I've recently had an issue with ammonia spikes and it seems to have settled down with 50 water changes, but now my PH has crashed to 4. My tap water tests at 7 and the nitrate and nitrite in my tank are at zero. Anyone have any thoughts?
Tank is over 4 years running. Substrate is a very light sand. Decor is heavy on the driftwood which has been in there for years. Lightly planted. KH is reading at about 100 ppm. Tank has been cycled for a long time. Changed the filter about 8 weeks ago but seeded it with all the media from the old one and added more as the new one had more basket capacity. I'm baffledSalem said:What all is in the tank in terms of substrate, decor, plants, etc? Is the tank in the process of cycling?
If you have a kh/gh test you may want to use it to figure out those levels. KH is basically what keeps the ph stable and when its under 4 it can allow things to swing pretty drastically.
Not sure, I've lost three fish to this (all the Same species) and I can't work out what the problem is. I used carbon for the first time as it came with the new filter. I doubt that it's where the problems lies but I'm going to bin it tonight and replace it with other mediaH Farnsworth said:Could a massive bacterial die off produce enough co2 to lower the pH? Ammonia is a base so that’s not it
