Things are running just bubbly so far on this project and I�ve made some changes to operational procedures with more changes on the way.
When the project started, I didn�t expect or plan to use the high speed jet recirculation or forced air jet aeration capabilities of the spa�just use it as a holding tank and water heater. As fish wastes have been generated, some have settled into the various irregular shapes of the spa/hot tub which is made for comfortable seating of humans. This is difficult to remove with just one main recirculating pump. I tried a fine mesh pool skimmer with good results but it still leaves a lot of fine particles in the water. So, turn on the high speed jets and high pressure air system and see what happens�it is still an experiment, after all.
Well, the results really surprised me. The high speed jets coupled with high pressure air completely stirs up the wastes to where the entire system can be completely filtered in about 10 minutes. I was at first fearful of how the fish would react to this procedure�but you know what, they actually seem to enjoy it much like we would in taking a dip in the hot tub. No kidding, ROTFL but they really do. If and when it becomes necessary to run this procedure longer, it may still have adverse affects of the fish but so far, they line up every morning for the daily spa.
Next up, I�m working on some automation methods for the feeding and water quality processes.
p.s. note to moderators...this thread should probably be moved to the raising forage and bait category. Thanks.
