All test good BUT..

[Babygecko1233]

Tested my tank today, before adding a slab of GSP. Every thing tested right on. Except for Nitrates! They are high. Well I found out that gps thrives on it. Which is nice (my fav). So that will bring some nitrates down right? I also just added cheato and a red kind of macro algae ( not sure what kind). To bring down nitrates..My question is...Will this drastically bring down my nitrates!? Just don't want everything to die. I have a Condy nem and a carpet nem and an arrow crab and clown fish and Sargent major and goby

Our nitrates are the highest level on my chart

Is that why my shrimp died?

Possibly. For nitrates water changes are your very best friend.
