Cross Support Bar:

“The BioSteps outlet fitting is a "push fit compression fitting". Use standard sch 40 rigid 1.5" PVC pipe.
When you first insert the 1.5" pipe it will feel like it is too loose. Push hard and twist and the 1.5" pipe will go into the compression. You do not need any glue. See attachment. Another alternative is to use 2 inch sch 40 pipe. However you will want to purchase a 2 inch rubber coupler with hose clamps from Home Depot. The Rubber coupler will fit over the outside of the BioSteps Outlet fitting. Then the 2 inch pipe can fit inside the rubber coupler.

Waterfall Spillway for Biostep 10

Now you can instantly add a waterfall spillway to your biosteps 10 filter.

It attaches to the existing outlet fitting of your biosteps. This makes it very easy to install the biosteps inside a waterfall because it will attach right to your rubber liner so you can conceal the body of the biosteps. You can also install it as a stand alone unit which pours right back into the pond.

11 inch wide spillway.

The biostep filter just got even better.

Water in Crystal part isshorting out UV. Do I need to replace the whole UV fixture or just the Quartz tube?

Matala Answer:

Water can enter the quartz sleeve in the following ways.

1-Cracked quartz sleeve.

  • oTurn off the pump.
  • oRemove the electrical cap.
  • oDisconnect the lamp.
  • oAt the top of the body near the threads you will see a clear plastic ring which is the top of the quartz sleeve. You will also see small indentations around the perimeter of the quartz sleeve.
  • oInsert a flat head screw driver into these indentations and gently pry each indentation a little at a time as the quartz sleeve will gradually lift out of the bod.
  • oRemove the sleeve by sliding the quartz sleeve up out of the body.
  • oCheck the quartz sleeve for cracks or obvious dmage.

2-Water can enter at the electrical cap.

  • Be sure the o-ring on top of quartz sleeve is in place and the electrical cap is on hand tight.
  • Check flow rate of water pump. Maximum flow through the BioSteps is 900 gals per hour.
  • If flow rate is too fast water can push up around the electrical connection and enter the quartz sleeve.

A little condensation inside the body is common. This would amount to maybe a teaspoonful.
