Deep Sand Beds for Freshwater tanks

  • We are currently upgrading MFK. thanks! -neo
I know I've read about diy diffusers for outputs using bottle caps secured to the output of canister filters to lower the flow for fish who can't handle high flow. that might help a bit if you put together something like that. I know coppers a big no no. I have no experience with pyrite, but I googled if pyrite was safe in aquariums, and I got a bunch of results saying it wasn't. Maybe try a vinegar test? I couldn't find exactly why its so dangerous.
 
Well, it is just a few granules. I'm going to ride this as it sits. Got pics and a vid of the atrocity on the way.

Oh, I solved the sand pit issue with an old sponge filter internal tube. You can see it in the pic from above the trough, but just as a gray blob through the waves. It takes the incoming water and channels it through the tube, out the small holes with some force and out the other end of the tube, too. It's just wiggled into the sand and packed in. Simple is good.

I have ruled out boiling as our good stove burner exploded while I was boiling driftwood and my wife would hang me if I blew the other front burner boiling sand.

hehehehehehe!!! LOL!!! Believe it or not, that would be more merciful than taking the kids, the house, the car, and exacting alimony and child support. Trust me. I know!!!
 
Well, in lamer news, my computer refuses to load the video and pics in my camera...
 
In happier news, the MTS were free this time since they have so many in the gravel at my LFS. They have already buried themselves into the sand. I pushed earthworm-based flake food down into the sand to get the muck going. So far, so good. Like it is even remotely possible for anything to have happened yet...

I noticed gigantic red tapeworms crawling around in a nearby tank. A group of scawny, blackened Peacock Bass huddled in a corner. One juvenile had emerged from hiding and had a gaping hole where his eye had recently been. I had to have a tapeworm so an employee gave me a bag and I rolled him into it. With nowhere else to put him, he's in my aquatic plant arrangement here on the desk. I don't think he'll live long, but it will be fun to watch him for a day or two. He's about six inches long, flat, ribbony and segmented. He coils on contact and is clearly not equipped for life outside the intestine.
 
I have a FW 55 with a wet/dry and a sump on it and I was always fighting with high NO3 about 50 - 80 ppm with weekly water changes. I built a little box around my return pump and covered it with 6 in. of gravel as a mechanical filter to try and trap any little particles before the return. in the past two months my no3 started dropping and it has been at a steady 10ppm for three week with no water changes. the only thing that has changed is a few more fish and the gravel. So far no ill effects
 
Here's the trough as it sits now: I'll start with the earliest shots and work my way up. Not much to the details as far as info goes. Rinsed it a thousand times, put it in the trough, shook it down a bit and ran water over it for a few hours before tank use. Added a few drops of Prime to it and rigged it up.

Took awhile to get the hose right. Had to mix and match until something worked. Now we wait.
