Not frequently. let say weekly or biweekly. Have you got any idea Ryan? Well, can you tell me how hight between the bottom of our net pots and the pipe bottom or trough bottom? Should net pot's bottom touch the the bottom of the trough or pipe?

You are right the water should be filtered. But I'm using UVI clarifier and biofilter and settling tank still there is much sludge in the pipes. Anyway I c they don't work well for my system because they are in small sizes, too small to filter the water. I wanna use the bigger filtration as well but the materials are heavy that I'm afraid that my house's roof is not able to stand with them,

Just wanted to add my NFT pipes are about 3-4 feet long and are only raised about 1/2"-1". The beginning of the pipe has just a few centimeters of water, whereas the end has <1 in. of water. Pipe diameter is about 3 in.

<p>My pipes have minimal almost no slope. There is between and inch and half an inch of water in the bottom for the most part. The flow is probably close to a liter a minute though I've never measured it.</p>

Yeah, to my idea , I think depth is not a major concern comparing to the the sludge or suspended solid that enter the pipe. Thus the crucial thing to do is to eliminate the amount of this kind of thing from covering the plant root system. Anyway the flow rate is import. By the way TCLyxn, could tell me the how high the slope of your pipes?

Perhaps that is the best in Hydroponics but Aquaponics and bio-slime will make sticking to that more difficult. I flow way more water through my NFT pipes that that.

Yeah, now everyone I got the ideas saying that flow rate should be between 0.5 to 1 liter / h and the depth the of the water should be 1 millimeter, but I find it hard to keep my system with these suggested rate and depth.

<p>I'm not really trying to be picky but to avoid confusion, a sump tank is generally the lowest point in a system where the pump resides. Also, sump tanks normally have fluctuating water levels. Saying your sump is at the top and filled with sand, well personally, I would call that a bio filter or a sand filter.</p>
<p>Anyway, sounds like you have a pretty good little system going there. Turning over the fish tank volume twice an hour is a good thing. Generally the bare minimum is one time…</p>

<p>Anyway, sounds like you have a pretty good little system going there. Turning over the fish tank volume twice an hour is a good thing. Generally the bare minimum is one time an hour and then one usually needs additional aeration.</p>

I've done a few things to keep the so called "sludge" down.</p>
<p> </p>
<p>First, my sump tank is at the very top of the unit. This allows me to run the system with only one pump, as gravity brings the water all the way back down. Second, the sump needs to be filled with gravel or (preferably) sand. With sand, you can pump the water into the bottom of the sump, under the sand. This will remove airborne sludge and trap it in the sand.</p>
<p> </p>
<p>Also, I have 2 bamboo shrimp that seem to like the brown organics that still collect in my grow tubes. I will often get those particles suspended by adding fresh water directly to the beginning and ends of the grow tubes. The brown organic particles float back to the fish tank and are (mostly) eaten by the shrimp. I have thought of putting a shrimp directly in the grow tube to eat the sludge, but I am afraid he might get caught in the roots and die.</p>
<p> </p>
<p>As far as flow rates go, I have found them to not be critical. Think about it in cycles. How many times do you want the water in your system to cycle in an hour? day? I have a 250gph pump that pumps vertically 6 feet, so in reality it might pump 100 gph or less. My system holds a total of around 50 gallons, so it cycles about 2x an hour. I use PVC pipes in my system and the water level is at the bottom of the last net pot in each tube. </p>
