High Nitrate removal

[PeterEde]

NoPox needs Phosphates to reduce Nitrates.

I use the below to make up a phosphate additive.

75g Food Grade monosodium phosphate anhydrous (MSP-A) - E 339(i) | eBay Australia

Monosodium Phosphate anhydrous can be used as • Acidulant • Emulsifying Agent • Nutrient • Buffering Agent • Protein Modifier. It is soluble in water with a solubility of 85g in 100ml at 20°C. MSP can be used as a gelling aid by use of its acidulation properties.

I found this product locally with 99% Trisodium phosphate

Trisodium phophates is okay, but I'd be careful about impurities in a cleaning product

Yeah not keen on a hardware store product going in my tank.
Will look for food grade products

I use this to raise phosphate and should be available from any LFS that has planted tanks.

Thanks. I'll look for it or similar today. On my way to LFS shortly

Id say too with either biopellets or nopox to not be surprised by a bacterial bloom or two early on while your system adjusts. Just keep your water oxygenated and it’ll pass on its own.

just cleaned some gunk out of the bio pellet reactor yesterday and it was enough to trigger a bloom for me

Carbon dosing is great at nitrates but not very well at phos removal. Op is looking looking into a sulfur reactor which is similar to carbon dosing and great at removing nitrates but not much for phos. I use a refugium with a COB Led and both nitrates / phos are near 0.

I got a bottle of Triton phosphorous. Added .5ml to 120liter. instant .1 PO4 again.

Let's see how nitrates react with some Phosphate in the system

Keep an eye on it, it can go down fast once the bacterial population builds up.

Yeah expect zero again before dose.

I am a big fan of sulfur denitrification reactors. But they also consume alkalinity... This won't solve your phosphate limitation though.

White sugar works just as good as NOPOX for a carbon source.

I've done this to reduce nitrates from 100ppm down to 0 in 1 week and had to dose P04 as that was limited.

The PO4 supplement used for planted tanks works fine for this purpose.

Obviously, I had no livestock and I'm too lazy to change water.

Hope this helps.

I'm not a fan of sucrose. The couple of times I experimented with it, corals browned up.

25% wc under way
Vacuum sump
Remove some of the cheapbio blocks that just traps detritus

 

[PeterEde]

Nitrates reached 60 yesterday
25% WC and it dropped to 44 as expected.
Continued the day cleaning detritus and just measured. Nitrates at 30. Dropped a further 14 after a few hours.
See what happens with tomorrows test.

There is a part of the story missing for sure. were you consistent with care ? seems to me this took a long time to develop. if that's the case will take a long time to correct. as to skimmer i read that that is a normal reaction to dosing is I believe showing you that the water is being oxygenated. look up the thread. pictures would help. also i had a very bad experience a couple of months ago having to move my tank. i emptied 50% water for weight. i filled it with existing water bad choice tank almost crashed. i just moved it back 2 days ago, and added water very slowly with hose did not stir up bottom. i think maybe you did, and released a lot of bad stuff. you tell me. my remove went perfect

Tank has been pretty stable but for nitrate
