Seachem Ammonia Alert

The sensor itself IS replaceable and sold separately......but only in the US. Check out e.g. www.marinedepot.com or thatfishplace.com and also petsolutions.com

Tank crashed could be due to high nitrate and in which case this ammonia alert can't alert you

Ammonia can be at zero or non detectable but the nitrate can be high and don't forget that one of the main causes of tank crash is due to high nitrate.

So is Nitrate the main culprit that will cause the tank to crash? When we say tank crash, do you mean that most corals cannot survive? Also can I say measuring Nitrate level is more important than the rest?

Thank you.

Nitrate and phosphate need to be kept low for fishes and corals. Corals cannot tolerate high phosphate. My corals tend to do better whenever I replace the phosphate removing media like PurePhos.
