As the title states, I am trying to clear out a very significant amount of nitrates(>80ppm as of this morning) via a large scale water change and would like my fish and corals to remain alive throughout the procedure(needless to say I’ve never done a water change at this scale before). I’ve taken care to ensure the replacement water is as close to identical to the tank water in terms of pH as possible. In this situation, should I go through with the procedure and replace all the tank’s water, or will changing only 50% of the water be sufficient to remove most of the nitrates? I’m mainly just worried about my animals dying of shock and potential air exposure.
My stock:
1 Dascyllus melanurus(I actually have no clue how he’s survived all these years in here)
2 hermit crabs of some sort, one with blue legs and another with red. They have similar limb proportions and I was never able to get a good look at them(or cared enough) to get a positive ID. They’ve been around since the beginning and I suspect they’re immortal.
3 - 4 various Cladiella spp. leather corals.
1 head of a very sad, very unhealthy branching hammer coral that keeps getting covered in filamentous every few weeks.
1 red or orange - coloured mushroom coral lodged in a hole that I can’t get a good look at.
2 bubble anemones that split from a single one like one and a half years ago.
2 rock flower anemones.
