Welcome! We have LOTS of information on lots of topics, and people like Ted who have specific knowledge of pump and filter equipment.

While this is your immediate problem, you should learn about pool maintenance. Adding chlorine was good. Adding clarifier was probably a waste of money. But the guys in the pool store won't tell you that!

Watch out for them talking to you about "Total Dissolved Solids", "Phosphates", and "indexes". You've heard the expression "If you can't convince them with facts, then baffle them with BS".

Really, you should be concerned with chlorine levels, pH, Total Alkalinity, Calcium Hardness, and CYA (Stabilizer) levels.

We always recommend a good test kit. And we suggest that you get what's called an FAS-DPD test kit. The gold standard is the Taylor K-2006 and K-2006C (the latter just has bigger bottles of the chemicals you use). This can be had directly from TaylorTechnology.com or amatoind.com.

A perfectly good substitute is from Leslie's Online web site: lesliespool.com and is called the Chlorine FAS-DPD Service Test Kit--a clone of the K-2006 in a Leslie's box--even uses the same Taylor chemicals!

Be aware: a DPD service test kit is not the same an FAS-DPD service test kit. DPD is one kind of chlorine test, FAS-DPD is another, and much better one.

The price ranges from about $50 to $70 and will be the best pool investment you ever make. It will become your touchstone, your security blanket and your safety belt and will tell you AND us almost everything one needs to know about your pool!

All the best!
