I just set up my first fish tank about 2 weeks ago. I added fish to it 10 days ago. I tested the water. It is low in ammonia, nitrates and nitrites, but relatively high in minerals like copper and iron. I had planned to do my first water change tomorrow, but now I’m not sure if that’s such a...

My 100L Tank has a PH of 6, at least this is what it reads when testing (using API Master Test Kit). I was wondering if I should go about trying to raise the PH and if so, what the best way to go about doing this is?

Last week I had surgery on my left hand (12/15), and my follow up appointment is Jan 3rd. I have a splint all wrapped up and can't get it wet OR lift more than the weight of a cup of coffee (they didn't tell me what SIZE coffee!). Here's the thing... my two little betta tanks are getting algae...

Hi guys, I have two cichlids (Along with two armored carfish who aren't causing problems) and they are showing major agression towards eachother. It started as the yellow one being the boss (there was a larger blue one that died due to nematodes and all have since been treated), and now they've...

Good afternoon! I am going on almost two months of being a fish owner. I hear different advice on the frequency/amount of water changes necessary for a tank. Because I hear so many different suggestions I’m curious what everyone else does for their tank and how it works for them! I currently...

Hey everyone, First time fish keeper, doing a fish-in cycle using Seachem stability & API quick start. I'm doing 20-30% water changes whenever the water parameters need it, but can't really get into the substrate with my gravel vac without disturbing the good bacteria. That's the problem -...

I was doing a water change when I noticed one of my platy fry in the bucket. I had already dumped out most of the water. I probably didn't notice him at first because water isn't the only thing that gets sucked out (Gunk, fish poop, my sand if I'm not careful). Since the bucket was nearly empty...

I had three tiger barbs in my ten gallon one of them was trying to become alpha it seems and was attacking one of the other tiger barbs so I removed the aggressive tiger barb and put him in another tank and then the next day I come home from work and the fish that was attacked by the aggressive...

Hi guys, I'm going out for 2 weeks starting in mid-August. I have nobody close enough that I can leave feeding to, and after last year's experience and reading, I've decided that, most likely; I'll just leave the fish without food. So, here's where I am: I I've started to ramp up feeding to...

Sigh. Just an update on the water situation. From left to right: Off the tap Filtered (brita jug) Off my 10g tank Can't wait to get my RO system installed, water changes have become a royal PITA for the past couple of months

I realized that I haven't been cleaning the tank properly, but was only concerned when my corydoras started dying off. I was doing water changes with cups (but I did add water conditioner). I would set a reminder to do it every two weeks. I want to get a siphon but I'm afraid I could...

I have a 55gallon tank that has been established for over a year. I decided Saturday to redecorate. Added new gravel, plants and decor. Everything was rinsed. I done a 50% water change also. I left the fish in the tank. I couldn't catch them, so to avoid stressing them anymore I left them alone...

Hello, As you’ve read; I’m now keen to take the shift into introducing rainwater into my water changes for my 200l freshwater planted tank. I live in a very hard water area. The GH (20) and KH (16) are way over the comfortable limit. Would greatly appreciate any feedback on my plan here: -...

For well over a year iv been battling no3 in small amounts usually around 20-40ppm after a 7 period , iv been really trying to eliminate the small factors which can contribute to what I call sleeper nitrate ( dirty filter , pockets of detritus , over feeding etc . Last week I added a peace...

Setting up a new tank and I put some rocks and filter media from my other tanks in to help cycle but I just realized that even though I've always done it this way does the chlorine kill my beneficial bacteria? I always put tap water in and then conditioner in after I fill the water up.

Does anyone have any experience of the relatively new API Aqua Essential, in particular its claims of reducing nitrate? It seems to be their answer to Seachem Prime, as an all in one dechlorinator and ammonia/nitrite "detoxifier" but with the added claim of actually "removing" nitrates. My tap...

long story short - I was wondering if you guys could help. I have a new tank with fish they were doing fine I then test for ammonia yesterday. The ammonia was high, come to find out it was rocks that we separated and separately test and each had ammonia. I did a water change last night the ph...

i made a post last night about how my betta is breathing heavily and pacing after doing a water change. today he isn’t pacing as much but still seems to be breathing heavy. i just tested the water and the ph looks like it’s around 8 - 8.2. yikes! is this what’s causing his behavior? how should i...

i got my very first betta, harry, two weeks ago today. today i did his first water change and took out about half of the water and replaced it with conditioned water (tried to keep it about 80 degrees.) i didn’t notice him doing this immediately after the change, but recently he’s being darting...

I just heard from a friend that our town has really bad water, and when she had a tank, she only used store water and added hardness. We get this pink stuff that collects in the shower. She said it's actually a form of bacteria. I have been treating my water with Prime and then for PH with...

