Thank you Oldreeferman! Also, thanks again Michael!
Last night, on the 75g stream tank, I scraped off the excess silicone that was smeared on the right side glass when I mounted the rock wall. It was the only way that I could mount it and make sure that enough silicone got in that space in the corner. I am not happy with the scraper that I used, so I'll follow up with a razor blade to get the last little bit off. Man, it's harder than you'd think getting that stuff off of the glass. The excess epoxy that I spilled on the glass comes off easily, in case anyone ever wondered.
I also finished the final touch up work on the wall with the epoxy, so, I'll be able to add water in 7 days to test and maybe start cycling if everything goes well. The big test will be to see of the background holds in place and the roots don't float. Wish me luck!
Up next, paint Drylok tinted with dark charcoal cement dye on the outside of both sides of the tank to hide the silicone glue bond with the wall.
Also, I need to purchase a light. I decided on the Fluval Planted 3.0 fixture, and also will use a glass top for the tank, so I need to buy that as well.
I need to install a revised version of a DIY spray bar. The one that I initially designed can be modified easily, but the old one that would have been draped over the side of the tank won't permit me to use a glass top without cutting it. So, I'll access from the back side. It might require some drilling into my wall or the stand pipe where my canister filter intake is, but that should be easy.
It's time to design my rock scape with the rocks that I collected from our river way upstream. I washed and scrubbed the rocks off last week. I still need to collect some sand, so I plan to do that on Saturday. I could use play sand, but, I want a more natural look. I'm going to try and make this look as much as possible as a river bed. After the tank cycles, it's fish collecting time!

It's all coming together! Good luck with the wall and roots and water! I think you're good.
Since you're collecting your own sand, you could leave it dirty and full of life. Up to you of course. If you did, it should speed up the cycling process. Any plants going in this one?

Thanks Michael...yeah finally coming together! I would like to collect some river stargrass. I hear it does well in aquaria, and also, in gravel. I need to filter out the sand to get insects and trash out of it, perhaps. It depends on where I can collect it. As far as the life goes, that was my initial plan, to help the tank cycle and such. But, with that comes insect larva, and potentially flies hatching in my house! I don't worry about worms much, but leeches, not what I need. So, we will see.

Regarding the 75g FW stream tank: I made progress, but... A couple days ago, I remembered that there is a stream close to my house where I could drive up and park right next to the water. So, I went and checked it out, and sure enough, there was a gravel/sand bar that looked great. The colors and size were perfect. Then, yesterday, I screened, washed and sifted the gravel. Here's a tip though. When you have to carry a 5 gallon bucket worth of wet gravel or rocks to your house from the vehicle, and then downstairs, it's much easier to divide it into two 5 gallon buckets and carry it in balanced. A month ago, when I collected the rocks, I carried the full 5 gallon bucket down and it wasn't fun. Also, washing creek gravel took a lot more time than washing store bought gravel. It seemed like it took forever. I think that I spent a good 3 hours or more washing it. Anyway, here it is divided into the two buckets:
Then, I took the rocks out of the bucket and sorted them out by size and shape, and set aside the ones that I wanted to be seen the most and arranged them on my workbench (which is the stand that I built for my 100g oyster reef tank).
After that, I went ahead and rockscaped the tank, then filled it with water. This was a test run, to see if the wall held up and the roots didn't float. I also set up the powerhead and checked out the current. It ran perfectly. I didn't use this design to achieve unidirectional flow. Rather this current, along with the spray bar, should simulate a stream side eddy and undercut bank. I didn't take a picture because the water was still cloudy, and, I didn't have my canister filter set up. I will have that done tonight.
I also received the light that I ordered, a Fluval Planted 3.0. I'm really happy with it. I plugged it in, downloaded the phone app, and configured and previewed it. It's really cool. And, the best part is that, remember the shiny look of the epoxy after it finished drying, and I was worried about it? Well, what they advertise is true. It really does disappear underwater. Everything should look great when I'm finally done.
However, and now the but... I noticed that the roots stuck out of the water about 1/4", which is no big deal, but, it would have affected my ability to run the spray bar and shoot water over them to simulate the stream. I thought that maybe, when scaping the sand and rocks, that I just needed to adjust it, so, I pulled out the roots, moved the sand and rocks to the right side of the tank, and stuck the roots back in. And...they float. It isn't bad, but, it's enough to mess with my design concept. So, I unplugged everything and will work on fixing that asap. I pulled the roots out and set them in a container to drain them as water does get inside them. I'm not too worried about that because everything is inert that I used, and it enters very slowly. Although, I'm considering another coat of epoxy on areas where water might seep in, just in case.
The roots float at the top of the fixture, moving it away from the wall and up over the water surface. The bottom of the roots seems to stay down, somewhat because of sand and rocks, but, more because there was less foam used there. So, I think that I can leave the bottom alone, and design some sort of hook and latch system at the top, in the back, out of sight, that will hold the roots down.
Next steps include fixing the roots, draining the tank, scooping out the rocks, sand and gravel, add sand and gravel again, rescape the tank, refill it, cycle it, add fish.
The good news is that the back wall held in place, and is firmly attached. I don't think that it's going anywhere. And, the tank doesn't leak. I was worried about spray foam expansion damaging the glass seams, but, they're OK. And, the epoxy shine disappears underwater.
I'm almost there folks. There will be fish in it soon!

