    Is black water necessary for a planted tank ? Understands that it helps to reduce algae growth. Will the black water makes the water brownish ? Can't decide whether to get it.

    I use Mr Gan's (supposedly) South American blackwater extract, the staining is not apparent after a few hours.
    why I don't do garden hybrids and aquarium strains: natural species is a history of Nature, while hybrids are just the whims of Man.

    with or without, there's no observable difference

    If you would want to reduce the ph, can be done using CO2. Yes it does reduce algae at lower ph. Have loaded SERA peats, difference is KH down from 7 to 4. PH from 6.8 to 6.6..be careful your ph may drop lower than that if you have CO2 on the whole day; do monitor your ph.
    Everything that lives and moves will be food for you.
    Just as I gave you the green plants, I now give you everything.

    yah, colourless blackwater extract, damn chim [:]

    anyway Mr Gan's blackwater seem to make my cardinal much more healthy when they were in a bad patch. Anyway one bottle last so long there's no harm putting lor.

    i think the black water or peat extracts are meant for those keeping and breeding soft water fishes like discus, angels, tetras, gouramis, barbs etc.... to reduce the pH and simulate their natural blackwater habitat. With planted tanks, some use it to lower pH (and partly to fight algae, which are said to dislike low pH). But most plants (except crypts) don't thrive in pH below 6 as well, so it's your choice. Also it screws up the KH/pH table used for determining CO2.

    black water extract and peat

    would i be able to use black water extracts and peat in an aquarium with Co2 injection? will it alter my pH too much?

    Usually back water extract and peat lowers the pH of the water column. Some hobbyist used it together with CO2 injection, but usually, most would prefer not to use it as it tints the water to a brownish shade.

    Cheers,
    I have dwarf cichlids in my tanks! Do you?
