I have some material for the oyster reef tank to post, but, no real news on that. However, I've made progress on the 75g stream tank (with DIY rock wall and roots), and will have that up and running very soon. What does that mean for my oyster reef? It means that I'll be done with all of the other projects that are getting in the way of the oyster reef bigger tank project!

So, news on the 75g stream tank: First, I went on a fishing trip this past Saturday, and successfully collected enough river rock for my tank. I need to get some sand and some smaller rocks and gravel still, maybe this weekend. I decided on the new lighting fixture that I want, a Fluval Planted 3.0. It should be perfect for this tank. I will order this light fixture very soon.

Last night, I dabbed on the last coat of paint with a sponge to give it some highlights of a lighter color. I think it turned out OK. It doesn't look that much different than the last time I took pics. I put my shop lights over the tank and took a few pics at different angles.

Basically, my roots and background are almost done. If it wasn't for the next step, that I just decided to do, that will happen as soon as I can. I decided to seal in and protect my work on the background and roots with a clear coat epoxy called Polygem 1319. I've read good things about it. For example, it looks not so great without water in the tank, that it shows a shiny coat when dry, but in the water the shiny coat disappears and you can't tell that there is epoxy on there. It dries hard as a rock, seals everything in underneath, and is very durable. It's used by public aquariums and museums. So, I ordered a quart of it, and it should arrive in a few days, hopefully in time for the weekend.

I figured that I put so much time and effort into this stuff, that it would be a shame to ruin it. The Drylok is great, but, all it takes is a scrape from some sort of cleaning tool to chip off some foam or Drylok and you have an ugly pink spot. The rock wall background and roots are actually pretty fragile. I'm sure that I could easily chip off the grout, so this epoxy will help the roots too. So, for now, another week, probably.

Blennies Rock!
