gravel

Another newbie question: GRAVEL SHMOO. Keep it there, or somehow remove it? In Feb 2024, I added a layer of standard Seachem flourite under a layer of gravel to Plant Test Tank #1. I haven't touched the substrate since. NOW the substrate looks NASTY underneath. But I get confused...

Hi everyone, I have maintained a small aquarium earlier. I am now planning for a 225-250 litres community tank setup with an over the top Filter. This will have few small size gold fish varieties like the Ryukin Gold and few widow tetra. I will not not be having any Plants. Please help me with...

I know a good amount about OUTDOOR gardening, but am learning about aqua-gardening. Since most of the readily available planted tank substrates either look too silly, come in too large a quantity, or cost a LOT, I'm curious if it MUST be used IF I am already adding a little liquid fertilizer to...

I have a new setup 40 gallon and I was wondering to see if it’s possible to add sand substrate to the gravel I already have in my tank it’s only a few weeks old is this something safe to do I saw a few people on YouTube using plastic water bottles to do it , but my next question would be would...

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...

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

I have brown algae in the gravel only at the front of my tank. I own a bristlenose pleco which seems to help but not entirely remove it, any advice on this? Thanks

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...

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. My hornwort seems to shed needles until there is either nothing left or just a small part covered...

Hi Guys & Gals, So my gravel has arrived it’s been thoroughly rinsed. However I have only added 15kg so far and to me it looks like enough. However when checking the calculators etc it’s saying I need at least 25kg? What do you think? Should I open the other bag or is it enough? Ignore the...

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...

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?

I have 4 Pepper Corydoras in my unheated 29 gallon tank (temperature stays around 72°F). I plan on adding 2 more so they are more comfortable together. Before that though, I had a question about substrate. I have a planted tank gravel in there now with leaf litter covering most of the bottom...

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...

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...

Hi everyone, here’s the questions; 1. Is there anyway to move substrate from gravel to sand without moving any fishes? (Discus tank) 2. does play sand increase pH level? is this dangerous to discus and angel? 3. I always wanted to do Blackwater tank (inspired by @seangee post “back to black”)...

Can anyone tell me. @essjay

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...

Hi, I need some advice on my aquascape substrate. What I want is for there to be gravel in the back and mostly sand in the front. The sand being for my horsehead loaches and cories. Very heavily planted with roots and some rocks. Med-tech. I bought some floredepot, but it's only enough for...

Hey Guys, So i recently tried the idea of doing half sand half gravel tank. Its a 55 gallon tank. I did this for the purpose of my corys. But the thing is now my water is becoming a light green color. Dont get me wrong the front view is amazing. But if you look at the water from the side of the...

Hey all I have some questions about cleaning my tank. I have a heavily planted tank with some S repens and lots of other plants. I change my water and I just can't vacuum my substrate. (seachem flourite).   I can see all the specs of brown crap in there, and especially on the glass of the tank...

So, I just changed to sand from gravel and I must say, my corys seem to love it..   *I just added the sand 1 day ago* *I rinsed out the sand twice before adding it in the tank*   - The sand seem to have two layers in it.... the bottom one seems dark black with no air pockets while top one is...

Don't let the title mislead you, it is my first tank but I have been running it now for just over a year   I have considered putting up images of my tank for a long time now but never thought of it being good enough as I see so many awesome tanks on here, but I figured I could show you where I...

So I have a siphon that I use to go my water changes with. I stick it in the gravel to get the gross stuff out and everything but I've noticed my gravel looks a little dirty (like in coloration as in dirt is stuck to it kind of way). To clean gravel do you just scoop some out and give it a...

So I'm fairly new to tropical fish keeping and have many questions! I've been doing plenty of research but my latest question sits at; How much gravel do I need for my tank? It's 80cm x 30cm and I'm hoping to have 3cm-5cm of quite small gravel. I've been looking at possibly around 15kg if...

Hi all,   I have been performing a fishless cycle on my 25l tank now for 5 days.   Here is the thread covering it, to date, with all water levels and details etc etc.    In a nutshell:   Added a 1/2 dose of tetra safestart then added 3ppm  of ammonia.   The following day the ammonia level was...

Hi I am looking for some cool fish that are good for clean up crew. I have a 20 gallon tank with one gourami and 3 zebra danios. I really want cory catfish but I don't think I can get them because my gravel is not smooth, i think? Post some pictures on this if u can on here of your gravel and...

I'm really considering switching both my tanks to sand after looking at how pretty some tank set up with sand look.   Is sand easier to take care of than gravel?   Do plants grow better in sand or gravel?    Which do you feel is better out of the two?    I figure play sand would probably be my...
