Yikes! Nitrates too high

Recommended Posts

Wow, looks like my old Elos nitrate test kit must have expired a while ago. Just got new Red Sea pro kit (very nice btw), and I'm looking at 16 ppm! Had to use the high range adjustment! Looks like I'll be starting some sort of carbon dosing. What a pain; I've been falsely thinking all this time that my refugium was magic

Be careful dosing too much carbon sources. Been there and now I'm dosing nitrate to get a reading above 0 :(

 

Shoot for 2-10 and everything will be happy. Especially if you have a mixed reef, my lps have been pissed with no nitrates.

That's exactly what I'm thinking. 3-4 should be high enough for my fuge to stay alive. I think I'm going to try the Red Sea NO3:PO4-X product.

I find when carbon dosing I have to spot feed my LPS. I can't seem to find a middle ground between carbon dosing and not spot feeding IME. I do also feed several times a day so there is food present more often. Then again if I wasn't feeding several times a day, maybe I wouldn't need to carbon dose...

I'd be curious what is in that and if it is actually any better then other carbon sources like sugar, vinegar, or vodka. $15 bucks isn't bad, but if your paying $15 for 500mL of some vinegar with sugar added to it that would kinda suck. Not saying that is what Red Sea NO3:PO4-X is because I don't know, but vinegar, sugar, and vodka all seem to do the same thing. If you do decide to go with carbon dosing, make sure to remove your GFO. It will make things much more effective IME.

Yeah I have been feeding the tank a lot lately. I usually don't spot feed as my fish go ape when food starts flying around. Don't want them nipping at the LPS for food scraps. I try to early morning and late night if I can.

 

I would also suggest trying vinegar or vodka dosing. It's easy, cheap and proven. At least do your research before trying the Red Sea product. Good luck!

Skimmer, water movement, bacteria, fish population, feeding... I never really worry about NO3. If you don't have a lot of fish and you don't feed a lot maybe you can try add some BioSpira bacteria; they keep your NO3 really low.

Any updates? Did you carbon dose?

I'm a week into the Red Sea N03-X product. Dosing 11 ml/day with my handy dandy BRS doser. Reading about it, it is something between vodka, vinegar, and sugar. Read about lots of great long term results with it, and it's really not that much more than a bottle of vodka. Plus, I'm less likely to drink it :-)

Probably to soon to see any real results yet? I'm still curious so I gotta ask, how's it workin [emoji2].

 

My wife dipped into my fish tank vodka back when I used Kettle One. Since I switched to Gilbert's she drinks her own. It does save you from going into the liquor store and asking for the biggest cheapest bottle of vodka they have and the looks that come with it [emoji6]

 

Please do keep is updated

Well almost one week out and taking my first measurements. Nitrates aren't registering on test kit, even at low range. I've cut back from recommended 11 ml/day to 3 ml/day. I expected it to take at least a couple weeks to start dropping. Tank looks completely unphased though luckily. More next week!

 That's great Bill. Looks like you found your answer. Let us know if things change.

A while back I also used the Red Sea NOPOX, when my nitrates and phosphates started getting high. That stuff IS magic in a bottle! Works fast and works good. I think my spike was caused by adding uncured rock and feeding too much. Since using NOPOX the rock has cured in the tank and I've cut back on feeding, my nitrates are undetectable and phosphates are very low. Took maybe two weeks of use to stabilize the tank. Haven't had to dose it anymore after the two week "bio rebuild".

Huh, so in your experience you didn't have to keep dosing... crazy.

 

With Carbon I have to dose everyday, for years now. If I take a break the levels rise again. 

 

I think you guys are talking me into a new product.

That's how it worked for me. Before the rock was added I had some nitrate and phosphate but not much, probably cause I like fat fish and thought more food equals fatter and healthier fish. I think the rock caused the spike, I controlled the spike with the NOPOX. Once the rock was cured levels went back to normal and didn't need to dose anymore. Since then I have cut back on feeding and nitrates are undetectable and phosphates are low, with API test.

I'm dosing 10 seconds a day with my 1.1 ml/min pump, which is too small for me to figure out right now. I'm still showing zero nitrates. Tank is looking good though. I've noticed s couple things though. My fuge has no more cyano slime growing on top, and it has an explosion of small brittlestars all over in the algae.
