water change

Hello, all! New here. I had a 70G saltwater aquarium years ago in middle/high school, and my partner and I recently set up a 108 gallon Fiji Cube. We started a fishless cycle 8 days ago with Dr. Tim’s Nitrifying Bacteria and dosed ammonia twice over the last week according to instruction, which...

Hey so I prepared to do my first water change to my 40 gal and had already mixed the salt in the buckets then I had an emergency which led to the mixed water sitting in the covered bucket for a week and a half uncirculated, Is it still okay to use? (l'm using pro reef sea salt)

Hey need some help. I have a 15 gallon innovative marine tank filled with a few corals and bubble tips. Now my tank is also filled with hair algae I’ve been battle for awhile. Thursday I removed a good amount of hair algae basically half still got a lot to remove. I had to do a 4-5 gallon water...

To the random YouTuber that turned me on to this gadget, me and my back owe you a thousand thanks!!!! Amazon

Have u ever done an ICP test? I have never done an ICP test in three yrs now and I have had things like rusty hose clamps to sea hares dying and going into my wave maker, and still have what I would call a successful mixed reef tank. I may be extremely lucky... How many others r like myself in...

So I started my tank with Fritz because it came free from saltwateraquarium lol but then I had some left over Red Sea blue bucket so I’m trying to burn through that one. During this process I realized I really don’t like Red Sea it leaves behind a nasty brown film. Sooo I’m tempted to just go...

Here is a very well-maintained 7-stage RODI system with dual membranes. This series includes a sediment filter, two carbon filters, a mixed bed, a Cation, an Anion, and a monster Chloramine filter (20") that will make water in the Los Angeles area good enough to grow acropora - it was for me...

Just wanted to see some of your guys mixing stations for some inspiration. I just got some room opened up in the basement and I think it would be a good spot for it. I was thinking about 50 gallon water containers. Also would be nice to have a pump strong enough to push water up to the first...

One of my FOWLR tanks has still not needed a water change ever since I set it up ~4 months ago. Nitrates will not go above 18ppm and since this is a FOWLR I was going to start doing water changes once they hit 30. After all this time it still has still been in the 13-18ppm range. I know for a...

Biocube 32 Gallon - no skimmer just media, mechanical and chemical filters in the back chamber — Everytime I do a water change, the water shifts the sand around and there’s always a bunch of little particles floating around. FYI I do vacuum my sand once a week. Am I doing something wrong...

Works great. Just took it off my tank. Has a stand to keep pump upright 120 shipped 100 pick up in 95121 san jose , ca

Hi everyone, Basically I left testing for 2 weeks and had a mag/cal and alk drop so I’ve just fixed that then i was looking and in the last 2 days one of my clowns disappeared fully with no trace, (the tanks only 4 months old) so I moved all the rocks looking for him, now my phosphate has gone...

Hi all I have a 100lt/20gal AIO tank. It is 1.5 years old. I have two clownfish and a few corals. I run a Redsea ato (worst purchase ever) and I have a Redsea 4head dose. I cannot get my phosphate or nitrate above 0.01-0.02 doing weekly 10% water changes. So I have this ugly brown algae, that...

Looking for input on an idea I’ve been using. My nutrients are usually high and the fleece roller, skimmer, and reactors are all working overtime. Today I overloaded the skimmer and took the overflow out when doing a water change. Added water back normally downstream. Are there any...

Can anyone please tell me what is going on here? Do I need to try to vacuum the things out? I also see some copepods hanging out with them. Please let me know cause my water changes this weekend. Do I need to do a heavy vacuum or just water change. I believe my clowns have been eating them...

Good morning! A few days ago I tested my tank and it was perfect. I had two clowns, 2 scarlet hermits, and a blue long goby (can’t remember the actual name). I went to the fish store the next day early (had tested night before) and I bought two snails, and another scarlet hermit. I happened to...

Keep having a lot of detritus staying and sitting on the live rock. Any time i try moving the rocks all that detritus floats into the water column and back into the rocks. I know dead detritus on live rock can be both bad for nitrates but beneficial for bio media on the rocks as well. Only...

Hey Reef Keepers, Wondering does anyone accurately measure their output and input when they do a water change? I’m thinking about connecting a flow meter of sorts to my plumbing so I can pull out say 38 litres and replace it with the exact same amount. I always estimate it and while I’m sure...

I clean the top of my substrate every two weeks or so, but I never really messed with the bottom part since I read it can be detrimental. It was getting bother by always having to clean algae off the top of substrate (it doesn’t appear everywhere, just some areas), and decided to put a lantern...

I recently installed a 160 gallon aquarium into the wall of my home. Or actually I build a fake wall around the aquarium which was next to the real exterior wall for the house. I was tired of performing onerous and messy water changes so I came up with a system to make them easier. I’ve been...

Pick up Huntington NY Has a external pump, 2x 100 gallon poly containers. I will give you the pvc but would 100% replace it. You could cut the unions out and use them, but personally I would replace. $300 firm, pick up only.

Hello Everybody, I am new to the Saltwater world and I thoroughly enjoy reading all of the forums and hearing the input and advice. One thing I have been trying to do research in now that I have started getting corals up and running is maintaining nutrients. Do you guys recommend consistent...

So today when I was cleaning my tank, I noticed something "different" inside my new maxima clam.... My new clam is mostly blue/teal and I noticed some yellows inside the intake siphon. I have a striped blenny and at first I panicked thinking my blenny barged his way inside... I got out my top...

I am currently working on a project where I have built my own peristaltic pump that I want to use for an ATO and water change system. I'm planning on doing all this with the single pump where it will remove 1 gallon, fill 1 gallon of fresh salt water, then switch to an ATO mode where it pulls...

Hi reefers, I'm a fairly new reefer. Been in the hobby for almost a year. A couple of weeks ago I did a 10 gallon water change in my 69 gallon AIO tank and it went all downhill from there. 1 chalice coral and 3 torch coral have died and I'm trying to prevent anymore from following. I did a...
