Apologies for the delay in updates - been busy on several fronts - but here's the history:
Saturday afternoon 9/17/11 - introduced a small 2.25" orange shoulder tang for deejeff442. Acclimated him and introduced to the tank at 1.024/78.5deg f/8.1ph. left lights off for the rest of the day Sat. Fed them a little - as there;s ambient sunlight till dark in the bathroom the qtine tank is setup in.
Sunday morning, 9/18 - lights on at 0800. fed fishes and ensured everyone was eating. By 0900 all food was gone. I premixed ~15gal straight RO/DI (SG 1.000) with buffer to 8.1ph, and began Hypo by removing ~10% tank volume and replacing with buffered (8.1pH) rodi. This brought SG down to 1.021. Fed fish again couple hours later. By 5pm, removed another 10% tank volume (2 gal) and again replaced with premix ro/di. This brought Sg down to 1.018. Lights out.
Monday morning 9/19 - lights on at 0800. fed fish and again ensured all were eating. At 0900 after food was gone, again removed about 10% tank volume by vaccuming bottom of tank to remove poop, and replaced with same premixed water (8.1 pH and no salt added). SG then was about 1.014. Fed fish at noon, and at 5ish pm, again removed amother ~10%, replacing with the premix. SG now 1.011. fed fish, lights off an hour later.
Tuesday morn - same basic schedule as monday - feed/vacuum/replace water with premix - SG now at 1.008, PH 8.0, Temp 78.3. Other water parameters:
Nitrites - under .02 ppm
Free Ammonia - 0 ppm
Nitrates - under 1.0 ppm
Just now, since we're at 1.008 sg - I premixed 30gallons of new water at 1.008 and buffered up to 8.1pH. Tomorrow and about every other day (3 max) we'll be doing 25-50% waterchanges while really vacumming all the detritus... On a lighter stocked qtine tank - it'd be possible to go 3-5 days between waterchanges, but we have a light biocapacity, and heavy bioload - so probably everyother day we'll be doing a w/c, keeping lots of premix on hand, and in 5 weeks, we'll begin comming back up with SG - as long as fish are clear of parasites.
Here's the orange shoulder tang for deejeff442:
I cannot get a close up yet - he's still terrified of people, but he is spending more time each day outside of the cups/pvc. The rest have already learned that everytime I'm in there next to the tank, it's feeding time! and everyone eats like a hog. I suspect the tang will be much less stressed when I'm next to the tank in another 10 days/2 weeks.
