How To Ensure There Is Enough Oxygen In The Water

The marine aquarist does all sorts of water parameter checks to ensure the quality is high. A lot of money is spent on equipment and livestock. Once the livestock point is reached, occasionally problems will arise, particularly with fish in a fish only system. Though the aquarist may well be

Reverse Osmosis

The reef aquarist in particular is always trying to maintain high quality seawater. So is the fish only aquarist, though the quality demand is not quite so vital.

The aquarist test the seawater parameters as a matter of course. Most aquarists find that all is well, or can adjust to remedy an incorrect reading. There are aquarists though who use high quality salt and are particular about the maintenance. Despite this, they find that problems arise, often in the from of phosphate or nitrate. They then obtain filters to deal with these, creating more expense and more maintenance. There is nothing wrong with getting rid of undesired substances with specific filtration methods.

The question is, where are those undesired substances coming from. As said, if the aquarist is doing everything correctly, including feeding, it is unlikely that it is being generated within the aquarium. So where does it come from.

Should You Use Natural Seawater In Your Aquarium

It seems very reasonable doesn’t it. We keep seawater aquariums and so why not put natural seawater in them. It saves money too, no more buying those expensive buckets of dry salt mix.

The first consideration is availability. Seawater is heavy, around 10lbs per gallon. If the aquarium is fairly large the amount required will be many gallons, much more if it is an initial fill. Lots of large containers, all suitably safe for seawater, plus a vehicle that can safely transport the bulk and weight. Most aquarists live away from the sea, and the dry salt mix is the obvious way to go.

Salinity In The Marine Aquarium

We all know that the fish and corals we keep are salt water creatures. That’s why we buy those expensive packets or buckets of dry salt mix.

Fish only or reef aquaria are normally kept at a specific gravity (SG) of 1022 to 1026. It has been said that it is advantageous to keep a fish only system at 1022, as it is claimed that certain pathogens do not do well at a lower SG. Fish can be treated for some infections by lowering the SG even more. Reef aquaria are normally kept at 1024 to 1026, this seems to be the usual.

Water, water everywhere – not a drop to drink!

When it comes to keeping a salt water aquarium there is one thing that we are going to need and the clue is in the name – that’s right water!

But is water just water – can you just use water straight from the tap or perhaps from the ocean itself.

Well yes water is water but when we keep a salt water aquarium we are interested in any additional substances which are present.

Leaving natural sea water out of the topic for the time being as I think I will cover that in a future post let’s have a look at tap water.
