    Hey all.

    I started a little fresh water tank for the kids about 2 weeks ago. Added some water from neighbour for bacteria, filled it up with ro water, added a filter and a power head, and voila, 2 weeks later all fish are dead... even the pleco.

    So how the hell can I keep marines alive easily, but manage to kill freshies? So I want to do a planted fresh water tank for them, but don't want to kill the fish again. What am I doing wrong?

    Yeah @dallasg that's what I thought also. Will have to rather just get more water out of my bud's tank...

    What kind of substrate do they use for a planted tank?

    Don't use RO water rather tap water and no need for water from other tank add a little bit of prime and you're good to go. Depending on what you wanna keep will determine what substrate you need

    Thanx bud, will do.

    Yeah that's what I'll do next time round. Have some prime left from my marine startup. Planning on keeping plants and just a few nicely coloured fishies, no predators (my girl wants an angel and my boy wants a Siamese fighter...)

    It's only a little standard 600mm tank with plastic hood I got from a neighbour. Don't want to go all pro, it's mostly for the kids. But want to do a planted tank.

    I used pool filter sand for substrate on my planted tank. It just needs to be rinsed well.

    Another thing that i found very helpful was osmocote pellets for nutrients

    I use ro water on my freshwater tanks without problems. I use to use tapwater but thats the same as using tap water in your marine tank. Dont do it. What i did find usefull is using tap water from geyser and then let it stand for day or two. Worked better than straight from the tap.

    Planted tanks need all sort of gadgets. Need special soil, need co2, need lights, so ja...can also become costly but also very rewarding if done right.

    You missed a basic step when setting up any tank.... You didn't cycle the tank. Unless you using probiotics a fresh water tank should take around 4 weeks to finish its cycle.

    Mistake number 2 was using pure RO water. RO water has no buffering capacity which causes the ph to swing up and down rapidly sending your fish into osmotic shock and eventually death.

    Water does not harbor bacteria, or very very little in any case. Bacteria colonizes on gravel, rocks, filter material and even aquarium glass. To speed up the cycle you could use some of those.
