Hi
Just tested water, I know the kits are supposed to be rubbish but you have to have some sort of guideline, anyway, my tank comes up at around 80 ppm maybe higher, hard to tell with API test kit, that’s in a tank that has only shrimp in, i ei dose so I guess I can leave out a lot of the nitrate added to the macro mix, am I right about that?

Are you doing 50% water changes alongside the EI dosing? The idea is it resets each week. That seems quite high so I wonder if something other than ferts is causing it.

The API Test Kit is not very useful for nitrate (NO3) testing As you can see in the post the level could be anything.

I wouldn't. The nitrate you dose is not the problem - If you know how much you dose and whatever your tap water provides that should be the approx level in the tank - give or take. The nitrate that is buildup due to waste, that is usually the problem.

Cheers,
Michael

Ok, that is of course a different matter. Well, if that is the case you wont have to add any really. Just make sure it stays at a certain level - the best is to check with the water dept. of your city.

Yeah about 3 weeks now
That would be my guess for the source then. I would continue as normal, and monitor it. Hopefully it will drop down again. Would be worth keeping an eye on the occupants/ammonia level, I'm guessing though it's already on the way to stabilising.

Hi
Yeah it’s stable, I’m not going to worry the shrimps are breeding so all’s well
