Crushed coral
The thickness of this sediment can vary, depending on the extent of the crushing. It consists entirely of pieces of the skeletons of corals and other similar animals.
Crushed Coral
As discussed above, crushed coral raises the pH in the aquarium. Therefore, it is not a good choice for fish that prefer water with a low to neutral pH. It is perfect, however, for fish such as African cichlids.
Crushed coral A Calcareous substrate material with pH buffering abilities, for marine aquaria.
Cuttings Detached parts of stem plants: they take root after planting and become new plants.

Crushed coral is used as substrate in most saltwater aquariums. It helps to maintain the high pH that is enjoyed by marine fish.
Substrate is crushed coral, natural color.
Rocks I used are from a local landscaper. They mainly consist of non-reactive sandstone and slate. Also, some of the larger nicer rocks I collected myself from the Dead Sea in Israel.
5 gal bucket for crushed coral ($3 Home Depot) 3.5 gal bucket for drip tray ($3 Home Depot) 3.5 gal bucket for trickle filter stand ($3 Home Depot) 3.5 gal bucket for trickle filter ($3 Home Depot) cover for 3.5 gal bucket ($2 Home Depot) 7.
Before that time the bottom of the tank was covered with a mixture of crushed shells and crushed coral making a layer about one inch thick in most areas. The rock was placed on top of this layer ...
To maintain a stable pH in the upper levels of the pH scale for fishkeeping, I would recommend using a buffering substrate such as crushed coral. You can add crushed coral to your existing aquarium.
Aquarium substrate such as live sand or crushed coral
Live Rock
Saltwater Mix
Saltwater Hydrometer or even better a refractometer ...
Crushed coral and crushed limestone will dissolve, raising the hardness and pH, as well as increasing the buffering capacity of the water. These are used in marine setups and with fishes like African Rift Lake cichlids.
Sand is the preferred substrate and will help keep the pH up, but some have used crushed coral or a mix of gravel and crushed coral. Provide lots of passageways and caves formed with piles of rocks.
Starting with a substrate of play sand, pool filter sand, and crushed coral (to keep the water buffered up naturally) the tank was off to a good start.
If your tank KH is not high enough, you can easily increase the buffering by adding some crushed coral (from the saltwater tank supplies at the lfs) in a filter bag in your filter.
crushed coral or sea shells), etc.
How frequently should partial water changes be made?
The more frequent the changes, the less water that needs to be replaced.
If you plan to use a substrate, it should be fine calcareous sand, since the eel often travels along the bottom and may injure itself on the typical crushed coral substrate.
Description: A member of the Mbuna (or "Rock Dwelling" cichlid) family, their environment should be densely decorated with rocks and rock caves, fine gravel, fine gravel with crushed coral, or even sand for substrate, driftwood, Java Ferns, ...
Got rid of the crushed coral substrate (Sytsems will work with it, but can cause nitrate problems down the road) 2. Got rid of the Bio-Wheels in our Bio-Wheel 330 (also poses nitrate problems) We just use ours now to run carbon every so often. 3.
Aquarist believed that they had an easier, quicker solution in under gravel filters and crushed coral. Along with the water, detritus and junk was pulled through the crushed coral, which clogged the filter bed.
gravel, crushed coral, sand, shells, rock) out and clean it in chlorinated water, or a medium that would kill the necessary "nitrifying bacteria" that breaks down toxic wastes (ammonia.) If this filter is so much as partially killed, ...
It is best to use a calcareous substrate such as crushed coral or dolomite. These substrates will, at least initially, help buffer the water by adding ions to the buffering system.
Hardening materials such as crushed coral shell in the filter will gradually and nauturally raise KH and in turn pH.
Filtering the water over crushed coral is the method of choice for raising the pH. The use of limestone rocks in decorating the tank will also raise the pH, but keep in mind that you will not be able to adjust it readily.
from crushed corals, bio-rings, etc. The inner portion of sintered glass has a lot of very fine micro-pores,
which do not let much, if any water pass thru'. As a result, the denitrifying bacteria can live in here.
Coral sand is a mostly white medium fine crushed coral and shells (though sometimes Aragonite is added). The shells of freshwater or marine invertebrates is made of [Limestone], the mineral calcite (calcium carbonate CaCO3).
To help keep the pH at the required level sand or crushed coral intended for salt water tanks can be used. But, gravel is also an acceptable substrate.
The aquarist must provide an abundance of rocks for mbuna to feel at home.
Use crushed coral instead of gravel for these fish.
Perform frequent partial water changes.
Substrate: Material used on the aquarium bottom. Examples include gravel, crushed coral, crushed seashells, et cetra.
Substratum: The many different layers of substrates found in nature or in the aquarium.
Marine grade substrate is also effective at buffering pH levels (helping to keep them within normal limits.) Good substrates for the marine aquarium include crushed coral, dolomite, and aragonite gravel.
For example, crushed coral leeches calcium into the water of an aquarium. This can raise the pH and KH (carbonate hardness) in a freshwater planted aquarium to damaging levels.
Substrate: The material making up the base on which an organism lives or to which it is attached. Also, the material used to cover the bottom of the fish tank. Examples include gravel, crushed coral, crushed seashells, and sand.
what's up everyone just thought I would throw in an update on my 75gal african cichlid tank. we bought the tank originally with blue gravel in it and ever since i've hated it, thinking it was meant for a toddler so after taking out the crushed coral ...
To harden the water, filter the water through dolomite or crushed coral until the desired hardness is reached.
Electrical Conductivity: By running an electrical current through the water, the level of conductivity can be found.
Crushed coral is available too, but realize this is not coated with epoxy and will alter the chemistry of your water (raises the hardness). You can also use just about anything found in nature, although I wouldn't suggest it.
Do not attempt to keep the Red Coris Wrasse on crushed coral or similar substrate as they have a poor survival rate on such substrates.
