I have been struggling with getting my fish tank clear. One dose of this clearly fish in just hours.

Works very well. cleared pond in a few days, can now see right to the bottom.

Something went wrong cannt see the bottom at all help

I bought this to clear the water in my 40 Gallon goldfish tank. It worked only partially and so I plan o exchange water and start with a cleaner tank to start fresh.

Item recommended by store staff. Actually does keep my pond clear.

Products themselves are solid and well made. The posted required hole diameter on the product page is mistaken when it says you need a 1.125" hole for the 1/2" Diameter Bulkhead. I bought (3) 1/2" and they were all Thread OD of 1.14". Now I understand that when you cut a hole you often end up with slightly oversized or undersized holes depending upon quality of the bit. On my Acrylic Aquarium they were dead on 1.125". That being said I simply broke out some 100 grit sandpaper wrapped around a jumbo marker and opened up the hole. Should you be dealing with a Glass hole you may not be so lucky. So not sure if the MFG over sized the OD of the threads or the hole size was misprinted. I think the threads are correct and the chart is off. The 1" Bulkhead has a thread OD of 1.680" so the chart listed hole req of 1.75" is OK. I didn't buy any other sizes but keep it in mind. If your stuck with glass you may be able to sand the threads OD to reach a tighter hole, insert bulkhead, wrap exposed threads in pipe tape and then tighten the nut.

Not using for a aquarium so thread length was short but the table I'm using is hollowed core. Sorry not much to say about the bulkhead it's a good solid product
