I have a catastrophe, need to lower pH immediately, should I get peat?
I have been having quite a catastrophe lately with my 40 gallon breeder tank. Pretty much every day for over a week now I have been losing fish. So far I have lost both my angels which I had for over a year, 6 rummy nose, 6 cardinals, and 2 otos. I had no idea why this was happening. I kept testing my water for ammonia, nitrite, kh, and chlorine but they all were reading fine. Then today it hit me, pH. I have no idea why I hadn't thought of that before, but I tested it and sure enough its reading the max on my test of 8.6. Usually the ph is 7.5.
Now I have to figure out what to do. First of all, I have an idea of why the ph is so high. I use purigen in my filter and a couple of weeks ago I bleached it to rejuvenate it. I have done this several times in the past with no ill affects. After I bleach the purigen I always rinse it real well and let it soak in water with seachem natural regulator. So, I immediately removed the purigen pouch and turned the filter off for now (another filter is running). The only other thing that changed in the tank recently is I added some bolbitis plants.
I guess my options are to add peat or more drastically get pressurized co2 or a RO unit. I have heard good and bad things about peat. But I am willing to give it a shot just to get the ph at an acceptable level and then take it out and see if it goes back to ~7.5.
Anybody have any other suggestions. Pleassseeee. It's depressing pulling out 2 or 3 dead fish everyday.
