Hi friends,
I need your help with my tank. I have been almost a week now that my setosa has begun to stain with white, is dying. And already about 20 days ago some of my zoas were closed and each time they look thinner as if they were also dying.
I have some suspicions that it may be, but I have no idea how to fix the situation and I will explain the whole context so that they can guide me in how to act and solve the situation.
Approximately 2 months ago I used dosing machine to add Ca and Kh these parameters were maintained as follows: kh 9 - 10 Ca 470 both according to Red Sea, the Ph during the day was around 8.10 and 8.25 according to Apex. In this time of 2 months I changed from using metered to using Calcium Reactor, as I had never had a reactor and everything I read gave me the impression that it was easy to adjust, what I did was: I started with 1 drop every 10 Seconds, but the Ca rose to more than 500 and the kh was decreasing and had already reached 8. Then increased to 1 drop every 5 seconds and the Ca was kept at 500 and the kh had already gone down to 7.6, I kept increasing the drip And it was one drop per second, the Ca under 480 and the kh to 7.2. Among all this the pH was varying downwards according to Apex. Seeing that the kh almost at the lower limit, increased dripping even more, and stopped being dripping and became a small continuous stream of water from the Calcium Reactor, with each increase in the dripping from the reactor, increased The flow of Co2 to the reactor to maintain the reactor with a pH of 6.50. At this point already the pH of the tank in the day reached 8.05 and in the early hours when all the lights are off went down to 7.80, almost simultaneously I had a problem with the pH probe of the tank as it was out of the water and decalibrated, I could not calibrate it at that moment. All this in time took almost 15 days to happen.
Prior to this I had made the decision to eliminate the macroalgae of the refuio since they were dying for lack of nutrients, then already at night the problem of the balance of the pH of the tank increased because there was no consumption of Co2 present in the tank by The nights as is normal for the production of Co2 tank.
However while maintaining the water jet reactor and the Kh reached the level of 7.8 and 8.0 and the Ca 450 and 440., I do not see it badly as it is within normal and the corals looked good and growing and thus lasted Almost 1 month after balancing kh and Ca.
Now after this, I have almost 15 or 22 days that the zoas have resented, the setoses are on the verge of dying completely, so I feel the problem is, that such a large flow of water from the reactor for my fish tank is not Because the reactor is for tanks of up to 400 gallons, my tank has a total volume of 150 gallons and I do not have so many corals consuming that level of reactor addition. So I think by adding so much water from the reactor that comes with a very low pH, it does not let the pH of the tank remain above 8 for 24 hours.
I already started to use macro algae again (but they are very few) and I am using lighting in the shelter of 8 hours to the inversion of the display. However this I have it 2 days ago, the change in pH at night is noted, was down 7.8 and now with algae down to 7.9, however I still think it is very low.
I intend to lower the flow of the reactor to be drops again, so do not add water to the tank with such a low pH, then I think that if under the level of the reactor flow I will contribute in that the pH of the tank does not go down so much. But the problem that I have and doubt that arises is that if the reactor adds drops again, the kH will go down as it did the moment I installed the reactor almost 2 months ago. So how do I make this not happen? Was it due to an imbalance of having the Ca in 470? If now the Ca is in 440 can the same thing happen that the kh is lowered?
What would be the ideal way to run the reactor and level the Ca and kh, without affecting the pH of the display?
As additional data to have it more summarized is:
150 gls system
Ca 440 ppm
Kh 7.8 - 8.0
Mg 1280 ppm
Po4 0.03 ppm
No3 4 ppm
Sality 1.025
The movement of the wavemaker, the lighting, position of the corals in the tank, have not changed at all for a long time.
Tks a lot for help me.
Regards.
