Like, just going for it!

The very best part about owning a company like Tannin Aquatics is that, although we're associated with stuff like blackwater aquariums, we offer materials and ideas for stuff which has applications for all sorts of unique displays. Some of the ideas that I have personally played with over the years have been a bit, well- unusual...As have many of yours!

And of course, the idea of pushing limits and trying altogether new stuff in the hobby always makes me smile. It's fun to push the "outside of the envelope" a bit, isn't it?

Have you ever done something with your aquariums that everyone said was just...nuts? More important, did you get away with it, or did you "crash and burn?" Did you at least try something that the “aquatic establishment” said could not be done, or SHOULD NOT be done? 

Wasn’t it fun?  Maybe even expensive?

Embarrassing, perhaps… 

But fun, right?

Did you try something “different” than what “they” say is the way to go?

I mean, something ill-advised, sort of crazy, off-the-wall, or just downright kooky? Or, did you act on one of those ridiculous ideas that someone threw out when tossing back a couple of beers with the gang after the conference or club meeting?

Something totally wild?

("Honey, look what I did in the living room while you were away!" )

As one who has been known to take a few chances in the hobby, go against prevailing “aquatic wisdom” (I mean, shit- I created a company that sells leaves and twigs, right?), and generally push the outside of that envelope a bit (as well as encouraging others to indulge in similar foolhardy adventures), I have developed an unofficial “classification system” for such "nonsense."

Yes, only I would actually study this ridiculousness. (And to think, some of the major freshwater aquarium conferences STILL have yet to have me as a speaker! Wonder why? LOL)

Of course I’m going to share it with you, because it’s important for me to continue to nurture "disruptive" behavior...Besides, I don't like to be the "point man" for all of this stuff if it fails, right? Pressuring your friends to do crazy shit...Well, that’s what makes the hobby great, right?

I think I have this sort of figured out...So, in the time-honored tradition of me analyzing the shit out of every obscure approach to the aquarium hobby, here we go, with the “1-to-4 Fellman Scale of Innovative Aquarium Thought”:

1) Ill-Advised Ideas- I’m probably most guilty of this one, along with the majority of aquarists who dare ask the “establishment”, WHY? And not all of them are smart..I freely admit. Examples of this would be things like the time I was convinced that I could keep 4 Black Ghost Knifefish (my all-time fave fish) together in a 75 system without calamity or bloodshed. It was exacerbated, of course, because I went with mature specimens (like 5")…in an intricate wood and rock hardscape! After the days (yeah, DAYS, not weeks or months) went by, in addition to relentless territorial battles reminiscent of those which occur in the tribal areas of Afghanistan, my prized fish collection was showing signs of, as one of my friends eloquently put it, “wear and tear…” 

You can imagine how fun it was to break down the aquascape  after I came to my senses and decided to end the grand “experiment.” Hey, this one was a product of my own arrogance, and I was really convinced at the outset of the experiment that I was to be THE ONE who could pull this off. 


But it was interesting. For like a few days...


2) Sort of Crazy Ideas- You DIY-types are usually more “guilty” of this one…You know, stuff like automated top-off systems that involve dosing supplements, surge devices in your living room, 4 chambered recirculating CO2 reactors, biofilm refugiums, homemade refrigeration systems for cold-water reef tanks, automatic frozen food dosers, etc. I mean, these ideas are usually pretty cool, and represent many of the great values that we have in the hobby (the independent spirit, adventure, the pursuit of knowledge..the desire to save a few dollars…)

Some of these ideas are just a little too "advanced" for our skills or the avialable/affordable technology to pull 'em off, or perhaps there isn't really an inexpensive way to make an all-in-one-surge/auto-feeding system for under $2,500USD. Well, maybe there is…And it’s just that kind of thinking that keeps the creative (well, you can call them “sort of crazy”) ideas flowing…


3) "Off-The Wall" Ideas- This is typically the realm of newbies..or even experienced hobbyists- who, because of their genuine innocence, love of the hobby, and/or “Why CAN’T it be done?” mindset, come up with some of the craziest ideas of all- and often execute them, albeit with mixed results. I think we should really consider them “outside the box” ideas, however.

Ideas like Hydra “farms” for nutrient export, moss ball denitrification “reactors”, backyard seagrass propagation systems (Hey, I did that! And it worked!) , multi-level gradient cryptic zone filtration systems, etc., which have a great theoretical effectiveness, yet may be challenging to apply in reality.

