Re:Waterchanges and nitrate in broodstock

Adam, my setup isn't much different than yours other than you use UV on broodstock and I don't. Hmmm... Arc, yeah I am pretty sure it is the bioballs causing nitrate, but something has to devour the ammonia...so? I have a small amount of Caulerpa prolifera in one tank, but it died off in the other tanks. There isn't much light over the tanks, just a single T8. Should be enough for Caulerpa though. I will try adding some Feather Caulerpa.

I have discovered something...! Bottoming siphoning is the answer! I started bottom siphoning my broodstock tanks in the middle of the week (waterchanges on Sundays), and this seems to have made a big difference for me. The bottom siphoning only removes about 4% of the water volume (less than one 5-gallon pail), and only takes me 10 minutes. I'm currently sitting around 30 ppm, and I didn't do the Sunday waterchange a few days ago. Yippee!

Do you have decent life in your broodstock? I have tons of pods and hundreds if not thousands of worms under the rocks and tiles.

Lots of pods, but I haven't seen any bristleworms or anything like that. It could be that once the system is more established it will be able to deal with nutrients better...that's possibly what I'm seeing now. I would have to look back in my records, but I think I set up the system in Nov or Dec...?? So many variables...hard to be sure of anything. Haha!
