Water changes are probably the best time (after feeding) to spend quality time with the aquarium. you aint doin' it right if you aint gettin' your hands wet :) - great vid very informative!

When we say we are fish keepers, we are really saying we change water in our bacteria farms.

I also have something to tell you all...So yesterday morning I was on Facebook marketplace I found a 33 gallon lowboy/long with a Current USA light and everything in the tank... It is an amazing tank and I'm so excited...haha..my husband actually popped up when I showed it to him and said let's go get it.. you're rubbing off on him Jason😂 thank you all for helping me enjoy this hobby so much!♥️( And teaching my husband a few things .. like it's cool to be a bearded man.. who loves fish) He also told me yesterday he enjoys watching me enjoying fish That's pretty cool cuz we've been together thirty years👍😂😁♥️🐟🌿🌱

Hands down.. you always give the best technical advice in the most simplest terms. I'm buying your affiliated test kit too. Keep up the great work and vids!

20-30% every 2 weeks for my 55 and have had no issues. Every other water change involves changing filter media, cleaning any algae, cleaning the rocks, cleaning the gravel, and reorganizing the rock piles. Mixed mbuna/peacock tank. Have 10 fish in there right now. I don't water test and feed once a day. Have had no issues in 10+ years and just keep an eye on the fish and tank conditions.

I had a terrible time with nitrates to the point that I was practically starving my fish and doing 50% water changes every week! Then I tested my tap water. HOLY CRAP!!!! My water out of the tap was testing 60 I was replacing bad water with more bad This needs to be addressed!!!! I watched countless videos before someone actually suggested testing my tap water. We had a whole filter system installed on our home which posed a whole other problem, but no more nitrates! I'd love to see more videos about water coming out of the tap and how to deal with it.

I had a great schedule for our 75g Tanganyka tank 25% once a week until we added 3 multipunk catfish now I've been chasing the nitrates for a couple of months. Going to 3 20 % changes a week trying not to stress out the Calvus. As usual another great video. Thank you.

Tanks' for the info sir. I had a very fine substrate that was very difficult to vacuum so I recently switched over to gravel in a 14 gallon Bio Cube next to my desk. I've had it close to 20 years and love it. I do fresh although it's made for a reef life.

Possibly the best video I’ve seen regarding water changes. Fantastic! 👏👏👏👏

Awesome vid. Thanks guys! I have a sump under a 75g tank, and I change the polyfill in the inlet chamber to the sump frequenty. Each time I do I siphon vac the gravel into the sump inlet chamber, collecting it all there, then change the floss. I can do this in a only few minutes and it gives me a good look into the nooks and crannies in the tank to keep an eye on what's goin' on in there :)

My 30 gal long is scheduled for every two weeks, 5 gal. This is a heavy planted tank.

Great advice! Trouble is the nitrate test kits are a pain to use and very inaccurate. I ended up using TDS as a proxy. Takes seconds to check.

[aquienpuedainteresar]

That Molly tank is beautiful planted. I'm definitely going to the replace plastic plants, hopefully sooner that later. Have to do lots of research

[CichlidCharmer]

Great info! This is the best explanation of when to do a water change that I have been able to find. Thank you!

[zeftlovescats]

Should Still water change if my nitrates are always 5 or less? I'm assuming because I have plants its a good idea to do like 25 percent weekly? 10g.

I have a $10, 10 gallon Petco Tank, heavily planted, a sponge filter, and a very low bio load: 5 guppies, 10 neocardinas. Actually I think the heaviest bio-load is all the bladder snails (that I never bought). I have heard the the little shrimp are even more sensitive to large water changes than most fish. Is that true? My levels of ammonia, etc are all very low, so I do a 10% water change weekly. I only do that because my “black water” tank is a little too black. I’m trying to slowly dilute the tannins just a bit.

You guys are just wonderful. Thank you for the content.

My 40 gallon get a water change every week.i find that it’s a good time to interact with my fish.they know my severum will rub against my hand so I could pet them.
