high nitrates and dosing

So I have high nitrate 60 to 80 ppm and I'm dosing NPK should I stop dosing nitrogen and see if the nitrates drop or cut the dose in half and see where it ends up?

I don't know where I'm going but I'm on my way.

You can stop dosing nitrates; since most people use potassium nitrate for their source of nitrates, stopping dosage might result in a potassium deficiency. This can be remedied through the addition of potassium sulfate.

If it's my tank, I would make changes gradually. Cut the nitrate dosing in half and let things stabilize, measure, adjust accordingly.

if the nitrates are that high, have u check phosphates? they may be the same. its likely due to fish load and feeding. id stary by cutting dosage in half as has already been reccommended.

Re: high nitrates and dosing

From what i have experienced and read/learned. Nitrates that come from potassium nitrate are almost harmless at higher levels, even up to 100-150ppm. Nitrates that are a result of the break down if ammonia and nitrites are a little different and can be toxic at 1-4ppm. I read some of Tom Barrs postings on this recently. In my ordinal tanks my nitrates are usual at or slightly above 40 or 50ppm. I have never had a death from having the level that high.

and you wont, but there is no reason to go that high for 90% of the tanks out there

Ok did a trim and WC the number seem to have stabilize plants look good and the fish look happy except for my ram who is pale again.
But I think it cause my water is neutral and they like it a little acidic.

I don't know where I'm going but I'm on my way.

likely not, i've had rams in alkaline, and acidic water.
clean water and a varied diet will colorize your fish they like warm water too

Nitrate test kits are not always reading correctly, nor are they necessarily being used correctly. To check your nitrate test kit you can try the calibration method described in Calibrating Test Kits - for non-Chemists

Re: high nitrates and dosing

If you keep inverts, the safe range I've heard from prominent vendors here is 10-20 ppm for snails, neos, Amanos, and fan shrimp. More sensitive species require even lower levels.

Tom (plantbrain) reports keeping neos in 45 ppm but with high O2. I couldn't keep Amanos in 40+ ppm under normal circumstances, but I've since gone to the recommended range and maxed the O2. I'm keeping all those successfully now but couldn't tell you if it's the range, the O2, or both.

29g high tech, 10g low tech halfmoon, and please see my 5g crescent journal.

My nitrates have only just began to fall due to plants coming back after a trim but mainly, I had very bad flow. I have noticed with the increased flow, i get way more growth, pearling, and nitrogen uptake.

the o2
my shrimp, both amano, and RCS survive 40-60 ppm nitrates regularly as well as very high co2, well over the 30 ppm range

Changed up the rams diet and her color changed. I'll look for some live food this weekend. They all like the black works so I'll pick up some.

I don't know where I'm going but I'm on my way.

keep in mind. varied is a big key factor for rams. IMO. bloodworms, mysis shrimp, and a good veggie diet with the blackworms should do wonders
