#2D-3D stacked high density Algae Turf Scrubber: Start of project: Introduction Since the ATS will be designed to be high density, the material should be of thin thickness to allow for high stacking volume. Another issue that users will probably faced with high density ATS would be cleaning during maintenance. As such, scrubbing off the algae from the media may be infeasible. A thin, disposable material of low cost would be ideal. Materials & Methods A food grade polymer mesh with perforations is chosen as a starting material as it is disposable, doesn't not leak significant amounts of chemicals, easily available and affordable. Ease of availability is advantageous to DIY-ers. The material, as shown in the first picture, is rough on one side and smooth on the other, hence it is thermally spot fused to provide 2 sides of rough surface. This method of attachement is more superior than stapling as it is more suitable to marine conditions and no additional material is used, which will not increase the chance of additional chemical leakage into the water. A clear nylon fishing line is punctured on the top and bottom edge of the mesh to provide structural strength to the mesh, allowing it to remain flat. This also serves as a means to support and hold the mesh in place. Lead strip is used to weigh down the mesh. An Eheim air diffuser is used, driven by a Hi-blow baby air pump. The mesh is placed above the diffuser, along the flow of the air bubbles, as shown in the second picture. The bubbles will direct oxygen and nutrient rich water along the surface of the mesh, providing a suitable condition for the growth of algae. The third picture shows a close up of the mesh from the surface of the water. Both surfaces of the mesh are inoculated with small amounts of green algae. The reason for this is to determine if the mesh surface is suitable for the attachement of algae. And since the tank used is a freshwater planted tank with 2 ottos, this will provide the algae a higher chance of populating the mesh faster than the rate of ottos consuming them. Seachem Excel and Flourish are being dosed at 25% higher than recommended at a rate of twice weekly. The 4th picture shows the ottos. The mesh will be subjected to a 8-12 hours variable lighting (blue and white 12W led).

thanks to bros who pmed me about tank deals in market, really appreciate it. I am looking for 2ft braceless all sides crystal glass tank

Looking for Teco TR 5, TR10, TR15, Arctica nano, mini, 1/10 or 1/5

mp10, mangrove box and tank!

1 more project to the list: Using k1 filter media as substrate for ATS; assessing the suitability of k1 surface for algae growth and the feasibility of k1 moving bed filter as a partial self-cleaning ATS (using sponge filter media to filter output water from ATS) Anyone willing to spare some k1? haha Extension from 1 previously listed project: Usage of ascorbic acid in replacement of co2 in calcium reactor for the supplementation of calcium and buffered, stabilised vitamin C

Have you tried nsw b4? If yes, is it better than premix?

Erm, sorry to ask, where can i buy replacement resins for that?

You know the cost?

what brand?

no of post not important, haha. bell, what salt mix are you going to use? or are you one of the fortunate people who can just drop a return pump down from their house to get unlimited seawater?

haha, impossible. my table cannot support the weight

Teco not as good as Arctica? Bro, 1/5 seems too large for my tank, sorry

Thanks, I need quite a few, =)

suddenly realised kept talking about equipment and totally forgotten about the water. after some reading, decided on aquavitro salinity and its range of additives.

willling to take aqua lifter if it becomes available

Thanks

kaykay, output should not be restricted. place the sponge along the flow, making sure there's no restrictions

smsed you

you can add a sponge at the outlet too, helps to make microbubbles into bubbles.

me too

Hi, Any comment on aqua lifter and where can I purchase them?

looking for aqua lifters with prefilters

nicely done

yup, from what I see, better to confirm, haha

biopellets can be unstable, population can crash rather rapidly. if you go to the marine equipment section, you will see a sulphur denitrator 18 years and going sticky. sulphur in sandbed has no difference compared to sulphur reactors. the sand bed just provides an anaerobic condition for the sulphur beads. no reactor = save money, electricity and less heat, bell, can pass me your tank maker's contact? trying to get a tank done. i am planning a 3 months cycling period, need to rush the tank,
