Greetings from Manitoba Canada!

I Managed to score a ~70 G Custom Built European Braced Aquarium For $50.00 CDN off Kijiji.ca. I decided after years of reading about the different aspects of Planted aquariums, paludariums and ripariums to start a project taking all the techniques I admired and incorporating them into my aquarium. This is my largest aquarium to date and I already know I want a bigger one!

The tank itself 48"X18"X18" - Brand new, purchased from a photographer who used it for one photo shoot

Necturus maculosus (Mudpuppy) - Will be the apex predator in the tank. I will also be including a few other species of local baitfish varieties (which I will be breeding in separate tanks) Dace species, Shiners, Sculpins and Johnny Darters etc.

Decided on constructing a river Manifold (special thanks to Martin Thoene- article author) for oxygen and waste circulation. as Necturus are ussually a calm water species I may only end up using smaller powerheads.

Basic Stand design (I modified the actual stand to suit my needs) special thanks to koipoloi over at Aquarium Central for pointing out how great Google sketch can be for this kind of thing I highly recommend the program for the visual planning stages of any DIY project

The trip to home depot, one of many with A LOT more to go lol

Semi-complete stand with prototype river manifold squeezed inside.

I will be using a combination of: eggcrate, silicone, expanding foam, rock, branches and roots to create a background.

Filtration - I would like to put together a sump with overflow box to turn the tank over at least 900 GPH (I really want 15-20X/h filtration). I'm trying to optimize a design that would be wet/dry trickle through bio balls that will fit under my stand possibly up to 50% of the size of the main tank. Hopefully with enough room to put a breeding/ fry tank under the stand along with a chiller to keep the water temp below 70 degrees.

Lighting:TBA - more than likely lower output flourescent w/ lunar LED

Will also be incorporating local varieties of lake plants and invertibrates.

Might even start a redworm farm in my closet (should have seen my ladies face when I said that at dinner, sort of like --->:irked:)

I will update asap and if you have any suggestions, insight or comments feel free to chime in! especially with equipment suggestions or links to relevant articles.

PS I am new to MFK so be easy! :nilly:

Maxx.

Very interesting project and great start. Thanks for all the pics!


My compliments to your stand design. We see a lot of people asking for guidance in building and this picture perfectly illistrates the best way to do corners. The perimeter boards sitting directly on top of the verticle suppport so the weight of the tank is transferred directly to the ground.



Take your time and really plan out the background with deep water and shallow wading areas. I've made many backgrouds or inserts out of styrofoam using Drylok to coat/seal it. Drylok is great stuff and can be tinted with standard paint pigments to creat any color under the sun (tip: add 2x pigment to Drylok compared to typical house paint).



Personally I would have went without the center support and would have made it so a 75 Gal could be inserted into the bottom. Using a 75 gal as a 'sump' for a 70 Gal filled with 30 gallons of water would surely offer enough space to double as a holding/breeding tank.

I have a rack with two 50 gals (48" x 18" @ 13" tall) stacked above a 75 Gal 'sump'. It's really nice having three seperate tanks plumbed together as a single unit.

Honestly, I would add little to no bio media to the bottom tank. Even if you only use a 40 gal (30 gal of actual water int he sump) you will be doubling the overall water volume of the system (the solution to pollution is dilution) in addition to having plants aiding with 'filtration'. I also suggest researching swamp bugs and learnign what to collect to add to your ecosystem.


Great project, I'm looking forward to it's development.
 
Used egg crate and GE II silicone for rear wall and floor, then found some clear acrylic to experiment with and made an overflow box in about 2 hours. picked up some great stuff and will be rockscaping soon hopefully. want to create some rooted buttresses for the little critters. Thank you for all the feedback it helps me find a lot of articles and ideas I may have never thought of.

Brilliant input bud :thumbsup: might take out the middle support next weekend and stick a 50-70 in there. it would almost be a freshwater refugium. the species im looking at breeding would primarily be marmorkreb. I am absolutely fascinated by the fact they are such a hardy and easily cloned specimen. the babies will make an excellent source of food for Necturus or in case I cannot locate any maybe a puffer. I've been trying to hold back purchasing any crays until I can put together an RUGF for my breeder tank. if I start on those crays too soon (notorious producers) i'll have to move them to a larger container, maybe a boiling pot of water if you catch my drift lol
 
I'd never heard of Marmokrebs, so after a quick google, they look like a great crustacean to keep as feeders. Thanks for bringing them up :)

Your setup is looking very solid, can't wait to see how it turns out :)

Best,
Paul
 
I think Marmokrebs are going to be the next big thing with live food. But alas it will probably be short lived as some un-educated person will release these into the environment causing them to be banned in my province.
