successfully uploaded a video, but I'll give it a try.



Okay, so I am a vitual caveman technologically speaking. I'll try stashing them and posting a link...

Take 2...maybe this works.

You can see the ill effects of the 9w bulb (puke yellow, or bile yellow?) as opposed to the previous lights I had on it with the 10gallon hood. If anyone knows of a bulb that will work with the 9w pc fixture that is not horrendous please let me know...

Just click the pics; they are the video links to photobucket...(you may have to be logged on to APC to see them)
