overflow question

I did a cursory look and could not find a post specific to my problem so here it goes, newbe question: I am building a 200G and the tank has dual internal overflows; each with a 1" and a 3/4" hole. I've been told the tank is an aqueon 220. I've read and watched YT on this but cannot decide if...

Hey Reef2reef community I could really use some knowledge here. I’ve had this 80 gallon rimless setup for about 4 years now and the overflow water level rose by itself a few weeks ago and I can’t diagnose the problem. You can see attached in the pictures where the algae growth is and where I...

I recently purchased a used 90g aquarium that I am trying to clean up and get started. It has in internal overflow with 3 holes drilled in it: two holes are drilled for 3/4" pipe & one (in the middle) is drilled for 1" pipe. It was set up with a herbie overflow before- the two drains were the...

Hi You ALL, I have been reading, watching youtube vids, reading more, watching more videos, day and night, home and at work. Pretty much the last 3 months i have been all about saltwater fish tanks. At first i was looking at buying a 50 gallon tank bc i read that its the best beginner tank...

I am looking into getting a 125 gallon at a really great, hard to pass up price. I’m still fairly new to reef tanks but I understand having a single overflow with no redundancy may not be a great idea. The new tank only has a single overflow, as pictured. Is there a way to convert this to a...

I am working on putting together a new frag system. It will consist of a 40-gallon breeder and a Bashsea Smart Series sump. The sump has three 1.5" drain connections, which is helpful as I intend to use a Bean Animal configuration. However, that is where I need your assistance as I decided to...

I've recently installed a sump and HOB overflow to my system and it has been running flawlessly for about 2 months now. Suddenly today, the water level is extremely high in the display. Another 1/4 inch and it will overflow. I havent adjusted the overflow or return pump at all since it was...

I have a tank that is about 72 inches long and 18 inches wide with two overflow boxes on the back wall with each having a 1 inch hole and a 3/4 inch hole in the bottom of the glass. I have a sump with two 1 inch drain holes that I will most likely be using. My question is how to setup the...
