Environmental Friendly filter with Cartridge/ Algae

[Jam71]

Good morning,

I have had my pool 3 years. I have a 24 foot above ground pool with Hayward Dual speed 1.5 pump and the Hayward Filter with Cartridge. I reach August and my pool is greener than a swamp. Last year, i ended up emptying it in August, My neighbour has same pool but with sand filter and his pool his clear clear. We do the same things same days. Any one else have issues with those filters? I have cleaned the cartridge 3 times since June 1. It is a new cartridge.

Thank you

Welcome to TFP!

How are you chlorinating your pool?

Post a full set of test results from one of the recommended test kits.

Chances are you have allowed the FC to drop below minimum and you now have an algae bloom.

You have a chemistry issue, not a filter issue.

A common misconception is that your filter prevents and kills algae. That is chlorine’s job.
The filter just filters out pollen, dust, dead algae, etc. it doesn’t kill or prevent algae.

No two pools behave the same, not even neighbors. The good news is your pool will tell you everything you need to know, once we teach you to listen to it.

We do the same things same days.

Unless you are coordinating everything to match exactly, then you are not doing the same thing.

If you you were doing the exact same thing, you would get the exact same result.

What exact filter cartridge do you have?

Okay. I follow the guidelines on the instructions. Okay I will do a test and post the information. Last week it rained so I gave .5 more chlorine in my treatment.

Thats still not always the case. One pool gets more shade and the tree in between the two only blesses the one downwind with droppings.

Above ground pools being terrible with circulation when things are working great complicates it further.

Then there's different CYA levels or different starting points for FC when both add a half gallon of chlorine and they might as well be thousands of miles apart.
