I am looking to start a salt water aquarium and have decided that I want to use an IM fusion 20 gal long aquarium. The problem I am running into is what to put it on. I don't think IM has a stand specifically for the tank and I am not finding great options that would hold the tank and hid the...

Hello Reef Buddies! I am new to the reefing hobby for the past year and a half. Started with a 20 gallon long tank and have been cycling a 40 gallon long for the last 8 mos. My 20 gal is now packed with corals, but I wanted to share my progression of the tank, its ups and downs, and maybe get...

Hey guys! I’ve been lurking on r2r for awhile now and this is my first time posting here. I was wondering whether or not a McCoskers flasher wrasse would be compatible/fine in a 20 long? I’ve done a lot of research on this topic up to this point as it is my dream fish and I understand that while...

Hi, I am upgrading from a 20gallon long AIO to a 30gallon long AIO. I was wondering what the protocol on this was, mainly focusing on if I should keep the old sand or not. I have vacuumed the sand for a deep clean the last 2 days, but is it wiser to just use completely new fiji pink in the new...

So I just picked some new Euphyllia and gotta say I feel like I did pretty good. Sort of popped into a store on a whim since I had some spending money and saw pieces I couldn’t pass up. 1 rainbow hammer wall variety. 1 green and purple tip grafted skeleton. 1 green on green frogspawn. 1...

Currently running an Aquaclear 110 with floss, a little tub of miracle mud and Chemipure Blue. This set up worked great for about 8 months until I was on the road for work. Things got out of wack when the ATO switch stopped working and things got bad. Before that even took place I suspected my...

I know it’s bad...feel free to bash me... I’ve had it for about a year and other then replacing the cheap hob carbon filter a few times I really haven’t done any maintenance or testing. Although I do have a ATO and use RODI I buy from the LFS I haven’t even done one water change... I just...

I have a 20 gallon long currently with one clownfish. I plan to get another clown, a firefish, and watchman goby. I put this into a stocking calculator and I have room for one more fish. What are some suggestions? Also, can I add some invertebrates along with that? A serpent sea star or shrimp?

Hi all, I recently set up my first tank and today finally got some coral and fish for the tank. I have the Jebao SOW-8 pump for making waves, but this pump is too strong even on its lowest setting. My little clown fish are unable to swim around because of the waves. Does anyone have any...

Hello, I started my second tank today, a 20g long saltwater tank, and want to dedicate it to a snowflake eel. A lfs has a 4”-6” snowflake eel and was wondering if this sized aquarium would be an okay sized for the eel for about 6 months tops. Gonna be putting up our 90g in the summer sometime...

Hello fellow reefers! So i have decided to start a new tank (not my first or 2nd). I'll be going for the Innovative marine 20 gallon long peninsula all in one tank. So now i have to pick a light fixture that can have full coverage of the tank as i will have it setup in a peninsula style. I...

So i have a 20 gallon long tank that i want to drill on 1 side to make a peninsula tank that would have a 10 gallon sump. Now that being said i don't know how many holes i need, what size holes, and where to drill (top,middle,bottom). I'm not sure if it is even possible to drill on the side...

Introduction Over this build thread I am going to embark on my first ever Saltwater Fish Tank. To be perfectly honest I have never had a successful fish tank; growing up probably like most kids wanted a fish tank and then I simply got bored days later. That being said I really hope it isn’t a...

This might be a no-brainer question to few or most, I am just having a hard time understanding the interaction of these two. I have a 75G DT with 20L sump, the sump is basically set up with a filter sock, water passes through the length of the sump (recently added chaeto to this section, sump...
