Default Re: what to watch out for

You don't have to get fancy, pool filter sand will work and you can pick it up locally at any pool/spa store for around $10 for a 50lb bag. While it's an inert substrate like Fluorite/Eco/SMS/SAS it's the cheapest and easiest to clean and it comes in a few different colors depending on your local stores.

You will need to add fert tabs and/or dose fertz in your water column but depending on what your trying to grow you'll need to do that with anything.
