Hey everyone I’ve been in the hobby for the Past 3 years and have been using mainly canister filters and AIO DIY filtration on my tanks. My last tank was a 125 standard Aqueon that Cracked while i was doing some maintenance ( don’t ask). Now I just bought my first tank with a sump. I opted for a...

I'm lower prices in hopes of making some sales to help cover some medical bills. Past couple of weeks I've been dealing with a sudden medical emergency so apologies if I missed anyone's inquiries. I'm open to offers and will be progressively updating. Please serious buyers and inquiries only...

Modular marine 1800 gph I used on my 250 gallon tank before I ordered a new tank comes with everything you need even the template with the glass bit. The overflow box comes with 1 1/2 drains I reduced it to 1in and had 2 return pumps and it ran silent. If you want to go back to 1 1/2 you'll need...

Need an extra large overflow box. Need large acrylic sump Thanks

Hi all. Looking to buy a frag tank. A lot of corals in my tank are starting to get big and need to frag them soon. Hoping to not break the bank with this. Located in northern, central mass and willing to travel within reason. Let me know. Thank you. Dan

Will be building a rack system shortly that will hold about 15 10 gallon tanks and I have never done anything like it before. I was online looking at videos to get some inspiration and saw this idea for overflow plumbing. Its not hard plumbed PVC but rather vinyl tubing that loosely falls into a...

90 gal marineland aquarium predrilled for sump with corner overflow. Only 2 years old bought brand new. Includes complete setup with eshopps sump filtration, led marineland white and blue digital lights, glass lids, protein skimmer, kessil sump light, multiple heaters, digital return pump...

Hello everyone, I love my reef tank but absolutely hate the overflow placement. (Pic attached below) It seems that the overflow itself is just attached via silicone to the glass wall and floor. I am considering plugging the two drilled holes at the bottom and purchasing an overflow kit that...

I have just completed the daunting task of drilling 2 holes in my 30G. Consists of two 3/4 inch bulkheads that lead to two 5/8 inch hoses. Connected everything to the sump and turned everything on. After adjusting everything to make sure the water level is just right I am hearing intermittent...

Hello everyone, I need some guidance here. I have a 30G DT with a 10G Sump I have just finished setting up. I was going to use a HOB overflow but have heard horror stories and with my work schedule I DO NOT want to risk a flood. So I will be pulling most of the water out my tank and moving live...

I have a brand new eshopps M overflow in box for sale, I can't use it my tank is tempered glass. Asking $100

After reading a bunch of reviews, I'm going to be plumbing my overflow Bean Animal style. Problem is there are so many pics and opinions on how. Please look at the attached pics and give an opinion on the proper design. Thank you

Do I need to support the plumbing coming from the overflow? I’m doing bean animal so there are a lot of pvc. But it coming straight down and forward.

Eshoppes over flow box just trickling. Any advice.

Hi! I am new to salt water tanks and I have just recently gotten a 75g display tank with a 29g sump. My tank is not drilled yet (that is something that I will be doing soon). My biggest question is do I need to match the GPH being drained and the GPH of the return pump? I know that I shouldn't...

so I’ve had this tank over a year. Always struggled keeping coral and maintaining water quality. it’s only 60L and exactly the same as the Fluval Evo except slightly taller + a filter grid at bottom (see pic) I’ve noticed a surface biofilm problem despite good agitation, and my filter floss on...

So Im new to owning a sump and when i first set it up the flow was PERFECT then after a month it randomly decided to stop matching eachother (a fish got in the overflow and it started acting funny and now i cant get it corrected). Im not too fond of sumps to be honest but the water is returning...

So I have a green chromis stuck in my overflow and no matter what i cant net him because hes so fast, anyone know how to get him out??

I’m working on finishing the plumbing on my tank and was hoping for some advice on the return line outlets. I dual have 1 inch return lines each on a separate pump. I want to have minimal plumbing in the tank and was planning on just using the bulkheads without any additional nozzles/loc...

Hello all! I just bought a used system off someone and have been trying to get it all up and running over the last few days. Today I was finally able plug in the return pump and try to dial in the overflow, but holy cow was it super loud. Like loud to the point that I woul get rid of the tank...

Good morning. I've tried to gain insight from other posts but I think I'm still missing some key insights to solve my problem. Bottomline: Noisy overflow and noisy sucking sounds from my tuning holes (see below). Inability to suitably tune the water height in the side sump to make the noise...

I just purchased this tank and setup, I believe it to be a marineland 90 gallon corner-flo. There should be a front panel on the overflow, it was removed for some reason by the previous owner. Does this panel serve a legitimate use? Has anyone had any luck on finding a replacement; I have...

Hello I ordered a Aqua lifter pump to add to my overflow, and I just found out that it won’t be coming. I picked this pump because it was the only one that I have heard of being used the way I am trying to. I’m planning on using it to remove the air bubbles from my overflow and keep the siphon...

What’s up reef2reef I took a little break for a while but I’m back!! So my next project is too hopefully set up a sump for my 29 gallon tank. First thing I don’t want to drill my tank so I am planning on buying a overflow the one I am interested in is the PF-300 overflow perfect for my nano...
