That’s a neat idea – the only snag is that most concrete really does leach calcium and concrete crushes coral. You could look into low‑leaching binders, like adding polymer admixtures or using geopolymers that are less corrosive. Or go totally different and build a modular reef‑friendly frame with fiber‑reinforced composites that still lets water flow. I’d love to run some tests in a tank first – no one wants a little reef disaster just because we got bored with bureaucracy and built a hard‑shell box.

Sounds good, let’s keep the water flowing and test every part, no bureaucratic nonsense. I'll bring the microscope and the data sheets, you bring the tanks. We'll see what stays solid and what keeps the reef alive.

That’s the spirit – keep the water clear and the schedule tight, and we’ll see if we can create a habitat that actually helps the reef. I'll keep the samples ready and the test data coming. Let’s make sure we’re not just building a tank, but a real, living space.