Great update! It's always something! A minor setback. I bet it looks great. So close! If you're not worried about them contaminating the water, maybe let the roots soak and get water-logged. That might resolve the issue.
I can't wait to see it!

By the way, congrats on the back wall holding tight. That was a real worry and you triumphed! Hazah!

Thank you Michael and Dawn. I've had water in the tank for three days, and the back wall is holding up OK. So far so good, and no signs of anything coming loose...very tight. I used a ton of silicone and also with the very tight fit against the wall and frame, and the center bracket, all that should keep it in place.
I have an idea on how to connect the roots. I'm going to keep it simple and just use zip ties. I'm going to drill a hole through the back corner of the root, out of sight, and use a black zip ties to create a connection point, then, drill a hole through my stand pipe, and use a black zip tie to secure the root structure via that connection point. Sand and rocks should keep the bottom stable. I can still remove the roots easily for cleaning and maintenance simply by cutting the zip tie to the stand pipe.
Drilling the hole should let a lot of air out of the roots too.
Zip ties are wonderful, and cheap!

Sounds like a plan. I love zip ties!
Hey, are you going to do another thread for this tank? If so, let us know where. I'd like to keep up with it.

Zip ties have come in handy for me for so many things in and outside of my tanks! Awesome invention!
Yes, but I'm not sure if I can post a link to another forum. You can find it on the NANFA forum on the Advanced Captive Care board. It's in the planted tank forum and the cichlid forum as well.

This past weekend, between fishing trips, I made some progress on the 75g stream tank. First, I drained the tank, took out the rocks, scooped out the gravel and cleaned out the silt. When I put the gravel in the first time, even though I sifted it for a couple hours while running a hose through it, it still had a bunch of silt in it.
When everything settled, the silt created a layer of scum that covered everything, including the roots and wall. It actually looked like what you'd see in a real creek. But, I cleaned it off with my hand and a sponge and cleaned the glass as best I could. Some of the silt made it's way into the crevices of the rock wall and root. It actually looks pretty realistic, so I may or may not try and clean them out. I'll wait until I fill the tank again.
I took the gravel and divided it up into two buckets, and decided to clean half at a time. It took me three hours to clean the first half, and it's not perfect, but much, much better. I think that I'll divide the other half in half again, and clean each of those 1/4 amounts one at a time. Maybe it will go faster.
Once I had everything out of the tank and finished cleaning the scum, I put the roots back in, measured where to anchor them, and zip tied them to the stand pipe (picture below). It's really secure now, won't budge, and certainly won't float again. The stand pipe is wedged in there tight to the tank and secure in the wall. I'm really happy how it turned out. There is plenty of room for my standpipe and over the roots current.
If I want to do maintenance to clean out the stand pipe, I need to remove the roots. The zip tie is easy, just cut, take the roots out, clean the standpipe, put everything back together and in, and then use another zip tie. Easy peazy.
After that, I put the mostly clean gravel into the tank, then snapped a pic. Under water, the glare from the epoxy completely disappears. This is the first pic with the new light fixture:
Next steps this weekend (hopefully, I can get them all done)
-wash the rest of the gravel and put in the tank
-redo the rockscape
-fill the tank and reset the circulation pump
-redo my spray bar for the canister filter
-set up and test the canister filter
The only thing else after that is to buy a glass top, cycle the tank, and then catch some fish for the tank.

