Zero nitrates after prazipro treatment?

[ajiisss]

Any one observed zero or low nitrate readings after prazipro treatment? I might be wrong but just curious

 

[Spare time]

I haven't, but something in it (the solvent?) can promote bacterial blooms which in turn may lower nitrate.

Interesting thanks

I've heard of this before in threads on R2R years ago.

I almost revived a thread from four years ago for this, so this one’s not even zombie status yet.

I dosed Prazipro about 10 days ago, ended up not doing a second doseing, as I it ended up not being the treatment route I need to take, was more of a last ditch effort for a sick wrasse I didn’t wanna pull all the rocks out to catch.

Yesterday I noticed one set of my Zoas that have looked great since putting them in 7 or so weeks ago (new tank, just got wet on Labor Day) aren’t just all closed up, but look like they’re about to disappear. Saw it late last night, and was only thing lookin off.

When checkin Params my nitrates read 0.1! The lowest I’ve tested put my system has been 7.

7 days after dosing Prazipro, I did a about a 25% water change, give or take a few percent I didn’t measure the excess I took from display, wish I would’ve, this was biggest water change to date so I was worried I wouldn’t have enough mixed when time to fill. I resumed my GAC reactor, as well as turned the UV lamp back on.
Suppose it’s also worth mentioning, I’ve been struggling to keep PH above 7.7, although since GAC brought back on, has slowly been creeping to higher highs for day, but this is known constraints with Prazipro from what I saw.

Prazipro can absolutely drop your nitrates. I was doing an in tank treatment on my reef tank of the liquid prazipro. Tank was about 6 months old, but was an upgrade from a previous tank using all the old rock and coral with some new rock. I was going to do 3 doses separated by 1 week each, but I stopped after the second dose because my nitrates cratered. They didn’t hit zero but they would have if I had done the third dose. Two interesting things: first, the first dose did nothing. I guess it takes some time to ramp up. Second, it only took 1-2 weeks after I stopped dosing for the nitrates to jump exactly to where they were before. I guess the bacteria feeding on the extra stuff from the prazipro all died and released the nitrate back into the water.

This graph is a few months of data and you can see how quickly it dropped during the dosing and then how quickly it came back.

I did an experiment again and it indeed drop to zero from 15ppm.i think the prazipro is causing a bacterial bloom

So I’ve been carbon dosing to begin with and usually stay between 5-15 PPM. Noticed a sign on a wrasse that’s impossible to catch so I dosed one of my DT with prazipro and all my tests are reading 0 basically. I should probably turn off my doser pump for my NOPOX for a bit I’m assuming? Only dosing 3 ML a day.

Just wait for few days until nitrate climbs to 5ppm . Usually takes 2 weeks

A little late, but I’m experiencing the same thing !

 

[pal98111]

Me too. Nitrates went from 20 to zero overnight

 

[BrettE]

Happened to me too. First dose was on 1/27. That 10ppm measurement is on 1/27 before the praziquantel. Phosphate tells a similar story.

Interesting.. I dosed prazi a few days ago... Nitrates went from 5PPM to 0.1PPM... phosphates went from 0.10 to 0.00...

I thought might be a correlation and searched and found this thread..

Yes, the “inert” organic in it is only inert in a medical sense. It certainly can impact a tank by driving bacteria.

So my nitrates and phosphates still zero.. It's been 4 full days... Will it go up? I started feeding more but still zero. Also put in some reef roids too, didnt move he needle.. both nitrates and phosphates

I’d feed more or dose.

I'm still at zero nitrate and phosphates... was at 5PPM and 0.05ish before... Not sure what to do... I've bee doubling on the feeding and throwing in more benereef and reefroids... having zero impacts..

I wonder if by feeding more, I'm just allowing the new bacteria to live ... should i feed normal and let the new bacteria die off?

One of my acros lost color (from red to green) but still has polyps.. Hope it doesn't die.

Also turned off my skimmer as well.

Dosing seems appropriate, and inexpensive. Cheaper than foods.

Got some sodium nitrate.. just hoping this works and doesnt continue the problem...

What exactly causes the nitrates to go down and stay down?

I don't know if or how it might cause nitrate to stay down, but the carbon dosing effect likely explains some or all of the nitrate decline.
