Speaking of urchins, its probably unrelated to the pellets but my 5 year old long-spine is in the corner losing its spines. There seems to be less algae on the front glass and the skimmers are starting to produce a little more.

Ok, the skimmage smell is so bad. My wife can smell it 10 feets away when i empty the cup

My nitrate reading still not dropping with api test kit after 5 days running. I do see lots of mulms like Tony described

coleus, I believe they were using a pinpoint nitrate monitor to watch. I believe the test kit's were rather inconclusive.

Is anybody monitoring their ORP while using this product? My ozone generator has been offline for some time now and the ORP was hovering around 380 mark +/- 20 mv. I started with the NP pellets and my ORP has steadily dropped to 260 mv. Not sure what it is today but has anybody else noted their ORP levels dropping?

Sorry no, I haven't done so, nor do I have any way to.

I haven't even tested nitrates, etc... Just watching to positive affects to algae depletion, water clearness and overall color happiness

my orp (Profilux ORP probe connected to controller) was hovering around 410 prior to the pellets and now it is still hovering around 410. So I haven't noticed any change. Lots of people were reporting tonnes of mulm from their pellets, and although I had some, It did not get out of control. I think Tony said that when he shook his pellets his entire tank went snowy ? All that mulm could cause your ORP to drop maybe ? So if an ORP drop is caused by the pellets then either the mulm isn't being consumed or skimmed out fast enough maybe?

ORP in my tank did not change at all, it was 350 and still 350 after a month or so of using the pellets.

( side note: i have a lot of air going through an air driven skimmer in addition to Deltec 600 skimmer )

My ORP hasn't really changed still at 340. I've got a lot of flow that's really churning 2 litres of pellets and haven't noticed any mulm yet.

Yeah, now that I've been able to resolve the clumping issues I don't have the mulm buildup anymore. I just had a tiny bit too much pellets for the phosban reactor, that's why I'm telling people now they're better off running fewer pellets than the recommendation because it will still work fine, just run out sooner, but will work better because of the increased mulm shedding.

Well I am up and running with the N/P pellets. One of my sleepless night projects. Did testing to phosphate 1.0mg/l and nitrate 25mg/l. Elos test kits. I can tell the pellets are working by the smell burping out of my skimmer. We will see how it works and that I get practice using my test kit.:biggrin:
