Hello all! I definitely need some advice on how better to manage my nitrates in my tank as a recent Spike and been killing off my invertebrates. **All fish are completely fine and healthy** *Pic of tank attached 35g Planted tank for small tropical fish 0 amn 0 nitrite 40+ ppm nitrate! *Tap registers about 10ppm PH varies between 7.8-8. Usual water changes 30% a week, but increased as soon as I detected the Nitrates. I bought two freshwater Pom Pom crabs and about 10 RCS about 2ish months ago and they were thriving. Just within the last couple of weeks the RCS started to slowly get sluggish and die off, and just within the last couple of days the crabs did as well. Nothing changed since introducing them to the tank. I do have a lot plants however not much ground cover, so my normal water changes I can usually get most detritus out. Even after doing more frqfrequ water changes to keep the nitrate level diwn they still weren't able to make it. Any better advice other then more water changes and keeping tank clean? They keep rising and I'm not sure if other factors might be effecting it.