I've read mixed things on if you're supposed to do water changes or not during cycling. My ammonia level is about 8ppm nitrite I would say is between 0 and .25ppm and no Nitrate is id about 20 ppm. I have 2 live plants in there if that helps. And im supposed to be doing anything to my tank or...

After a little help here, as I'm non-plussed. I'm mid-fishless cycle with a 450l (120 us gallon) tank and my nitrite readings are making no sense to me. I started with adding Dr Tim's ammonia a couple of weeks ago, plus "one and only" bacteria. I know there are mixed views on whether it does...

Hello everyone, I’ve been an aquarium owner for over a year now and have an RODI setup with a storage tank for the water. I used to bucket/pitcher it in for every water change but I think it’s time to upgrade. I do realize I could hook it up to the tap and use water conditioner but that would...

My sister has a freshwater tank and was wanting to treat her betta who has finrot so I recommended aquarium salt in a water change. Unfortunately in the water change she forgot to include the stress coat water conditioner. This means she put in a water change of unconditioned water treated with...

Hello everyone, I was doing a water change today when I noticed this insect-like thing on the bottom of the tank. I immediately scooped it up and got rid of it. I also found one exactly like it around a month ago. Does anyone know what this is, and if it's bad for the aquarium? Thanks! FYI...

Due to my disability I rarely do water changes but pay a good friend to do them for me. She's awesome. But she is out sick with a bad pulled tooth and 5 stiches so I have to start some of my water changes myself (it takes me about 4 hours - she can do it in 1 1/2 hours). We typically do a...

Hi, I'm new to the hobby. I currently have living in my 20 gallon hexagaon tank: 3 gourami, 2 zebra loaches, 2 guppies, 5 tetras, 1 snail, maybe 2 shrimp but they're hard to find. So I have Ich in my tank and it's on everyone except the loaches. One of the guppies presented with tail rot today...

My guppy tanks have has this cloudy film in them for the past week. In my adult tank it was everywhere. I just set up this 5 gallon for my fry and after going to sleep I wake up to this. Half of my fry are dead and this milky layer is just sitting at the bottom of my tank.

So as the title saids, 20% daily water changes and substrate clean Vs 75% weekly and substrate clean? Thoughts? @Colin_T

I recently switched my 29 gal long to black sand (imagitarium) and I’ve been cleaning it with a regular siphone, but it’s pretty inefficient. The siphon doesn’t pick up all of the debris and it drains water too fast to get it clean, I’ve tried to stop the flow in order to slow the draining, but...

Hey my tank is a bit of a hectic fish in cycle case. I've been doing 75% water changes the last 4 days and measurements. A Platy has started having fry. Should I wait until she's finished to do a water change? How will I know she's finished? I managed to get two fry into incubation box...

Hey guys my normal method to do water changes is to put water in a container, dechlorinate it and leave it 12 hours before I use it. I heard people do another method which is put chlorine water in and dechlorinate in the tank. Is this method safe and can I use this method for big water changes...

Request Help Tank size: 100L/26gal pH: 7.2-7.4 ammonia: 0 nitrite: 0 nitrate: 20ppm gH: 150 ppm tank temp: 28 degree Celsius (previously 26 but have upped since fish started getting sick) Volume and Frequency of water changes: Normal routine 1-2 per week 25-50% - treat with prime and stress...

I'm having a problem with algea wafers creating so much waste in my gravel. Today I cleaned all the gravel out and did 75% water change. I still had algea wafer waste hanging about the bottom of the tank though, I didn't know what to do as didn't want to risk removing anymore water. So I've had...

Hi, This is my first post on this forum so I hope Im making it in the right category, if not, sorry in advance. Basically I have 200l tank with tripical fish and Im making partial water changes every 7-10 days, usually 35-50l. Before when I had 60l tank every time I was buying 5l btls of water...

Tank Inhabitants: 2 baby blue shrimp, nerite snail, mystery snail Temp: 1 heater set to 86 deg F Size: 10 gallons added a few cholla wood pieces (x3) and it totally clouded my tank, including these levels: added a carbon pack, but I’m waiting on an air pump for a medium-sized sponge filter

First post here guys. I've had the tank on the right for a good while now 8 months. Seems to be well established. I have 10 guppy's, 1 male Betta and God knows how many cherry shrimp. Everyone seems to get along just fine. But I've had this persistent cloudy grey water for 2/3months. Comes and...

Hi, it would be nice if people could share how they do their water change especially on a bigger tank. I am searching for a way to do big water change in my 50 gallon other than a bucket and a siphon because it is very long..

I will be doing a full Masterkit test of the water today, I know the ammonia will be high so no shrimps as yet. On day 4 should I do a water change? and if so how much 50%?
