Thanks guys, simple idea really, if you try to make some, it works better if all the hoses are tied together at the base. If you try individually sticking them in, they tend to float back out before the concrete cures. One and two foot lenghts if you care. Hindsight says I should have made and umbrella type thing (securing several different lenghts in one trunk, to give it some heighth).
TJ, I now have: 1200 initially stocked BG, 300 RES, 150 initially stocked CC, 50 lbs initially stocked FHM, and the 10 lbs RRM, soon to be 360 LMB, 4 know crawfish. That is if there weren't some oddball undesirables in the mix. What do you think?
