N03

Would dosing vodka help if the N03 is actually that high?

 

[heath]

not sure if it would help but at this point you really have nothing to loose...

Unfortunately not.

No form of carbon dosing (bio-pellets, bio-cubes, vinegar, sugar, vodka, nopox) will lower nitrates when phosphates are not present.

I think that is incorrect. Even if you are measuring 0 phosphates, you still have them in your system if you are feeding. So maybe at absolute 0 that may be true, but that is essentially impossible. Available phosphates are very likely being removed by your gfo. Carbon dosing most certainly will eliminate nitrates in your tank IMO. Will it be enough though. You may need to feed less etc to find out where they are coming from to at least prevent further build up in the short term. BP if implemented need to be brought on slowly.

Yeah i run gfo an have alot of nuissance algae growing. Theres definately p04 in my system. If i turn gfo off i see it climb.

So maybe start with a couple larger water changes and start slowly bringing BPs on?

To most effectively drop the concentration do a single water change that is as large as you possibly can do in one shot...borrow a tank or barrel if necessary to make as much new water as you can and carefully match params especially the Alk. Carbon dosing is a longer term solution but your corals need more immediate water quality help not system changes...they should be more gradual...IMO

These are not corals that have been adapted to high nutrients long term which would require more gradual changing of nutrient levels.

Agreed. Large WC will help. 50% WC, in essence, will bring down your N by 50%. Still leaving it high enough to not hurt your corals. Any carbon dosing can take weeks to affect your tank

not sure if this relevant to your issues but, as most know I have battled algae, PO4 in my tanks due to my rock... are you running filter socks to catch the debris , while you are treating the tank.. I wasn't for a bit, my stupid mistake and I was treating and putting it right back into the tank..just a thought...

 

[jroovers]

I agree with Torx and Adinfinitum. Also, I'd back off on your feedings of frozen for the time being, stick to pellets and flake (somewhat sparingly, you don't want to starve your fish, but you don't need to exacerbate your nitrate problem).

The biggest change i can do is 30gals. Will that be large enough?

NitraGuard titanium works on high nitrates even if your pox is low.
2 years ago i had nitrates over 60 ppm, pox 0.15 ppm (way lower than the 1:16 ratio).
Put in 1 liter of nitraguard titanium with bomb method in the sump. NO3 started droping after about a week and in 3 weeks I had NO3 under 5 ppm. Lesson learned, I should not let it drop so quickly. Lost 3 beautifull, large euphilias. They were happy in high nitrates, so the sudden drop must have killed them.
My tank is 125 g with 30 g sump. I have 26 fish (2 tangs are about 5-6" -blue and salefin) and I feed a lot some pelets in the morning 3 cubes of frozen at noon and 2 cubes in the evening. Still using nitraguard in a diy reactor, but just a few cubes in it. NO3 now is between 5 and 10.

A 30 gal WC in a 135 (iirc) is only 20%. 20% will only lower 50ppm to 40ppm. Seeing that your range could be up to 100 ppm, that would only bring it down to 80ppm. Slow and steady works, but just have to do more.

Only shitty thing is i leave sunday night and dont get back until thursday morning. So im hoping to do a w.c and get the BPs rolling before then.

why can you only do 30g water change, because of the sump...

I'm sure that's all the Rodi he has on hand

[heath]

thanks, tried to figure that one out...

 

[heath]

is there some coalition between the size of the tank to the optimal size of the sump... I always thought that the idea of a sump was to basically wash/clean your tank water.. just wondering if maybe the sump is too small.. I run a 55 gal on the 125 (wish I could bigger) and I am upgrading the 75 to a 55 gal sump...or is my thinking out in left field..

 

[Sewerat]

Bigger is always better.

The solution to pollution is dilution.

 

[reeferkeeper420]

Because my mixing container only holds 32 gals lol. I could do 60 because of th other container but then id have nothing to empty the water in.
