![]() ![]() Thinking of upgrading his current tank we bought as his Grow-Out, I started searching for a ready made tank and was unable to get one in my city after searching for many weeks. Obviously I would have like a house with a pond, which may be for future!ĭecision to go for a 220G: We have an Asian Arowana, we call him Flash (My dedicated THREAD) and it was his 2 year anniversary with us. Given the constraints where I live, wrt the construction of the multi-storied apartments, size of the house, space in living room and availability of materials and the frequent movement of house that may be needed related to work, this was the max size that we could go with currently. Preamble: It is a 220 G aquarium tank, and not in the league of many other tank many of the members in this forum have. I can send you actually measurements of the standpipes as well as links to the parts I used.My 220G Aquarium Tank Build with Bean Animal Overflow and Sump: The red circle shows the small air vent hole drilled in the top of the secondary line.įinally, if you choose to use my set up. The red line indicates correct water level I've used this set up and was able to adjust to flows from 600 to 1800 gph. the main line does 90% of the work, secondary line does 10% and emergency hopefully is never needed. never allow it to go over the air vent hole or it will over siphon. then close it a bit more until the level stabilizes to the center of the secondary line. this will force it into full siphon mode. Also since none of the parts pictured are not glued, just press fit you can take them out for cleaning (or taking a picture for a fellow hobbyist).įor tuning the system once installed, pump running and gate valve wide open, begin closing the valve until the water rises above the main drain line. in order to get them to fit in the eshopps box you will need to use whats called "street elbows" which makes them shorter lengths. I do suggest doing the down turn lines for optimum quietness. Yes, those lengths are optimum for the eshopps eclipse L box. then starts over again, filling the overflow until it's forced into full siphon mode again and repeats. if the main line is left wide open it will siphon all the water out of the overflow until it draws in air and breaks the siphon. By restricting the flow down on this line will raise the level of the water in the over flow. No, the water level in the overflow is controlled by the gate valve on the the main, full siphon, line. If you have any other questions don't hesitate to reach out! The was very effective. If you're planning to use powerheads that will create a standing wave within the display - please test the overflow with the maximum wave frequency to confirm your siphon is great enough and that it will not overflow and will not cause a crashing noise as the water sloshes through. You don't need to glue anything in the overflows and you can change them whenever you want. My recommendation would be to buy some cheap 1" pipe and cut it to length to find the sweet spot you're looking for. It looks like the Eshopps overflows all use 1" PVC for the drains. It has a lowered box compared to the weir and at high flowrates this creates a very noticeable noise. If they are equal in height the overflow will be truly silent - this is what one of the major complaints of the synergy overflow is. The purpose of making the adjustments is to ensure you have proper water height in the overflow box that matches the water height within the display. The size of your return pump and the flowrate you're looking to achieve with this overflow will really determine what heights these pipes should be at. It looks like you might be overthinking this issue just a tad! The height of the full siphon and trickle drain isn't really a specific height as long as they function correctly. There’s also an infographic stating that the height between the emergency and primary should be at least 6”. You see differing opinions on if the secondary needs to be higher than the primary or if they can be the same height. I’m uncertain of the correlation between the height of the primary and secondary drains. The red tube is what came with the box, but I’m thinking that it may be too short because that also means that the primary and secondary drains have to be shorter yet. View attachment I saw a thread over on R2R where you helped someone with the appropriate heights of each drain. The external box is right under the top brace. I’m using the same model as what we had before, an eShopps Eclipse L bean animal set up. We didn’t set it up optimally the first time so I want to make sure we get it right this time and not having to do almost daily adjustments to the gate valve on the primary drain. Hey everyone, I’m at the point in my re-build on my 125 gal where I’m doing the overflow box. ![]()
