bleach is fine. I would think you are ok after one bleaching overnight. Rinse tem well and let them air dry. Smell them to see if you think you need to rinse and air dry again.

Yes I will be pumping a small portion of the water return at the top that's why I don't want the hole to be that big. But if it's too small it might not break the suction. I am OK with a few return at the top. In fact I have 5 returns 4 at the bottom and 1 for the top return. most of the overflow intake is at the bottom so having some returns at the top will help circulate the water and bring down the dirt rather than just return at the botton and input or overflow also at the bottom. But I don't have control over this hole compared to all my other returns,which are all valve controlled, once its drilled it will be like that so I just want it to be minimal just enough to do its function. Check valves are ok but I dont really want to spend that much on them if there will be a cheaper alternative. And they're a bit expensive too. The size of my returns are 1.5" and the water drop is about 5' so suction is going to be strong. I drilled a 3/8" D hole on the top return. Is that going to be enough?Danh;1184571; said:
Thanks I'll try to clean again the weeds(hope they're dead and easy to take out now). Its still cold up here to go out If it gets warmer in the afternoon Ill clean themDanh;1184576; said:
I've been reading a few threads here on bulk heads, and it seems that every body is using them. I did look at the price when I was putting my overflow holes and i guess the price made me back out. I have 4 - 3" and 7 - 2" overflows. If I did that with bulk heads I would have spend hundreds!! With the couplings I only spent less than $30 and I can't really see the advantage of using bulk heads, not enough to justify that much of a difference. I'll just hope that my cheap couplings will do the trick. I did have to modify my overflow, so the modification holes were done on a really tight spot, hoping I sealed it well. If I am ever going to lik on my coupling it will be on this modification holes.
I measured my internal tank size and with all the BG and sunk in window I am only about 550 G. I was originally planning to use 2 - 3,600GPH pump but. thinking about it... What is the point of having efficient filter and having less Water Change if your electric bill is going to kill you? My plan now is just to use 1 - 3600 pump at 6' will be about 2.5K GPH which is still more than the minimum 4X turn. I'll just use the other pump when flushing or something, but it will still be hooked up to the returns, just not used all the time.
If I do lesser GPH Ill have to higher my over flow or make it smaller to have the same water level and that is where the wide opening comes in. All i have to do is plug in that couplings with a half open stopper.

.25" 90* apart just below the lowest usable water level (considering what the sump will hold also)

Bleach is fine, you can use a little dish soap to help break down the bleach if they still smell, just rise very well again.arl;1184563; said:
Put them in a clean bucket, fill with water wait 2 hrs and do a chlorine test (test water before for a baseline) if your still concerned.

Cool!! I am OK with as much as 3/8". But it is only 1 hole per pipe return (hope you didn't mean I'll have to put several holes). The hole will be above water level at all time. Only draw back is it will create splashes. I might make water slides or something to eliminate it, but its not really abig deal. My sump is almost as big as the tank so I am ok for maybe as much as 1 minute delay/back flow before total cut off.Dr Joe;1188338; said:
Thanks for the tip on my bleached Rocks !!
