Cut out the acrylic panels for the filter the other day. Just gotta sand them down a bit and then everything is ready to ...
Acrylic filter plates are sanded down, and the plumbing is all glued together. Just need to add holes for the inlet and outlet of the filter and I'm all ready to assemble. I did change plans slightly for the filter layout. Instead of three chambers there will only be two. There just wasn't space for three. So I will have bio and mechanical in the same chamber, one on top of the other. This should make it a little easier to fiddle around in the sump if I need to and makes assembly a bit simpler. Hopefully more pics tomorrow!
Almost done with the filter. I drilled holes for intake and return. Trimmed the middle two plates so water can flow between chambers. Sanded corners so they fit nicely against the acrylic seams. I am currently installing the filter and am posting while some of the silicone sets.
I switched back to the three chamber filter. I needed the extra partition in there in order to have an overflow to set the water level in the main tank. Now I have all the media in the first chamber. The heater will be in the second chamber instead of in the sump, this makes sure it always stays submerged no matter what. The third chamber just hides the pump and CO2 reactor, this should be the only place in the tank with a variable water level. If any of the pictures look out of order it is just because I am test fitting. Also, if they look upside down, I had the top of the aquarium facing me while I worked and had all the parts arrayed that way too. Some of the pictures are hard to see, all the parts are black because I wanted to hide them lol.
let it set over night and got it all filled up for testing today. Return and reactor work great as expected. However the water level in the main tank was getting really high before the water would flow through the filter properly. I fiddled with it for a while, changed things back and forth. Ultimately I ended up figuring out that the pre filter and it's half inch tube were just too great a resistance for the small amount of water level drop between chambers. I knew before hand that using the same size pipe for inlet and outlet wasn't the best idea, especially since the inlet was gravity fed, but I just figured my flowrate was so low it wouldn't matter. I think using 3/4 inch pvc instead of 1/2 and a coarser pre filter would work well, but I don't really want to take it apart. For now I have just twisted off the pipe for the intake so I just have a hole in the plate as the inlet. I'm kinda annoyed with this since the fish/shrimp can just swim in/out, but the flow rate is slow low they should be able to just swim right out. If it gives me any trouble I'll make some modifications, otherwise I'll just leave it alone. It's all packed up for my move to school so I'll take more pictures once I get there.
I've been thinking about stocking again, and I really want feedback. Current stock list is:
8 Corydorus Habrosus
8 Ember Tetra
Malaysian Trumpet Snail
3-5 Amano Shrimp
Tank water volume is 11 gallons. Does this seem reasonable? I'll probably omit both the otos and the amano shrimp. I'm just really concerned about being overstocked.
