Hi... Im building an approx 8k litre pond which shall also be used for aquaponics. I have a 75mm bottom drain reduced to 50mm and a 40mm overflow pipe. Unfortunately i notice that the flow to the first drum filter is poor and I end up having more inflow then outflow. Could you please help me out?
Just so we are on the same page. Does your bottom drain go directly to a pump? Then the pump pumps water to the filters? Either way you typically want the outflow to be larger on a gravity feed system. If the water coming in is to much for the gravity feed pipe to handle then it would naturally overflow. So you can either increase the outflow pipe size, get a weaker pump or makes what's called a bypass. This bypass involves a T fitting and 1 or 2 valves. Me making a drawing would be better but otherwise to describe it. Using that T and vales, you would allow your self to reduce the amount of water flowing into the filter, which would help with the overflow issue. The rest of the water will just go directly back into the pond to allow for more circulation. It will eventually cycle through the filter. When making a gravity feed system you always have to take into account the flow rates. Hope that answers your question. If not just elaborate some more so we are on the same page.
@@vonponics thanks. Ive been able to sort it out. Ive used plug the outlets of the filter directly. Onto the sump tank. This allows it to create a siphon and allows for better waterflow ive noticed
I actually got them used on craigslist. However you can find them here: www.theaquaponicsource.com/product-category/grow-beds-media/page/2/ The person I got them from go them form this company.
I thought about something cool you could do with your sump in your next design! Since it's in the ground, and you have that elbow coming off your pump, if you entrain some air into the feed from your pump and enclose the sump tank you could make it into a trompe and get extra free air off of it for other purposes. en.wikipedia.org/wiki/Trompe
everything you say u'll b changing again , moreover the extra outflow from fishtank too directly going to sump without filter isn't it a mistake ? thirdly it is so difficult to catch up the things you telling about changing 2 " to 1 n half inch pipe without telling reason to do so , fourth is you have such clutters and messed up connections which makes difficult to see where is drain outlet as more fittings around it , i think you really need to arrange your set up first n understand things too then make video n guide others
This video was just to show the plumbing set up I had at that time. There is always room for improvements that I why i was saying I will be changing the set up. The extra overflow is not a mistake. It is a legit way to set up plumbing, that is if you want to have a stronger pump and more flow through the actual fish tank. It is generally refereed to as a bypass which allows you more flexibility with pump sizes (gph). It allows for more circulation of water through the fish tank. Yes it would be better to have all the water go directly through the filters. However with a gravity fed system it would require larger plumbing for the outflow from the fish tank and through the filters. Either way, with this set up the water will still end up going through the filters just given time as it circulates through the fish tank and the sump. Sorry if the video was hard to follow. I am still improving and learning how best I can present the information I am saying. That is probably why you can't quit follow what I am saying. If you are familiar with plumbing it should make more sense. I do say things that make sense to me since I know the background information, but might not make sense to you. That is just something I have to learn to present better. For example you mention going from 2 inch pipe to 1 1/2 inch pipe. If we are thinking of the same spot, which is the plumbing going out of the pump. Then I am referring to the fact that the pump has a 2 inch intake and out take already built into the pump itself. But I reduced it to 1 1/2 inch since it was cheaper buying 1 1/2 inch flex pipe than 2 inch flex pipe. I may have a lot of stuff in the green house since I am always doing things and upgrading things, however none of the connections are messed up. I used bushings, elbows, reducers, and etc in the correct way and in the manner that would allow the system to function correctly. Some things could have been done using less connections. But why spend money on more fittings to make it look cleaner, when I already have a good amount of fittings that I got from other people that I can make work. And for me to wait until I have the system completely squared away would not be to beneficial for others. People can learn through my mistakes and through the progress in developing my own aquaponic system. That is the main purpose of my videos, which is for people to gain/ learn something through my progress.

Do you have a link to your black plastic media beds?
I actually got them used on craigslist.

interesting I will check that out.
I was thinking to just put a venturi at the end of the pipe near where the water enters into the fish tank.
