    I'm setting up my tank and I have been going back and forth on different substrates..

    First I bought a very fine cheap quality sand but read the reviews and people said it was too fine and kicked up causing the water to appear cloudy.

    Therefore I went with a more course sand Gotham Aquatics | ESV Ultra White Calcium Carbonate Reef Substrate (Fine Grade) 50 lbs | isgon26 ipower and people say it still may cause cloudy water..

    I hear crushed coral wont kick up but then I hear it will spike nitrates.

    So if I want crystal clear wter which substrate should I choose?? ​

    What types of fish do you plan to keep? That will determine your options. I.E.- if you wish to keep gobies or other burrowing/sifting fish, then it will need to be relatively fine; if you're planning to house larger free-swimming angels, triggers, etc, then you can use most anything.

    BTW- crushed coral can be vacuumed periodically with an aquarium gravel-vac to keep it clean...

    Thanks for the replies..

    I was mostly thinking about housing Triggers, Angels, Tangs, etc.. But I heard it is good to get some bottom dwellers for Algae control, so I dont know...

    Anyone else have any suggestiongs? All input is welcomed..

    I like Carribsea Fiji Pink. It's fine enough for jawfish, gobies, pistols but large enough to not blow around (once the bacterial biofilm grows on it).
