• Welcome to ScapeCrunch!

    We are a friendly, online community of people interested in planted aquariums. We support and help each other learn and grow. It is our sincere hope that you will join us and find our tight-knit community valuable and fun!

    ScapeCrunch is different than Facebook Groups. Here's how:

    • It is a place where you can make long-term friends in the planted aquarium hobby and have long, multi-day talks on specific subjects.
    • Unlike social media, online communities like ScapeCrunch are much better at curating collective knowledge and in fostering deeper relationships.
    • They lend themselves better at long-form discussions.
    • You can maintain a thread on your personal aquarium with pictures and details. Other members can comment, help and ask questions. You can do the same with their Member Tank threads.

    Where Facebook is more like a large city-wide party, ScapeCrunch is more like your neighborhood bar "where everybody knows your name. And they're always glad you came." It's always fun to go to large parties but it's at the local bar that you feel people really know you. The great part is that you can and should go to both!

    Please consider joining to become a full fledged member of our growing community of planted aquarium obsessed enthusiasts. Let's grow together!

    Hello Everyone,

    As title states, where does everyone buy their macro powders from? How many people use a DIY approach and what powder are you using?

    I've know there are likely common "non fish tank" dry powders people have been using for the big 3: macros, no3, k, and po4.

    Example from reef keeping, mrs wages pickling lime and leslies pool supplies calcium hardness for raising calcium.

    MBFerts.com, esp good deals for 5 llbs or more. Not sure if 1 lb is cheaper than places like gla or nilocg, havent looked

    It probably is because they dont use fancy packaging. It'll come in a zip loc with what it is written on it with a sharpie

    They do show you the source on the product page though. All this they make clear and state that plain packaging isa main reason they can sell so cheap

    For our needs buying ferts is all about price, esp macros and secondary macs. KNO3 is KNO3, very little difference in the lower grades we use
