Hello team, I need some help.
I previously had a healthy aquarium with fat and happy fish and a handful of corals and inverts. I now have 1 coral left, no inverts, and still fat and happy fish.
My problems started about a month ago, I noticed that my overall pH levels were declining. Around 1 month ago, the levels were generally 8.2-8 (swinging day and night). Then my average pH slowly started to drop to where the maximum was 8.1 then 8. THEN, about 2 weeks ago, I had a massive drop overnight to 7.7 and I could not recover it fast enough. I lost all my corals and inverts (except the 1). .
I cannot figure out what caused the sudden drop and even now it's still not recovered. The average these days is 7.8 and it's honestly slowly dropping every day.
To test, I have a Neptune system that has been calibrated and i double check with strips which are consistent with my readings.
My other parameters are fine. I did have a moderate increase in ammonia/nitrates after the die off, but some water changes and medication did correct that and we are at normal levels.
However, pH is still a problem. I have not changed the water source or the salt I use to mix. I did not change the fish diet or anything. I am at a loss. Tank is 6 months old and was really doing well until the 2 weeks ago.
Alkalinity seems fine. I have tried just using pH increase which only temporarily raises it, but seems to tank even faster after I use it. I have tried removing the lid to improve aeration, but it doesn't help and I really doubt that would cause that big of a swing. Any advice/insight would be helpful.
55 gal
3 bagnnai cardicals
1 blue chromis
1 purple dottyback
1 fairy wrase
1 neon green starburst coral left
1 naked clown in QT due to parasite, but doing well currently after some prazipro treatments.
