5 Aquarium Tricks I Wish I Knew Sooner

5 tricks I wish I knew before I built my first aquarium. When I started in this hobby I thought I had everything figured out, but aquariums have a funny way of proving you wrong. Some of the things I've learned could have saved me months of frustration if I'd known them earlier, so in this video I want to share a few tricks that can help you avoid the same problems and keep your aquarium running smooth from the start. Always do a little research before choosing your hardscape, and I mean always. This applies to anything you put in your tank, rocks, wood, even the materials you use to glue or stack things together. Hardscape is what gives structure to an aquascape, but it can also be what ruins your water parameters if you pick the wrong thing. I learned that the hard way. A few years ago I bought these rocks, they looked great, perfect for what I wanted, but I didn't research them at all. They never stopped breaking down in the water, they constantly created this fine dirt that spread everywhere, and they were heavily affecting my water parameters. I used them in two aquariums, the first time I had no idea what was happening, and the second time I thought using less of them would fix the problem, it didn't. Even with a small amount, the same thing happened, my KH started rising, my water got cloudy, and the tank took months to stabilize. Both aquariums eventually found balance, but I'll never use those rocks again. The truth is, not all rocks are safe for aquariums, some dissolve slowly, adding minerals and changing water chemistry in ways that can stress your plants and fish. So before you spend money or build your layout, take 5 minutes to look up the rock type you're using, doing that little bit of research can save you months of frustration and keep your aquarium stable from day one. Never add a large amount of soil to an already cycled and established aquarium. I once made that mistake, thinking I was improving my setup, I'd heard about how beneficial active soil could be, and I felt like the amount I had wasn't enough. So I added a whole bunch all at once, and technically, I wasn't wrong, active soil is beneficial, it softens your water, gives nutrients to your plants, and provides great surface area for beneficial bacteria. But here's what most people don't realize, when you first add it, it releases ammonia into the water. In a new aquarium, that's completely fine, it actually helps kickstart the cycling process, but in an established aquarium that already has fish, that sudden release of ammonia can be devastating. You're basically forcing your tank to start cycling all over again, with your fish already in, ammonia spikes happen fast, and even a small amount can cause serious stress or even fish loss. I lost a few fish that way, simply because I didn't realize how strong that initial ammonia release could be. The tank eventually stabilized after a few weeks, but it's not something I want anyone else to experience, so if you ever plan on adding more soil to an existing setup, do it in small amounts, add a little bit at a time, test your water, and give your bacteria colony time to adjust, a small change done patiently is always safer than a big one done all at once.

Since we are already talking about soil, let's talk about reusing old soil, for a long time I was reluctant to do it, and the reason was base layer fertilizer, I used to use the kind that mixes in with the substrate, and once you do that, there's no way to fully separate the two, when you try to reuse it later, you end up with base fertilizer mixed all the way to the surface, supposedly, base layer fertilizers are too nutrient rich to be exposed directly to the water, people say that if they are exposed, they can cause algae blooms because of how much they release, and for a while, I believed that completely, I had algae issues in a new tank I set up a while back, and I always blamed that exposed fertilizer for it, I thought the nutrients were leaking out and feeding the algae, but over time, the tank stabilized, the algae disappeared, and the fertilizer was still there, exposed, what I learned from that experience is this, once your aquarium finds its balance, even a few bits of base layer fertilizer won't cause issues, the plants start absorbing excess nutrients, the bacteria kicks in, and everything will be just fine, so don't be afraid to reuse your soil, even if it's mixed with some fertilizer granules, it's not nearly as dangerous as it sounds, and if you do want to remove the base layer fertilizer pieces from the surface just for aesthetics purposes, you can use this little vacuum I made, it's perfect for that, it cleans the debris and fertilizer pieces right off the top layer without removing any water from the tank, you'll find a link for it in the description. People often think smaller tanks are easier, but in reality, bigger tanks are much more forgiving, I've kept several nano tanks, and they always find balance, but the same way they find balance, they can also lose it, when anything happens, it happens faster in a small tank, if you lose a fish, the ammonia spike hits harder, if the temperature in your room changes, your tank temperature shifts right along with it, even something simple like a little extra fertilizer or a delay in a water change can throw things off, everything happens faster in a small volume of water, because there's less to buffer those changes, a bigger tank on the other hand has stability, it takes much more to knock it out of balance, because larger tanks give you time to catch problems before they become disastrous. Now that doesn't mean small tanks can't thrive, I've had plenty of small setups that did really well, but they require more consistency, more observation, and more frequent adjustments to stay balanced, one exception I've noticed is shrimp tanks, I've kept cherry shrimp in very small tanks without any issues, and the plants always stayed healthy, I think it's because shrimp breed quickly, eat leftover food and algae and basically help maintain the system for you, they might not be the best algae eaters individually, but when you have a whole colony, they make a big difference, so if you're new to the hobby and want an easier start, go bigger, the more water you have, the more stable your aquarium will be. Before you start stocking rocks or placing wood, plan where your equipment will go, I know it sounds obvious, but trust me, I've skipped this step more than once, and every time it's been frustrating, I'll have this great idea for a layout, build the whole hardscape exactly how I imagined it, and then realize I forgot to leave space for the heater, the lily pipes, or the skimmer, it's such a pain when it happens, you either have to break apart your design, or worse, try to squeeze the equipment in, in awkward spots that ruin the flow of the aquascape, and once you add water, forget about it, moving things around gets a lot harder, equipment might not be the pretty part of aquascaping, but it still needs to blend into the design, lily pipes should be placed where they can move water evenly across the tank, skimmers should be near the surface flow, and heaters, well, they are best hidden behind plants or rocks, but you still need access to them. One trick that helps is to temporarily place all your equipment before you glue or fix the hardscape together, this way you can make sure everything fits, nothing blocks the flow, and it still looks natural once the tank is filled, you don't want to finish your dream layout only to realize there's no place for the filter outlet, take that extra 10 minutes to plan ahead, it'll save you a lot of frustration later, every small detail counts when you're building an aquascape, and if you've made any of these mistakes before, let me know in the comments, I'd love to hear how you fix them.
