question

I've been thinking about interesting tank options, and one of the thinks I think could be interesting would be a lid that's fitted in the tank so that the bottom of the lid is just below the water level; so you'd see through glass on the top-side as well. You'd need to figure out an easy way to...

I am currently in the process of starting my first saltwater aquarium which is a 120 gallon FOWLR. Yesterday I got my first fish, a banggai cardinalfish. It is currently in my 10 gallon QT tank before it will go in the display. Since I got it yesterday, it has been hiding in the corner of the...

Hello everyone, I would love the opportunity to pick your brains a bit. So I am in the process upgrading from a 54 gallon corner tank to a 125 gallon I bought off of Facebook. (Pictures to follow).

I was wondering if anyones had success using a dab of silicon on their suction cups? I know magnets are prefered, but I just don't have that options ATM. Would love to hear people's experiences. Thanks!

I have a question.. when someone asks you what you’re hobbies/interests are, what do you say? I always say something like “fish keeping or I keep fish tanks” but they always look confused like they just don’t get it lol. So I’m just wondering if there’s a better way to word it? And what do you...

Hey All! Just a quick question (If I can make it make sense!). I've started a phytoplankton culture in a 1 gallon jar (128 ounces, or ~3.78 Liters). I started the culture with 1/2 gallon salt water (64 ounces or ~1.89 liters) and 16 ounces of Phytoplankton. Once the phytoplankton is ready to...

I have a very curious question. Would my bumblebee snails (that I got to get rid of vermetid snails) would those harm my Tridacna derasa clam? or leave it alone? I have 1 bumblebee snail. Thanks so much!

Hey Everyone, so I’m usually bored at work and I always think about the future reef aquarium I want, when I have my own house and settle down etc. I know I want a 250 gal plus reef but I always think about how I would put together a tank of that size. On one hand the Red Sea and water boxes are...

Just wanted to know, asking for a friend :P

I’ve always wondered why every time I clean my aquarium, when I pour the new water after siphoning, my fish always swim towards it? Maybe it has something to do with oxygenation? My filter is pretty big for the tank size but I find it weird that even though fish are scared by strong currents of...

I have an very established 180 gal mostly Lps tank,and for example I have my alk dosing every other day 24 ml four times and 17 ml once, spaced from 7pm-2am. If I was to change my dosing pump to dose everyday with those same amounts just cut in half, would it swing my chemistry and cause...

We all have that one coral that has lately caught their eye, whether as a future planned acquisition or a photo that made you look twice and wonder how you can incorporate that coral into your ecosystem. For me, I want to attempt a classic easy acro once my mixed reef starts taking off - Garf...

Could adding top off water affect the salinity enough to shock sea urchins? I assume no, since i have a few asterina stars that are fine with it but those are also very hardy so I wanted to make sure. Thinking about getting a tuxedo sea urchin since I like them so much.

So I have a 90 gallon saltwater tank. I’m using a external overflow. It’s getting old and there is two cracks forming on each side of it and I’m afraid one day it’s just going to give out. My 90 gallon tank has a hole drilled on it. It has a bulkhead installed it’s about 6 inches from the top on...

Just an interesting thought I had, what qualities would you view as being most important in Reefing? I know its a tough choice, but you can only select your top 3 options in the poll! Will be interesting to see with some data what we view as being most important! Equipment (Quality...

Hi all! I got a maze brain coral recently and I've noticed that it's feeder tentacles are bubbly looking, is this normal or a cause for concern? And if it is what could cause this and is there anything I can do about it?

I want to rearrange my live rock for a couple of reasons. the most important being all of my coral, I want to change it to create better placement for my coral now and future coral. The second being it does not look complete in terms of rock work. This leads me to my question. Is it okay to...

Hello! I am starting a a simple 20 gallon long reef tank (dimension are 30x12x12) and I would like to have an ATO. I have looked at quite a few ATO systems, but with no sump I'm wondering if I could add one? If I add the sensor to the tank will surface agitation mess with the sensor causing it...

Hello! I’m new to the world of fish and I recently got 2 betta fish. My grandma recently bought me a new 10 gallon tank so I decided I’d also put some fish in there. Problem is, I don’t have any pet store near me so my only option is online shopping. I’m thinking of getting fish from...

I’m looking into sea cucumbers, the pink spiney and black and pink cucumbers. The issue is some websites say their care level is easy and others say expert only, so which is true? Anyone have either variety and have any insight?
