    Dear All,

    i am in the process of setting up a small indoor AP system inside my house and just got all the equipment set.

    For the media bed - i got some 20 mm blue metal gravel. As it is recommended to test for Lime, which i am going to test soon.

    I need to know in case i find traces of lime, what can i do to get rid of the lime and use the same gravel ?

    Kindly advice.

    Regards,

    Jomy

    Hi Jomy, Welcome to the forum.

    If it's a small volume of gravel, with only a small amount of lime inclusion, then you could put it into a plastic drum etc, and fill it up to the top of the gravel with vinegar, or Acetic acid, or Hydrochloric (Muriatic) acid. Then leave it until it stops bubbling.

    If it's a large volume of gravel, or there is a high level of lime inclusion in the gravel, then your best option IMO would be to replace it with a gravel that doesn't contain lime.

    Dear Yabbies,

    Thank you for your advice.

    I did the vinegar test and noticed the bubbling is very less and from few stone, then later i observed there were some white type of stone which get powdered easily.

    I decided to sort them out 1 by one as i just have only 1 media bed and yes the volume of gravel is very less. After a through wash of the sorted gravel i did random vinegar test and found no bubbling.

    Good now i am just running the complete system and setting the flow and air etc.

    will start to cycle without fish in a day or two.

    Once again thank you.
