Comment, yes.Ok- planning out my big water change for nitrate reduction post cycle.
I currently have 165 g in the tank. It’s at 80ppm. The following calcs assume 80ppm as the starting number, but they might well be 132ppm for all I really know (API master test kit).
Plan is to move a 55gal drum upstairs next to tank, rodi fill it, add salt, then remove 100 gallon from DT. Add back the 100 gallons of nsw over 2 batches. This first change will put nitrates at 31ppm. I’ll know at this point where my numbers are at in reality.
Then repeat, for a final nitrate ppm of 13ppm.
At this point, I bring the 90 gallons of nsw sump water online — this will dilute the DT to 8ppm nitrate.
Then regular 15 % changes ongoing to keep things stable.
No livestock currently- but I’ll be adding QT’d fish in 6 weeks and the CUC graduate QT on December 18.
A bunch of the live rock will be exposed for however long it takes to drain and pump 50 gallons back in— around 20 minutes. No problem, right?
Reason for the quick drop in nitrates / aggressive water change is that wife is getting bored looking at rocks and saw some purple urchins at petco. She remembered I told her they are one of the few things that don’t need QT . I told her they’ll need nitrates <10 ppm and a bunch of nori to munch on and she said ‘yes’. Confused since it wasn’t a yes/no kinda statement, but here we are.
Any comments? Should I not be so aggressive and do smaller changes? Talk the wife out of the urchins and use the 6 week fish QT to get things squared away in the DT ?
Cheers
Comment, yes.
Lol
Sounds like a good plan.
Dude- too late!!
Where were you yesterday?
Lol
Love the build! Make any progress diluting things down and bringing the sump online over the weekend?
This is such a great build man.
No clue about the egg laying in QT, my pair of black Os are still really young and we haven’t had the birds and bees talk, yet.
I can't speak to clowns laying eggs in QT under copper or anything like that, but I've had clowns get funky about a week after being added to a tank. Tank was thrown together quickly when a family friend was moving and needed his wife's reef torn down and shipped to them in a different state. Parameters were not perfect and the tank ran hotter than I'd like since it was in my garage for over a month during the summer. It may have helped that it was a 150g stock tank with a fairly low load of fish and a decent live amount of live rock, but those clowns had a clutch of eggs laid at about 8-10 days.
