I've been using these blow-molded conical fermenters as DWC reservoirs to make nute changes quicker and easier. Works great.
The only problem is it's difficult to secure the airstone due to the shape of the walls. The suction cups the airstone provides no doubt work great against a smooth, flat surface like a glass aquarium wall, but they're useless here.
Given the teardrop shape of the thing, I'm sure I could print something to wedge between the smaller diameters above and below the widest section, but I'd prefer not to add some giant contraption for roots to tangle around or that might create stagnant spots.
The airstone becomes buoyant when supplied with air pressure and actually flips upside down. I still get enough aeration, but I'd prefer everything in there stay put. So, weight. I printed this thing, but it's only 45 grams. Maybe its staying better centered will be enough to stop it swimming around; I need to play with it some and see.
I usually try to stick to glass, rock, and food-safe plastic like this TPU, but I'm thinking a chunk of stainless steel to just nuke this problem from orbit. I feel like that might screw up the chemistry of the solution, but I really have no idea. Anybody know? I don't want to go to the trouble of making the things only to discover they mess with my pH or something.
I really like these stones and mean to stick with them one way or another. Any other ideas as to how I might keep them in place?
Thanks.