Hey Michael! I've been out fishing a lot for sure. But, I've made progress. There's good news and some pretty bad news. I'll start out with the good news.
I was able to pretty much finish the stream tank. I finished washing the gravel as best that I could, added it to the tank along with the river rocks that I collected, and rockscaped the tank. I'm not certain that I'll keep it this way. More than likely, I'll remove some of the river rocks. I kinda got carried away LOL. I also purchased a glass top that didn't fit correctly. But, it worked out, because I was able to trim the plastic pieces that come with it to make up the difference and give it a good fit. All I need to do with that is cut a couple of the corners to make room for the canister filter stand pipe intake tube and the spray bar. Oh, yeah, and I finished the spray bar. Once I get the glass cut, then I'll set up and run the canister filter. This should bring the river effect into full swing, adding current across the top of the roots and across the tank. The roots are cinched down tight and are doing their job well, hiding the powerhead. Below are a few pics.

Next up for this tank, cycle it, then get out there and collect fish, then add them to the tank.
Now the bad news... My 20g long oyster reef tank had an ich and velvet outbreak. I have no idea how that happened, but, it did. I had a QT set up with some fish that I recently collected, treating them with copper and Prazipro, so I moved the surviving fish into the QT. One of the blennies was too far gone and died in QT. One blenny seems OK as of last night. One goby is hanging in there. It was belly up on the bottom barely breathing two nights ago, and is at least upright and breathing better, but, is really out of it. I think it could make it, but, I'm not really optimistic. I lost all of the skilletfish, three blennies, and four gobies. Of the fish that I recently collected, I lost two skilletfish, one goby, and a couple small killifish. Most of the fish that were in QT already that I collected seem to be doing better, including a small male blenny. They're still scratching, but, they are better, I think because they're eating again. The oyster reef tank is still running with inverts, but, I pulled the oyster cultches out for some maintenance.
My 20g high tank is doing OK, but, it's fishless. I did collect another anemone for that tank, so that was nice.
Now that the stream tank is up and running, it's time for me to clean up the mess that I left behind and finish my 100g oyster reef build. Hopefully, I'll be able to save the blennies and the fish to have something in the larger tank. Otherwise, I'll have to wait until it warms again next spring to collect more fish.
Lesson learned...when fish aren't interested in food and they haven't eaten yet, they're sick. Take action.

Wow, that stream tank looks great! I agree you've got too many rocks in there. They obscure your awesome fake wall too much.
Sorry to hear of your fish illness troubles. ICH and Velvet is a tough combination.
Nevertheless, I'm excited to hear that you'll get started on the oyster reef build!

There really was a method to my madness adding the rocks though. I wanted to see what they looked like under my new light. Sometimes rocks out of the water, or not under the light underwater, don't look like they do in the light underwater. I want to pick the ones out that I think look the best. The only way that I could do that was to put all of them in. Silly, now that I think about it.
I want lots of places darters, shiners and minnows could lay eggs too, and to simulate a real river bottom. The problem is that I collected enough rocks to stock at 220g much less a 75g!!!

Makes sense to me. You gotta see how they look, then pick the winners.

I'm still losing fish. The largest goby, the one that almost came back, finally died. I have three small ones that seem fine, but lost one of the small ones. The large blenny seems OK, but, isn't interested in food. That worries me.
I tested for copper and the Cuprimine dose seems too low for therapeutic, even though I followed the dosing recommendation. I'm using a Salifter test kit. So, I added 10 drops of copper again last night. I'll keep doing it until I get to the therapeutic level. I don't want my fish suffering any longer.
