Kirsten Posted February 9, 2021 Share Posted February 9, 2021 (edited) So, I totally love my endlers and platies, but I think I'd like to get a separate guppy & possibly swordtail tank next. I have naturally soft, neutral water, about 50ppm GH and 20ppm KH out of the tap, which the plants make even softer. My platies and endlers are happy with the wondershell and handfuls of crushed coral I scatter over the regular gravel substrate, and they do raise the GH quite a bit, but the KH is almost always close to 0. Luckily the plants also seem to help the pH stay relatively stable. So for the guppy tank, I want to be set up for success with the best substrate for a steady supply of KH buffering, while also making my plants happy and hopefully looking good, too. Since I don't need a super high pH, I was thinking of going with old fashion crushed coral, but I love the fine and soft sandy texture of aragonite. I also love the look of black diamond, which I think would set off a guppy's colors really well, but realize I'd have to just supplement with crushed coral in a filter bag to keep that color consistent (and might put some brown vermiculite underneath to help support the plants). What would you recommend? Are the benefits of aragonite worth the extra cost? Are the benefits of a coral substrate negligible enough that I should just go for black diamond and supplement? Is there another substrate I'm overlooking that you'd recommend over all of these? Edited February 10, 2021 by Kirsten Link to comment Share on other sites More sharing options...
