How many pounds do i need for a 55gal

Determining how much substrate to buy for your new aquarium depends on the size and shape of your tank, as well as the depth of the substrate bed you wish to achieve. We suggest 1 pound of substrate per gallon, to achieve a 1 inch bed or 2 pounds per gallon, for a 2 inch deep bed.

I bought 4 bags of this 6++ months ago. Is it still safe to use I don’t see an expiration date on it

There will be no expiration on this freshwater substrate. It may be used for an extended period of time if stored properly, in room temperature (below 150 degrees), out of direct sunlight.

I’m trying to keep my PH low (5-6), but consistent. The description states that it helps maintain PH. Does that mean it increases PH to basic or just keeps it consistent?

This substrate maintains proper pH at a healthy level and enhance buffering capacity, along with providing essential inorganic elements.

does it raise the hardness of water like other cichlids substrates

The substrate will not harden the water, it immediately removes nitrogenous waste (Ammonia, Nitrite and helps remove Nitrate).

How would other cichlids such as an Oscar or Jack Dempsey work out with this substrate?

Oscars and Jack Dempseys prefer softer water environments. This Cichlid substrate contains Aragonite, it will create a hard water environment and act as a pH buffer. This wouldn't be recommended for those species.

is it safe for invertebrates? Does it have copper?

This will depend on the type of invertebrate. Because this substrate contains aragonite in freshwater aquariums this will make the water hard. If they are able to withstand hard water this would be suitable. Essential trace elements provided by Bio-Activ Live are: zinc sulphate, calcium chloride, m...more anganese chloride, cobalt chloride, copper sulphate, sodium molybdate, strontium chloride, nickel chloride, potassium bromide, sodium silicate.
