1.020 is way low for an anemone and corals. Ocean water is at an average of 1.026 and you should keep it over 1.023

Well 1.020 is too low. Ocean water is average 1.026. Inverts need 1.023-1.026. Also, hydrometers are very inaccurate. 80 nitrates is also very high especially for an anemone. They need pristine water, especially ritteri anemones.

Yes I understand that that's why I am doing daily water changes to get it down my tank has been perfect for 8 months and this is the first nitrate spike I've had. The water changes arnt doing anything that's why I asked if there is another way!

Why is your salt so low ? What brand of salt do you use? Also get a refractometer eBay has them for 30 bucks or you could get a digital meter which works great. You need better lights. Moon lights are only for show they have no benefits. And yes there are ph swings when your lights go off

I'm running two pl-18w sunlight bulbs on a 15" or 40cm tank. And led moonlight at night. I have 3 hydrometers and they all say the same thing that everything is ok

The sea is considered to be stable which for the volume taken up is not really surprising. The SG on the reefs though is perhaps surprising, as it can range from 1.017 to 1.031*. Specific gravity is affected by temperature and some variance in temperature is understandable. In addition, some seas are more ‘land-locked’ than others such as the Red Sea. So there is going to be variance.

I know there is variance but that does not make it untrue that 1.020 is too low for an anemone. You need atleast 1.023. I'm just trying to help just raise the salinity.

I thought that was it. Honestly, I've been at this for a long time. Trust me, you should consider slowly bringing up your salinity to 1.024. You'll have much less trouble keeping sensitive invertebrates healthy at that level. It's a very easy thing to do and it'll give your next anemone a much better chance of making it. Even with 0 nitrates and MH lighting it would have little chance of thriving at a salinity of 1.020. There's a lot of agreement in this thread about this.
