Central filtration would be nice but not really feasible in my room. That works with custom tank walls but I'm using tanks picked up cheap from craigslist.com scattered around the room. Plumbing a central system would be very difficult. I've focused on HOB
's so maint is easy enough and I can add chem filtration to a single tank if needed.
I wanted to point out that on my largest 225 gal
tank the video shows my DIY HOB
system that so far is working great. It holds 14 gal
and is fed by 2 powerheads each rated at 300 gph
. It's full of lava rock and house plants that feed (happily) on the water to remove nitrates. It's sort of like a pond bog filter. I used stuff/junk laying around so I have maybe $15 in it. The tank was free too. It's from a school display that was running back in the '80s. I had to re-seal and build a frame (with more junk I had) but so far it's working great. BTY - GE SilconeI sealant works great. Used it in several tanks with no problems.
It's getting chilly here lately but the heat system is doing it's job nicely so the tanks are staying in the mid to upper 70's with no tank heaters. I'm hoping this proves to save in overall operation costs. This whole project was based on a tight budget as I've been laid off since January...
