Hello everyone! I am 3 weeks into my 55 gallon tank cycle and I just moved my over the tank filter to move it the right a little bit and out flew all this white fluffy/stringy stuff and it’s all over my tank! Is this good bacteria or is this bad? I just added two Clownfish in today. Salinity -...

I am fairly new to this whole salt water hobby but am wanting to find myself a perfect permeant tank to keep growing over the years. But after wanting an upgrade and started to do my research I have gotten myself caught up in what tank to buy, what light to use, what protein skimmer to get, and...

Hi everyone. I recently started a 40 gallon breeder and it was going fantastic. My corals were doing great as well. Then it all went downhill and even my torch died which was heartbreaking. I use an AI Prime light with a self made all in one with filter floss, filter sponge, the balls for...

I’m a beginner to marine and look forward to learning and enjoying the hobby. I have kept cold water and tropical for many years, this is the first time I’m doing saltwater. I feel like a bit of a cheat on the build thread as the tank has been going for a little over 3 weeks now. Setup Fluval...

Hi i added this coral about 3 weeks ago. Not sure if its expanding or dying. New to the hobby and any pointers would be greatly appreciated! Thanks for your time!

My 300 gallon / 1.100 liter drop-off display tank was in the living room, and now we remodeled the house and ended in the hall. Allowing a complete restart. Despite losing the peninsula feel, where the tank was initially build for, I do think the new place is ok, And now 4 months running and...

I was trying to find out what part of the world the Marine aquarium/Marine fishkeeping hobby is most popular but I couldn't really find anything definitive. My guess would be the USA, or Australia but it's only a guess. I was just wondering what countries are most developed into the hobby, I...

Hello everyone, I am two months into my first saltwater experience. I have been doing freshwater for over 10 years and wish I would have started saltwater earlier. My first tank is a fluval evo 13.5 and so far it is doing well, a lot to learn and research. Just wanted to say hello and thanks...

So I noticed my blenny occasionally has a very bloated stomach, I'm not sure if it is related to this bubble he has on his fin, the bubble has gotten smaller so I took him out of QT but now seeing this inflamed stomach I'm not sure what I should do. It doesn't look like this all the time, but it...

This is a photo of my tank .i want honest opinions on the aquascaping. I like it but its so different from everything i see. Is there a reason others dont do a similar aquascape or is it just ugly to others. Its about 5 months old. Im obsessed and loving the hobby but something in my tank is...

Hi all, Thanks for taking the time to view this. Firstly I have done some searching on this forum at PICO tanks and will continue to do research before committing. However... As this is my first SW tank I am open to all ideas and thoughts. I have OCD so the aesthetics need to be minimal, for...

Hi all, Welcome and thanks for reading. Whilst I am not a "newbie" to fish tanks it has been about 3 years since I filled a tank up. However... never an SW tank! Always been a vision but not reality. Upon clearing out my garage yesterday I found my old Fluval Chi 19L 5 Gallon Fishtank. I...
