You may test your water when you set up your tank and find it perfect, but slowly pH starts to creep up or down. pH is a measure of whether water is acid, neutral or alkaline and is measured on a scale of 1 -7=acid 7=Neutral and 7- 14 =alkaline. #3 – Bacterial Bloom When these plants absorb carbon dioxide, the pH rises. If your aquarium has experienced a pH crash, your fish may show signs of stress, such as frantic swimming, lethargy, rapid breathing, or other erratic behavior. One of the most important ways to do this is to constantly monitor the aquarium pH and increase it if need be because most saltwater creatures thrive in a high-pH environment. pH is a measure of whether water is acid, neutral or alkaline and is measured on a scale of 1 -7=acid 7=Neutral and 7- 14 =alkaline.

So what may seem like a small difference in the readings can actually be a major difference in the long run. Different fish thrive in different environments, and there is no one pH level that will work for all types of fish. pH goes down over the week due to the high fishload and heavy feeding.

While it is easy to increase the KH, lowering it is a bit complex. The key is to maintain a relatively stable pH with no sudden spikes, and most fish will adapt. Test the tank water using a simple aquarium water testing kit, and you’ll probably discover that the water is very alkaline with a correspondingly high pH level. The pH up and down stuff has only a temporary effect, so the net result is pH fluctuations. Monitor the pH of aquarium water with a pH test kit. Changes in pH are invisible so without regular testing changes can have an effect before you even notice something is wrong. 5 days ago I did a 50% water change, which brought both the kH and the pH back to normal.

Some aquarium substrates, like crushed coral, are intended only for use in marine aquarium or tanks where a high pH is desired, and can have adverse effects on aquariums where a high pH is not desirable.
