    Can corydoras die from gravel?

    I have aquarium gravel, which I know isn't ideal, but I didn't think it could be problematic. Could it be the reason my cories are dying off? My water parameters check out fine, but I only have test strips. I'm getting a test kit later on today so then I'll know for sure if water quality is an...

    Easy way to change gravel to sand?

    Currently I have a blue coloured gravel in my African cichlid tank. I’m looking to change it to sand. What’s the easiest way to change this to sand? And am I right in saying it’s just play sand? Thanks

    Converting a Biorb Tank to a Different Filter/Substrate

    Hi, I have an 8 gallon Biorb Flow tank. I've had it for about a year and a half. I love the tank but I hate the filtration system, and the biorb ceramic substrate is tearing up my current Betta's fins (he likes to sleep on the bottom). So I'm wanting to change up the filtration system and...

    Help! I Can't Get Anything to Grow

    I have tried using root tabs (one per plant, at base of plant, replace every 4 months as per instructions) on my rooted plants and seachem flourish for my floaters and nothing seems to be working.

    Sand vs Gravel

    Hello guys, I'm getting a new tank(45 gallon) and I just had quick questions. I planned on doing sand because I read that it is better for angelfish and cories. Is that true? Is sand harder to take care of than gravel? Would a mix be good(like half sand half gravel)? Any other advice that I did...

    Adding substrate?

    Hi, I hope everyone is having a great day! I would like to know if it's safe to add more gravel on the gravel that is already in my tank or will this disturb the bacteria or something?

    Thinking of going from artificial decorations to live plants. How can I make this less stressful for fish?

    Hi again. I've had a 10 gallon tank for over a year but I'm starting to think of switching from artificial to live plants. How can I make it less stressful, since it could be a drastic change in aquarium? I can also provide tank parameters if needed, and any advice is appreciated. :) EDIT...

    Can I just plop live plants into my gravel aquarium?

    Hi, I am re-doing my 55 gallon freshwater tank. I want to make it more "river looking" and more realistic this time. I have a gravel substrate and was thinking about adding some live plants. Can I just add them in? Are there only specific types I can add? Or do I need a different...

    Planted Tank Advice?

    So as we're dealing with our 38gal, we're looking to get a second tank, possibly 65gal. We're kind of tired of gravel and want to switch to a planted tank with a sandy bottom. Right now the only plants we have in the 38gal gravel tank is two anubias plants and some moss balls. Other than that we...