("Fellman, you can't grow tropical seagrasses in your backyard in Los Angeles" Well, I sure as hell was gonna try...And I DID!)

Nonetheless, IMHO it’s at this “level” that real hobby innovations often occur…Stuff like electronic monitors/controllers for aquarium functions, unique foods, controllable internal pumps, breeding setups for fishes like Hillstream Loaches, creation of all-botanical substrates, the "Urban Igapo" idea, etc....

Many great companies, both in and out of the aquarium hobby sector, were founded on just such a mindset. And, you’ll recall, it wasn’t all that many years ago that the idea of cutting up frags of coral to grow out on ceramic plugs for sale seemed pretty “off-the-wall”, right?

Yeah. Challenging that one played out pretty well for me...


("What a crazy idea...It'll never work!" F -ck you. We're gonna try!)

4) Downright Kooky Ideas- This is the type of stuff that gives our hobby the appearance of being a bit, well- eccentric- to outsiders. Stuff like converting indoor swimming pools to mini African Rift Lakes, 10 ml "ultra-pico reef tanks", creating an intertidal mangrove biotope with a 12-hour "tidal cycle", etc. etc. Look, I’ll be the first to tip my hat to the dreamers, free thinkers, and even the eccentrics among us. However, I’ve always been a bit of a realist…I mean, counterproductive, hurtful, and idiotic thinking is never in vogue.

Yet, where would we be without the truly absurd stuff to give us some: a) comic relief, b) measure of how serious we take this stuff, and c) ability to let our passions (and our checkbooks, all to often) run wild from time to time? Brainstorming is great…Bringing down the ideas from the “downright Kooky” region into the “Off-The-Wall” territory results- many times- in some of the best hobby innovations that we have ever seen!

So, my dear fellow fish geeks, don’t be put off or led astray by “conventional” aquatic thinking, if there even is such a thing…Rather, allow your mind to wander, your passions to soar, your visions to take flight- and your dreams to come true. Don’t put them out with the “wet towel of negativity…” Rather, temper them and nurture them with the spirit of innovation.

And enjoy the process of executing on them...

Keep those ideas flowing, visualize a way to make them become practical realities, and think about the greater good your developed dream will unleash upon the hobby. Disregard the spills, glued fingers, frayed nerves, short circuits, cracked aquariums, and occasional insurance claims,. Think of the bigger picture: The conquering of new worlds, the sharing of new ideas, and innovations as yet undreamed of, which will forever change the hobby for the better. 

Or, just savor how everyone will react-good or bad- when you execute one of your strange ideas. Maybe they'll diss your ass...or, maybe they improve and build upon your idea, taking it in a positive direction that you never could even imagine! Provoking reaction from the aquarium community is almost always a good thing!

Don't hold back for fear of criticism from your peers. That would be foolish and downright tragic.

I close with a classic quote, often attributed to the great Mark Twain (but supposedly not his...), which actually holds much relevance to this diatribe:

“Twenty years from now you will be more disappointed by the things you didn't do than by the ones you did. So throw off the bowlines, Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover.” 

So yeah, you should try.

As one of my aquarium hobby mentors used to tell me, "Like, just go for it!"

Don’t shoot down that wacky, sleep-deprived, alcohol-induced idea that you and your buddies concocted at 3:30 AM at an Aquatic Experience or Aquashella conference…even if it IS “Downright Kooky!”

You never know...

You just might chance the hobby forever.

Let’s hear of your triumphs, tragedies, absurd ideas, and amazing innovations.

Stay idealistic. Stay creative. Stay unbridled. Stay open-minded. Stay honest. Stay diligent.

And most of all… 

Stay Wet.

Blackwater tanks are fun to experiment with :) My 5 gallon blackwater tank is only 2 weeks old and has already been at the center of numerous fun experiments, such as making a DIY DI resin filter to soften my water (it worked! :) ), testing how to acidify and fertilize the tank while adding as little TDS as possible (again, quite successful), and various others…I am adding plants to the tank tonight (I have been acclimating them to the extreme conditions in a QT jar over a couple of days), and when I add them I am going to experiment with using the respiration of the tank’s inhabitants (bacteria, fungi, plants, etc) to produce enough CO2 for better plant growth by turning surface agitation off one or two hours before the photoperiod and then turning it on again once the photoperiod is over (to avoid gassing the tank out). The tank won’t have fish for a few more months, so for now it’s my science experiment :)
