Hello. Guys, I'm going to glue a long 2.8m bio-filter + algae scrubber on top of a PVC aquarium. I have three questions: 1) What to use to glue it so that the glue doesn't release anything harmful into the water later? 2) What to use to attach the acrylic glass to the PVC (on the front part, so I can see what's happening inside). 3) What is the ideal thickness of the coarse coral gravel (4-5 cm) for the dry filter (which will be an extension of the algae scrubber, with a total length of 2.55 meters)? I understand that it's better to calculate based on the organic load, but for now, it's all just on paper. The dimensions of the dry filter itself are: length 25cm, width 20cm, and the height needs to be determined. The aquarium is 300cm x 75cm x 62cm. There will be no sump under the aquarium and no external filters. The equipment includes a Wavebox, flow pumps, UV lamp, and a protein skimmer (which I'm considering using initially, but we'll see). I'm planning a mixed reef, more fish, and LPS. The protein skimmer will be an internal one, AquaC EV-240.
