Nature Center Opportunity

They would like us to help them convert this tank into a native fish display. They are located in the Chattahoochee River watershed and would like to feature their local fishes. With a tank of this size we have lots of options; but since Luxilus zonistius is unique to the Chattahoochee drainage, some of these will certainly have to be featured.
I would like to have a couple of different activities this spring/summer. On one weekend we need a team of volunteers to reconfigure the tank. If we empty the tank of its current river rock substrate and use a sand and fluorite mixture we should be able to create a substrate that will support the growth of Vallisnaria and be clean and easily maintained by the staff of the nature center (although I also anticipate that we will be asked to help from time to time).
Additionally we will need to collect appropriate numbers and species of fishes to inhabit the tank. This should be the fun part for most of our members, along with seeing the final display at work teaching people about our native fishes.

Here are some pictures from Andrew Nguyen of how vallisneria grows in pure clay kitty litter:

Andrew Nguyen used uncapped kitty litter in the pictures above because guppies don't burrow or throw up dust at all. Sand capped kitty litter works just as well, and protects the kitty litter from burrowing or high current. Soil also works, but must always be capped.

I wish I lived closer, I'd love to help. Sounds like a great project. It would be awesome if, in exchange for the help, we could put a NANFA sticker on the tank or something like that.
Oh that is definitely in the plans... I haven't actually asked Casper for any stickers yet... but I am going to make sure that we have something on there!

If you're going through all the hassle, save yourself and please make sure they are in it for the long run.

I have to agree that kitty litter ... or it's even slightly cheaper equivalent, Saf-T-Sorb from Tractor Supply (and other sources I'm sure) ... is a FABULOUS substrate for growing plants. Under $5 for a 40 lb bag. My plants are OUT OF CONTROL, unlike any modest success I've ever had before. (Granted, some maintenance is overdue.)
If this is going to be a velocity tank, some gravel and/or sand topping would be good though.
A 240-gal tank is big enough for the "full Todd Crail Ultimate Aquarium" treatment, with a large variety of micro-niches (water velocities, substrates, plants) that would keep a good variety of different fish species happy. <=== My $0.02 recommendation.
Do you have photos or knowledge of the lighting in the top ?

Picture of my old tank. Dropping a tool would not cause a 'dust-splosion' because all that was left was pea gravel sized grains. Note how thin the layer is, only an inch or so, and all large particles. This tank was thoroughly siphoned.

Thoroughly gravel siphoned kitty litter has different properties than non-siphoned. Note the lack of fine particles in between the large particles in the close up picture below:
I'm not arguing for or against it in the nature center (I don't care), but I do want to accurately portray my experiences with it. If you siphon it thoroughly and leave behind only pea sized granules, there is no dust from dropping things on it.

I hope we can get something like the "full Crail" with the different micro habitats (we do after all have southern studfish in the watershed).
Right now the lighting is four of some sort of large diameter fixtures that sort of look like reptile basking lights... but I did not even into them to see what the bulbs were... I should have... see that's why I need y'all to help me!
What do they have for filtration?
There is a huge Fluvial thing underneath that looks like a 5 gallon bucket... I think it said Fluvial FX5... which I think says that it is rated for 400 gallon tanks?

An FX5 will certainly handle any reasonable bioload in a 240 as long as water changes get done. Not a fun one to open up and clean, but not problematic. Where is the water supply, where can waste water go? Have you scoped it out in this regard?
I have not. I jumped to the conclusion that they would not have a problem since they are already maintaining the turtle display. But that is another good thing for me to look into.

The Nature Center staff had removed the turtles and drained the tank down to about an inch of water before we arrived. Some of us worked to remove the drift wood (a single piece over 5 feet long) and the rocks and clean the tank, while others rinsed and cleaned substrate.
We were fortunate that there were plenty of water taps and hose and we were allowed to work in the yard of the Nature Center. Doug had convinced me to use Saf-T-Sorb a fuller’s earth clay that was available from Tractor Supply Co.
I think we used about 300 pounds (7 bags) to lay down a substrate base and to create the two central mounds down the center of the tank. These mounds were created using a readily available nylon based containment system (queen sized and coffee colored I believe the package stated as I purchase 3 pair for the first time ever). We then capped that with 200 pounds (4 bags) of playground sand from Home Depot.
Doug swears by this substrate and this kept our total substrate cost down to approximately $50 based on a couple of well-timed sales at both retailers.
Next we placed the drift wood on top of the mounds, began to refill the tank, and planted the tank with as much Vallisneria as I have been able to grow recently. We also added a healthy dose of Nerite snails that Doug had brought (and I think at least three regular pond snails that snuck in on the plants) and finished filling the tank.
We added two, two tube shop lights on top of the existing canopy (another $45 with daylight tubes). It seems that the existing lights had been re-purposed as part of the move of the turtles. The existing Fluval canister was cleaned and improved with some additional Martix. We got that started and went to bed with the tank looking decent but still a little cloudy despite our efforts to clean the substrate before addition.
In the morning we were greeted by a totally clarified aquarium that was just begging for some fish.
So we pulled out boots on and went down to the little stream that runs through the Nature Center. We came up with a Blackbanded Darter and some Stonerollers and introduced them straight into the tank. Then Kathy took us to a spot she knew of one creek over and we were able to collect a ton of fish (no seriously, I had to carry the coolers out… it felt like a ton of fish). We introduced a school of 27 yellowfin shiners, 6 or so each of bluehead chubs, stonerollers, blackbanded darters, and southern studfish… oh, and a single Alabama hogsucker.
Kind of a larger “first stocking” than I intended, but we came up with so many cool fish, they were hard to resist. They seemed to settle in nicely and most even ate some flake when it was offered.
Two great days of working with great NANFA people!
