I'll take the fishes. PM sent.

I need to convert my freshwater tank to a saltwater tank. So, I need to give away a current tank resident, a pond fish 6" long (attached pic). Anyone interested? Pick-up in Alexandria, 22304. Binh

That will be good tests. Thanks.

Thanks for your interest in the filter. I'll contact you when I have the prototypes for testing. Binh

Filtering capability: The screens you see in the video have a total area of about 200 square inches (to compare, the Turbo L4 algae scrubber has about 100 sq inches rated for 4 cubes/day and it's sold for more than $500; the SURF4 has a similar filtering capacity and price.) And if you want to increase the filtering capacity, you can simply daisy chain another filter next to the first for a doubled capacity with just a slightly increased pump power needed to make up for the increased friction. There are no extensive tests yet. The prototypes for beta testers will come out in a month or so. Thanks Binh

Thanks a lot for your vote. Binh

Thanks a lot, s2nhle, for your vote. The price with manual & 3D printing production is probably under $300 (compared to the $400+ price tag of other algae scrubbers currently on the market with less filtering capacity). When it's mass produced with injection molding, it will be much cheaper. Thanks Binh

Great. Thanks.

Thank you so much for your vote. Binh

Hello Everyone, My team and I are developing a new type of algae scrubber called AlgaeJet. It's compact, efficient, quiet, scalable, and cost-effective. We are entering it in the UPS Store contest. Please check it out and vote for us here to win: http://theupsstorepi...est/1/entry/183 Thank you very much, Binh

Hello Everyone, Two years ago, I came up with a new design for the algae scrubber that has a potential to provide much better efficiency than that of existing designs (e.g., waterfall, upflow) while in a very compact and easy to use form factor like a canister filter (i.e., silent, splash-proof, low-maintenance) that can be used without a sump. I created a proof of concept and it worked very well. Since then, I was able to find an investor to create a startup and we filed an international non-provisional patent application. We also got a couple of mechanical engineers to join the venture and help create a complete 3D model of the design. We are now trying to produce a few tens of prototypes using 3D printers to give to beta testers for feedback before we proceed to finalize the design for molding and mass-production. For the production of these prototypes, we are now looking for a contractor in the Washington DC area to help with the preparing and assembling of parts, including some simple painting, gluing, cutting, etc. for each prototype. You may also get to work with the 3D printers. Initially, we will pay you an hourly wage. If we work well together, you are welcome to join the venture for shares since we will definitely need more help to execute the business later on. If you are a long-time hobbyist who has experience in DIY aquarium-related projects and is interested in this work, please contact me at arintel@gmail.com. Or if you know somebody who is, please refer them to this post. Thank you very much, Binh

Hello Everyone, Every time I stopped and restarted the return pump, there was some white/translucent stuff that looks like snow flakes coming out of the hose into the display tank. It grew on the inside of the hose and at high-flow areas like on the glass right where water comes out of the return line. The white stuff was growing very fast recently and it would significantly reduce the flow rate of the return line just over a few hours, day or night (which seems to indicate it's not related to lighting). However, interestingly, for the last few days, when I used PhosGuard to reduce the phosphate level from over 5 ppm down close to 0 and used CopperSafe to treat ich, I noticed that the white stuff has been reduced significantly, too. Also, the skimmate from my protein skimmer turned from yellow (before) to almost black now with lots of bubbles in the collection cup that do not collapse to be liquid. I have the following questions: 1. What exactly is the white stuff? 2. Was it reduced by CopperSafe or by the low level of phosphate? 3. Was the black skimmate a result of dead ich or the dead white stuff? Thanks a lot, Arintel
