This is really nice. I have two planted hobs, but unfortunately no room to add something like this because the tank is too narrow. Very cool though. I'll definitely keep in in mind if I do one on a different tank.
Nice...what are your water parameters like, specifically hardness, alkanity, nitrates, temp and pH.
Been pretty steady:
GH about 80 - 100 ppm (very soft water mineralized with fluval shrimp supplement. Stopped using Seachem Equilibrium on this little tank)
KH about 40 ppm or less
nitrates about 5 ppm (comes out of the tap that way)
temp 72 to 75. No heater, in an office building.
PH 6.5 to 6.8 (come out of the tap that way)
Thanks everybody! Just building on the ideas of others
I have to trim the HOB plants more than the ones in the tank now, really been growing well. What ever kind of red-ish stem (ludwigia?) that is LOVES being emerged and is going nuts, so does the "clover vine" (hydrocotyle japan i think).
Every once in a while I stick my finger into the spillway part ot be sure water is still flowing through and over, cause i can't see it anymore
Using a coarse sponge as the growing media at the top of the HOB is working and showing huge growth. Here is a small piece that shows the plants putting a root system down in the sponge with no problem:
