Re: Liza's 20L Nano Tank
OK, so I've never ever dedicated so much thought and DIY skills-practice to any tank component as to aeration lately.
Looks like I'm stuck here:
There is no technology in the tank except the glass in- and outflow. This obviously means I have to introduce air through the external filter hosing. Let me tell you what my problems are:
1. Air pumps are too noisy. I tried Tetra, Ferplast, Schego (on timer at night). The later is the best of all, but still too noisy for my daughter sleeping right next to the tank. An 50 lph Ferplast would be ok soundwise, but the filter pressure is too strong for this size of an airpump and no bubbles enter through the Tee on the filter hose.
2. The AquaMedic 12/16 and 4/6 Tee is garbage. The 4/6 end is made of soft plastic, I already broke 2 Tees in the process of dealing with hose changes - so I gave this up. Plus it produces bigger bubbles that make too much noise when entering into the tank and coming to the surface.
3. Tried a normal 12/16 Tee with an airstone glued to one end - same result: bubbles too big - too much noise.
4. I tried many products and there is no way to use an air-pump with a CO2 diffuser (internal or external of any kind) to produce smaller bubbles. They are obviously designed for bigger pressures.
Silence is the most important issue here.
Any ideas? Any products you recommend (like an external O2 reactor)?
