Hey!
Well, I got married. We were gone for 4.5 days and I was nervous about leaving things for so long. It seems my concern was justified a bit. I had a quiet explosion of brown fuzz that is slowly choking my HC carpet. It seems to be struggling to grow but - surprisingly enough - succeeding anyhow. Everything else - well, see for your self (I also added three stems of b. aubertii and more b. japonica to fill in the space. I may have to thin out the aubertii):
Here’s a fat little oto taking a break from snacking on the fuzz:
The big chunky hunk of machinery in the dead center is my power head reactor. Here’s the story with that:
I’m assuming since my CO2 level is consistent with when I left, the lights were on a 5 hour + 3 hour time cycle with a 3 hour hiatus, my nitrates were at about 7ppm, PO4 was at 0, and my canister filter flow rate was significantly reduced, the algae was caused by a combination of PO4/micros shortage, (also indicated by the paleness of the new growth in the plants) and lack of flow on the bottom of the tank. I cleaned the filters the day before I left, so I wasn’t sure what to do there. The shortages I expected, and resumed ‘ferts the day after I returned at previous levels. The algae continued to get worse, despite my resumption of the ‘ferts, and observation showed I was getting no circulation at the bottom.
So, I decided at least until I can figure out some better plumbing, I need to get a cheapo big-box power head to help out. I installed the monster. I think it’s a little big. Plus, it’s GODAWFUL unsightly.
Recently, I had rigged my CO2 tube to a tiny ceramic diffuser that is shaped like an air pump diffuser and crammed it into my Jebo intake strainer to use the Jebo as a reactor. That seemed to work all right before, but when I rearranged the spray bars it totally changed the circulation in the tank. This meant that only the left side was getting CO2. I had to pull it. After a couple hours of research on APC and other forums, websites, and such, I decided to rig up this temporary system:
The clear tube is just undergravel filter tubing cut to length with an X-acto razor saw. I drilled a 1/8” hole in the side of it to fit the ceramic diffuser, and then assembled the works. The diffuser creates tiny bubbles, and the power head makes those tiny bubbles microscopic. Keep in mind that my water is crystal clear - except for bubbles.
Here is a link to a video of the bubbles. I don’t think it’s clear enough to appreciate the cloud that is spewing forth from my power head, but It’s pretty phenomenal - at the expense of looking about as klunky as anything could.

So, here’s my issue: Now what? I don’t like the klunky mess the power head creates, but I do want to get as much CO2 in there as possible. I also really want to clean up the filter plumbing. I want a single, full-length spray bar in clear tubing across the top of the tank. I also think that I can get rid of the Jebo if I can increase the flow from the XP3. I have an idea that I have been researching for precedent, but there is none. I think it could work, but I’m no engineer, nor am I a plumber, and I’m a little concerned about the physics.
What are the flow solutions you have tried for a big tank like this? I’m looking for the goose with the golden egg, like everyone else: I want the components invisible or outside of the tank, and I want one inlet and one outlet. I’m tired of the mix-and-match-glass-bucket-full-of-multicolored-pipes. Oh yeah, and I want it free.
