well, here's today's update.
after siuphoning the sandbed a few times and churining up clouds of dust from the substrate, i decided tofloow the old maxim of divide and conquer. so i took to scoopfulls of sand and put them in a bucket. there i filled it with a some water and kneaded the sand, trying to work out the dust. i would work the sand for amybe a few minutes and then pitch the water and dust, then fill the bucket and repeat. ten rinses later the sand was still giving me the same dust clouds as before. so i just thought f*** this and pitched the sand out. i managed to save most of the laterite using a some cheesescloth as buckets ofm sand were emptied. i went to the lfs and bought 25 pounds of "aztec gold" color aquarium gravel made by dowell. i then took some water from the other twenty gallon tank, about 8-10 gallons worth,a nd put it in with some substrate from the ten gallon tank this was supposed to update. with the sponge filter running and a filter that was fully seeded before on the previous tank running, the cycle should be next to nothing. i added a common pleco, the tilapia, 1 filament barb, and 1 small red tail shark. they love the long swimming space!
