Swimming Pool Algae With Baquacil Use

by Linda Finnerty
(Houston, TX)

Cannot get rid of pool algae using Baquacil products. I have used the flock once and no luck. Water testing said sanitizer is high but flock should work after once or twice.


Any ideas short of draining the pool and switching to chlorine-based products?




Thanks for the question Linda

Unfortunately you're not going to find too many people on pool forums, this one included, that are fans of Baquacil products.

I don't have anything personal against the company or products, it's just that I've personally found the using Baquacil will eventually cost you more in the long run.

Their sales pitch is alot of the "no more chlorine smell".

This is true, but with the added expense of the products and the never ending use of it, not to mention you'll spend too much time fighting your pool than swimming, it's better to switch to a chlorine based pool.

Flocculation (or coagulation) is adding chemicals to the pool that bind tiny particles together into larger clumps. These clumps settle to the bottom where they can be filtered and/or vacuumed away.

Baquacil products might be good for the start of the season, maybe 1/2 way into it, but I know from personal experience, and from many of my customers, that it's just not worth it.

Not knowing how much you have in your pool, you may need to drain 1/3 - 1/2 of the pool water, refill, and start again.

It is unfortunate, but it will take some time and filtration to get the Baquacil out of the pool. To get rid of your algae you can go here:

How Do I Clear Up My Well Water In My Pool..It's Green

by Candy
(Monterey, Indiana)

First I started filling the pool and the water had a little yellow color.

Then we went to the pool store which told us to use Metal Magic algaecide and shock.

First we put Metal Magic in.

We ran pump for 48 hrs and then we added the algaecide. Ran pump 12 hrs then we added the shock.

The pool still hasnt changed.... what can we do?




Answer:

Thanks for the question Candy

We first need to understand what each product does.

A metal sequestrant does not remove metal from pool water. It holds it in solution until it can get filtered. Then you backwash the metal out.

Because metal sequestrants break down over time and get filtered and backwashed out, you need to weekly dose your pool if you have high iron and copper.

Metal sequestrants that are based on HEDP, phosphonic acid or something similar are the most effective.

Jack's Magic Blue, Purple, and Pink Pink Stuff, Metal Magic, Metal Free, & Metal Klear are very good.

Be sure any algaecides you use don't have any metals or copper in them. You don't want to add to the problem.

An algaecide does not remove green pool water or kill algae. It is used for preventative measures only, normally on a weekly basis.

You can use a PolyQuat 60 algaecide when shocking a pool as added insurance against an algae bloom because the algae will be consumed by the chlorine.

Your chlorine level will drop very quickly, so using an algaecide during the shock time is good.

Shocking a pool, then a daily manual dose of chlorine to keep the chlorine level up while the algae is being killed is the only way to get rid of an algae bloom and green pool water.

Daily brushing and backwashing is also recommended.

It's best to put in the metal sequestrant and allow for a complete turnover of the water. At this time you'll want to backwash.

You did run the filter for 48 hours, which is what you want to do. Keep filtering and backwashing.

A 2nd dose of sequestrant might do you well. Allow for another turnover of the water. This is normally around 8 - 10 hours.

Then do your shock. Here are links and charts to help you out:

Pool Chlorine


Because of the constant backwashing, your water level will drop. Be sure to keep your pool topped off.

1/3 - 1/2 up from the bottom of the skimmer.

Keep an eye on your stabilizer (cyanuric acid/CYA) because if you're putting in fresh water, you'll be diluting any CYA that's already in the pool.

This should be kept between 30 - 50ppm.

It's this time that you'll need patience. There's really no "quick fix" when dealing with pools. It does take time and effort.

Keep filtering and backwashing.

Try to add chemicals in the evening and retest in the morning.

GPH Too Low & My Well Water Is Yellow

If the water is not being moved @ say 1500 gph, can that be part of the problem?

And can I put an algaecide in it with the salt pump on?

I also have well water. Our water is yellow anyway.I've been fighting this for @ least a month now and it s getting expensive.

Please help.

(DROWNING HELP)




Thanks for the question Stacey

A normal pool pump motor should move your water between 40 - 60 GPM. That equals 2400 - 3600 GPH. I'm not sure what is meant by "part of the problem".

The questions says that the well water is already yellow and you're trying to get rid of that. I'm wondering if that's what you mean.

The water is yellow and you've tried to correct that, but with the water flow so low it's not working?

If that's what I'm reading, it could be part of the problem. There could be a few reasons why the water flow is so low.

Wrong sized motor

Bad impeller

Clogged filter

Clogged lines somewhere

Many times well water has lots of impurities, namely copper and iron. You can use a good metal sequestrant to try to get rid of the heavy metals already in your well water.

You can have your iron level tested at a local pool store. More than likely the iron is low if you never had an issue with staining.

Metal sequestrants that are based on HEDP, phosphonic acid and/or its derivatives are the most effective.

Some popular brands are Jack's Magic Blue, Purple, and Pink Pink Stuff, Metal Magic, Metal Free, & Metal Klear.

Be sure any algaecides you use don't have any metals or copper in them.
