    Greetings. I am planning to construct a very large tank. I’ve thought about using “safe cement” to construct some of the structures (the back wall to look like the side of a stream) etc. I’m planning, after construction, to paint the concrete to further add to the naturalness. It could also include drift wood, actual rock etc.
    What types of cement and paints are aquarium safe?
    Thanks very much.

    I don’t think cement is in itself bad for fish, but it can leach hardness into the water.

    If you want to be absolutely sure the paint is safe, get some “Potable Water Epoxy Paint”. It’s quite expensive, but it is meant for water tanks with drinking water, so should be OK for fish too.

    not 100% sure but i know you can buy paint for ponds, think it is called G5 or something like that, comes in many colours.
    cement as far as i know leeches all sorts into the water so is quite toxic (from what i have read over the years)

    You get heavy metals bound in cement – not sure if they would leach out or not?

    sorry – no help what so ever am I!

    i know this is a bit late
    but you should maybe try fibreglass i seen a youtube clip where a guy made stuff for his tank
    using polystyrene then fibreglassed it then used a solvent to melt the polystyrene then painted it
    with a safe paint or you could use koi kote its 100% safe its a type of paintable resin

    am i correct in sayin that cement is full of lime or do they use a different ingredient for pond cement

    hope this helps

    Cement is fine to use but it’ll need to be sealed with something. There are various ‘pond paint’ sealants available in the UK and presumably in the USA too, and I think the most common ingredient is polyurethane. Not sure if there’s a specific pond-safe cement though – never seen one myself.
