My tank is almost 6 weeks old and I've had diatoms for just over 4 weeks and I'm wondering how long they'll last for as they're pretty ugly to look at. I used live rock from another tank of mine so it cycled pretty much straight away and my ammonia and nitrite are at 0 and my nitrate is around 5ppm (maybe lower). Could it be down to flow as I don't have a crazy amount of flow close to the sand bed? Any input would be great! Hahah
I clean the glass regularly so there's not a lot on the glass at all but my sand has a fair amount of diatoms.
