90G Acrylic tank

Hi Y’all

I’m going to start from the beginning.

I was a freshwater guy until my friend invited me to his house, where I saw his reef tank. After that, he convinced me to start my own reef tank. I transformed my 55-gallon freshwater tank into a reef tank, using dry rock that I got secondhand. I didn’t really know what I was doing, so I made my first aquascape and set up the tank without a sump. I used a Fluval canister filter, which wasn’t a bad starting point, and relied on the small amount of knowledge I had gathered from online research and YouTube videos.


After that, my tank got hit with ich and marine velvet. Luckily, I took it as a learning experience and figured out how to quarantine (QT) fish. I treated all my fish, losing only two in the process—which wasn’t bad for my first time quarantining fish.



I definitely didn’t let that stop me from continuing what I started, so I went and got a 90-gallon acrylic tank I just wanted to go bigger because I know later on that’s what I would want.

Here’s the corrected version:


For this tank, I resealed the seams so I wouldn’t have to worry about any leaks. I also sanded and polished all three sides to remove scratches and painted the back black.


This time, I decided to use a sump. I bought an overflow box, drilled a hole, and added a return nozzle.

This is a long one, but after all that, I ended up with copper in my tank. After months of dealing with it without realizing the cause, I sent out an ICP test and got the results—22.0 ppm of copper in my tank.

I decided to throw away the sand and rocks and start fresh. I cleaned everything, created a new aquascape with fresh dry rock and sand, and now the tank is looking really good.

Sorry for the long introduction to this tank—I just wanted to share my experience up to this point.

Oh I think we met at the swap! I recall hearing about your 90. Nice to see you starting a journal!

Do you know how you ended up with copper in your tank? Could it have been the second hand rock?

Also, have you checked to make sure your sump is big enough to handle the back flow if the pump turns off?

Yeah, we did meet—thank you!

I don’t know if I should be sharing this , but I made a dumb mistake—I added a metal valve and forgot to remove it. I actually realized it right after I sent the ICP test, before even getting the results.

It’s definitely not the rocks. I cured them when I first set up the 90G.

As for the sump, I did check, and yes, it’s enough. I made sure to add just enough water so that if the pump turns off, the sump doesn’t overflow.


I know it’s a small sump, but I plan to upgrade it when I get a stand that can accommodate a bigger one. The stand I have now is designed for two tanks, with another tank on the bottom.
 
What’s the footprint?
48”x18?

I see a potential plumbing issue
I see that the 2; 1” drains feed into a single 1”
The 2 should feed into at least a 1.5” line

@Srt4eric
Please confirm

Trust me, you don’t want to have a drain line backup

Trust me- I’ve made worse mistakes when I first started lol. It’s part of the learning process! Having a journal and asking questions here will help you avoid the big ones tho! Lot of smart people on here.

Have you considered building a stand? I built mine out of 2x4s. Relatively easy following the Rocket Engineer plans you can find online. I’ve built my last 3 stands and before that I didn’t even own a drill or any tools lol. Building the frame is easy. It’s more skinning it and painting it that’s more work. I still haven’t built doors for mine but they’ll cover up the front of the frame to hide the 2x4s and stuff

Yeah that’s what I’m going to do is build my own stand I’ve been looking around for ideas and watching YouTube videos.
It seems easy but I also want to make it look nice at least from the outside I already have clear plan on how I want it to look but idk when I’m going to do that.

The stands that you build looks nice some plywood on the front with doors will make it look nice
