Well I had to figure out a lower cost way to place boo. I found that useing a weed eater with a saw blade worked really good for cutting it down and cutting to the lenghts needed. Then I used a cordless drill with a small drill bit to drill holes just above the bottom joint. Then I used .095 weed eater line to join about 10-12 pecies of boo together with a square knot followed by a 3/8" long piece of 1/4" copper tube squeezed on the line close to the knot to keep the knot from slipping. I then used a sand bag full of sand/dirt to sink it by running a zip tie through the bag just below the tied up top of the sand bag. I already had a 2' piece of 1/4" copper tubing that I cut into 3/8" long pieces so I don't know what it would cost. But I would say that they would be less than $1.00 for each bamboo habitat. So far I have built and dropped 9 of these and they seem to be the best cost effective way that I have found. Hope this will give others ideas and if anyone has more input I am always looking for better cheaper ways.
This is a lot cheaper than a bag of 80# Quickrete which cost $4.70 a bag at Lowes.
Fish habitat: "Build it and they will come".
cost: sand bag= 32 cents each
zip tie = 20 cents each
trimmer line = 20 cents each
-------------
total 72 cents each + ??? copper tube cost which will keep the string knot from slipping loose
