new tank advice

Hey everybody. I found metal shavings, or what I think are metal shavings in my substrate. The magnet fell onto the substrate which it does often and when I pull it out, I found metal shavings or what I think are metal shavings stuck to the magnet. The system is about two weeks old and I put...

Hello, It’s time for me to upgrade and change my fish tank. I don’t have it too long but i realised fast that sump is way better than filter. Im looking at Red Sea Reefer G2+ 300 or Aquaone Reefsys 434 Marine Aquarium. I live in Ireland and I can’t find here anything else. Any opinion will be...

I am wanting to convert my 90g African cichlid tank to a reef tank, but I am a complete newbie to marine fish and would just like a bit of answers. My general idea for the tank so far would be 2-4 clownfish a flame angelfish and a pair of mandarins but have heard they are difficult to keep so...

Hello!! I currently have a biocube 32 that I would really like to do macro algae in. I currently just have rock and some artificial decor. However I am nervous about macro algae crashing? I know that caulerpa is the one known for going sexual, but I can't find a straightforward answer...

Hi everyone. So I started my tank 3 weeks ago and started off with Dr Tim’s one and only. 5 days later I added 2 clown fish, then a week later 2 hermit crabs. I’ve been testing waters every day to keep an eye. My ammonia has gone up to about 1.5 at the most. I dose Prime and Stability every...

Hello Everyone! Very new to saltwater reef aquariums, but quickly upgraded for 40 gallon tank with very basic system, added 20 gallon QT and 50 gallon DT. Now I’m super excited to build a full system with sumo tank. It is a AIO but I am adding a 40 gallon sump for more volume and better...

I have a 55 gallon tank that just finished its nitrogen cycle. I am planning to add 7-8 fish as the total amount eventually. I've heard people say to add 1-2 fish every 2 weeks to ease the bioload, but is it still 1-2 fish every 2 weeks for a 55 gallon tank? I was planning on getting 2 clownfish...

Hello.My name is Raz and I am thinking on starting the saltwater journey.I have a small experience with fresh water over the years but zero salt.Right now I try to figure out if is worth paying 450€ for 80/45/45 aquarium build or just go for a SUNSUN 90/45/45 at 160€.The only problem is that I...

IM BACK! Late 2020 I sold my home and tank in NY and moved at VA in search for a better life. I don't have many hobbies so Ive been counting the days until I could get another tank. Through my reefing career I've had a 150, 50, and 29 Gallon reef tank each one was better than the last but had...

This is currently what my tank looks like Question 1) the brown algae -read a lot about it being good, but how much is to much? I also have green algae on my glass. Question 2) close up of rocks with micro bubbles - is this okay? Question 3) should I be running lights on a normal day/night...

Hello all! Saltwater fish / coral have always fascinated me since I was a child. Growing up and moving around a few times I kept several 55g long/tall freshwater tanks and it was pretty fun. I am in the military and move around every so often, so I always thought saltwater was an...

Hey guys new tank set up here, i got a Waterbox 15 peninsula. So far the water has been cycling for 3 days straight, i have had a couple days already where i had to add some water because the pump was running dry. I am assuming that it is evaporating? either way the water is staying clear and...

I recently set up a 15-gallon bare bottom tank using media and rocks with coral from my established tank. I have a single lightning clownfish and I decided to bring over the anemone from the old tank to the new tank. The coral is doing great, and so was the anemone at first. For the past few...

Any suggestion for mangrove alternatives? My wife would like to add some green into the tank like below, however my tank is too deep (40cm) and my sand is too swallow to grow a mangrove here. Also, it is difficult to buy mangrove in HK LFS. Any alternatives? I think of some macroalgae, but I...

My alkalinity is staying at 7 with Red Sea coral pro salt as my mix. What’s my next move? To preface this a little, I’ve been reefing for 6 or 7 years but don’t have much experience with a dry rock and sand start. The tank has been wet for about two months I think. Nitrogen cycle was done with...

I’ve already got a build thread on here but I’m making a new one since this is a new tank! It’s a BioCube 16 LED and I got it completely dry, with nothing but the tank, pump, and a couple unopened filter cartridges. I did not know it was a used tank, but it is, and I found out after the fact -...

So I'm looking to get back into the hobby (after 15 years away, had a small reef tank in college...finally have a house to dedicate to a big tank) and have been doing a lot reading and one thing that stood out to me is 1) Live rock is hard to get nowadays and is expensive and has issues with...

Hey! I finally am on my way to setting up a NEW TANK!! i have a 16g BioCube LED, which I thought was brand new, but now I’m seeing it’s been used. It’s been drained, vacuumed and wiped out but I’m currently running it full with no heater, no filtration in it, just the pump with water and some...

As title stated, I’m upgrading to a bigger a45g to a 90g tank and I’m planning to move all my corals and fish and some of my rocks. Is there any risk I should know about ? What’s best method I should follow ? Also to note I will add some more dry rock. Do I still have to do a full cycle ? Can I...

Hello, I'm currently on day 13 of Dr. Tim's cycle and have been following his schedule for starting my cycle. I've dosed his ammonium chloride on his designated days, and dosed my 200 gallon tank with his One and Only on day 1 and another day on day 10 after email dissuasions with his team. My...

Question for my fellow reefers. The picture is of my first reef tank at a year old. It is a 40 gallon breeder build. If is really growing and at this point doesn’t have many problems. I would like to connect a 120 gallon tank I have in my basement to this tank. It has only been running a...
