Something I don’t like to see however is when my fish are floating dead instead of swimming, which can happen if the pH level is off.

“How To Lower Ph In Fish Tank? ” is a question that lots of people have. With regards to the type of fish you have, the pH levels in the aquarium need to be quite specific, if not you risk killing the indigent fish. Generally, the pH levels have to be a little on the low side. So, you might be wondering, how exactly do you lower pH in your aquarium.

What causes high ph in aquarium

High Alkaline

pH changes in the aquarium, even if small, can have serious health effects on your fish. High alkaline, aka basic water, make a difference your fishes’ gills. If your fish dart backward and forwards, check your pH, as this is a common symptom of high alkaline and could result in fish death.

High Acid

An acidic aquarium can result in the production of excess mucous by your fish. That is due to a rise of toxic elements promoted by acidic aquarium water.

Catappa (Almond Leaves)

Catappa is a kind of Indian Almond leaf that acts whilst the “poor man’s water conditioner, ” softening and lowering the pH. Almond leaves can also release a number of tannins in the water, so you might want to soak them to get the color leakage out ahead of adding them to your tank. But the color huge difference can often be fairly subtle, especially compared to other techniques that release colored tannins into the water.

Also, Catappa will, without fail, help naturally lower the pH balance of your tank by filtering the water just because they filter contaminants out of the air. There is also some speculation that almond leaves work as an all-natural health assist in aquarium fish, and some say that it could prevent or cure disease, working as an antioxidant and anti-inflammatory, but the clinical research to aid such claims is still happening and not yet fully confirmed.


Adding a piece of natural driftwood to a tank community can gently help lower pH levels. It really is, however, a terrific way to color your tank’s water, so in order to avoid that, it is strongly recommended that you either soak your driftwood in a different container (completely submerged, not floating) for 1-2 weeks prior to introducing it to your tank, or boil it to sterilize it.

Peat Moss

Peat may also be a great way to help naturally filter the pH levels of your tank, but, again, can discolor your water. Many aquarists recommend pre-treating your peat moss in a separate bucket for some days before putting it into your tank to be able to dissipate the yellowish tinge that natural peat can provide water.

RO water

RO water refers to Reverse Osmosis, an activity of water purification involving (according to Wikipedia. org) the use of a semipermeable membrane that removes many types of molecules and ions, resulting in fresher, softer water.

The filter allows water and smaller ions to undergo while keeping the heavier, larger ions like lead, chlorine, and other water pollutants filtered out generally. A good RO system can cost a couple of hundred dollars, nonetheless, it is a natural deionizing process that can be used in aquariums easily.

An RO unit can help provide a constant, stable pH level, and may filter up to 99% of water contaminants. An RO system will need occasional filter replacements, but is a superb long-term solution if you have hard tap water as well as your fish aren’t happy in it.

Proper ph for freshwater aquarium

There’s absolutely no “normal” pH that relates to all fish. Because fish originate in ponds, rivers, streams, lakes, and oceans that have different pH levels, their needs are different. Saltwater fish prefer an alkaline pH of 8. 0 or above. Freshwater fish thrive in a range below that, approximately 5. 5 and 7. 5, with respect to the specific species.

Keep in mind that pH is not static, it changes over time; actually it even changes throughout a single day. Typically it drops through the night and rises during the daytime. The pH will change as new fish are added or removed, as water is added or changed, and as the biological processes change in the tank.
