Good advice, thank you...... I've also been reading through posts on other boards here and have gotten more ideas to follow, like collecting sand and gravel to start out with and if I do that,what would it hurt to bring back water too? Should definately cut down on the time it will take to cycle. Any ideas of how long it might take to cycle if I do bring in gathered sand/gravel and some water? I am not set up to be transporting a lot of water as I would have to do it all by hand, pail by pail, so what do you think would be enough to get everything started off in the right direction? How much filtration should I aim for?
