new tank advice

When you are starting up a tank and ready to add fish which ones are you adding in first? I personally like to add any non-aggressive but outgoing fish, then I add in any shy or sensitive species so they have some dither fish to help make them feel more comfortable. Then lastly, I’ll go for any...

I just started this saltwater tank 6 weeks ago first time having saltwater. Firstly, since I started started the tank I noticed some white algae developing. It doesn’t seem to bother my corals but is attaching to Macroalgae. (photos attached) I have a few macros in the tank so I don’t want to...

So I need some advice. I have a 20 innovative marine and I’m currently about to move. Now I was thinking I’ve currently been having different issues with this tank mostly hair algae and minor other things. I have a spare 15 gallon innovative marine tank that I’m going to setup at my new place...

I have been researching PNS Deepcycle and have heard very positive things about the product (https://www.microbiofarm.com/hydrospace-pnsdeepcycle). Given that the shelf life is fairly long, I was wondering if I could put my dry rock in a bag and let it marinate in this solution until I am ready...

I currently have a purple tang, clownfish, mandarin and yellow watchman goby in a 100 gallon. I’m upgrading to a 5ft 130 gallon and would like to add more fish. Would of be best to add the new fish at the same time with my current fish? Would like to add a bristletooth as well. Planning to...

Hello! I have been in the fish keeping hobby for around 4 years at this point (I'm still in highschool). I have had one 20 gallon freshwater tank which I recently had to get rid of to clear room and currently have a 10 gallon saltwater tank running with a Watchman Goby and Candy Cane pistol...

Hello, ive been following forums on here but just created an account, new to reef tanks but have done freshwater for a few years and have a couple large tanks that do very well. Anyways, I have a 75 gallon regular petco tank that is around 2 months old, more like 7 months old though because i...

Hello, setting up a Tideline 21 AIO Nano Reef for the first time in over a decade. Curious, I have the tank, which came with filter sock and return pump, but the middle chamber is empty and has no media basket with it. What do folks put in there nowadays? With no basket I didn’t want to put...

Hey y'all, glad to be here, this is my first post here, and my first tank is a 20-gallon AIO prospective soft coral and clownfish tank. I began the fishless cycle with a seeded sponge from an established tank from work(Clown nursery), as well as a few rocks and water from said tank(No ammonia...

I haven't seen one on the equipment section or any of the other forums. The rip clean sand article is good but I'm surprised there isn't one for all of the points you need to consider when you upgrade/change your tank.

Hello, everyone! I have a 40 gallon that I’ve had running for about 9 months. I’m planning to upgrade to my 55 long that was previously my freshwater tank. I’ve already added my base rock, live sand, and fritz about 3 weeks ago now. My parameters are looking good and my cycle is stable. I’m...

So my 5 gallon tank is now cycled (ammonia , nitrite 0, nitrate 50 ppm) It's got two pieces of live rock and a red grape macroalgae. Now what? Coral? More macroalgae? I don't have a sump, so it's gotta be a "planted" tank

New to the hobby, I've been using api test kit but been seeing lots of people say it's unreliable. What kit would you suggest? And as far as parameters go, what parameters have you guys had luck with with keeping the tank happy. Currently have some snails, sand sifting star, royal Gramma, and...

Just wondering what I should do about my yasha and pistol shrimp. They went in 2 weeks ago and were very active for a day or so. Since then they have gone into hiding. I've not seen the pistol shrimp for about a week and can't hear him snapping. The goby pops his head out every 3 days but only...

Hey there everyone. Thanks for having me. I am new to the site and new to reefing. Always wanted a reef aquarium. I have experience with freshwater. Have kept many african cichlid tanks so I understand the cycling process enough to maintain those tanks. I always would do a fishless cycle to get...

Hi everyone! I am fairly new to saltwater. I've been researching and learning for a couple of years now and finally have my first saltwater tank cycling. I am trying to work on my stocking list. My tank is just a standard 20 gallon long. For filtration I'm currently just running two HOBs, a...

Hey everyone this is my first post. I started my 50 gallon IM lagoon at the end of November. I started testing my alk, calcium, and magnesium on December 23. My alk started about 11.9dkh, my calcium started at around 290ppm, and my magnesium was at 1100ppm. I figured I’d do water changes and see...

hey guys i’m looking to start reefing that last couple months i have been doing some reasearch and have been trying to find what will fit best for me. little bit about me so it might answer questions you have, I have 30+ reptiles and definitely plan on getting more lol so i am sorta limited on...

Allllllrighty then! Brain overload. So, the new 40gal aio is all cycled, 2ppm ammonia to 0 ammonia/0 nitrite in a day. Cool. Now I’ve learned all about QT, and yes will opt for safety and do it. First question is should I continue to dose ammonia occasionally in the DT while new fish are in...

Hey everyone! Just set up my Reefer 170 and was looking for some recommendations on what livestock I should add once the cycle is done!

Hello Reefers, I am setting up my refugium in the middle chamber of my AIO Hello Reef 15G nano tank. The first chamber is a filter sock I will be swapping out for a media caddy. I have two questions: 1) How do I properly light my refugium so I don't get light spill over and what is the...

Ok, so I'm setting up a new fish only 105 litre tank. The tank is filled, I've used dry rock but live sand. After quite a bit of research I decided to do a fish-in cycle using ATM colony bacteria. However, when I got to the LFS the assistant said that I need to cycle my tank for 3-4 weeks...

Hello all! My first post here after lurking for some time! I’ve had a few, small to medium, freshwater tanks growing up, but this will be my first marine tank—and quite a few other firsts too! It’s my first non-rectangular tank, my first time using a sump, and I’m now living in Macau, where...

Tl;dr: I have acquired a new 15 gallon aquarium, this will be replacing a 5 gallon aquarium, but i my only option is a hot swap rather than letting the new tank cycle on its own. Any advice to make this go easier? I'm also curious about media, as it stands in the old tank I've just got a pile...
