Never ending Algae!

Postby Guest » Thu 27 Jul, 2006 09:59

I have a 24' above ground pool w/ a cartridge filter. My pool has not fully turned green, but the Algae appears at the bottom of my pool and in my filter. It has been present for the past 3 weeks and we have shocked (as instructed by the pool company) and have vaccumed & cleaned the filter 2-3 times a day. My pool was completey clear 2 days ago, but my filter was green. Shocked again yesterday and now my pool is cloudy with a tinge of green. What are we missing. If anyone can help it would be greatly appreciated!

Thanks!

We just had a pool built and had the same problem. The pool company came out and dumped two gallons of acid and a bucket of algaecide with dry chlorine in the pool. Within 5 minutes the pool was clear again.
If you try don't get scared as the pool gets worse before better within those 5 minutes.
good luck

First I'm going to state the obvious:
Chlorine is a gas. It has a half life of 30 minutes in sunlight. If you have 3 ppm of chlorine in 1/2 hour you are at 1.5 ppm and so on. It is possible to lose all of your chlorine within a couple hours.
You need to have two ways of distributing chlorine.
1. You need to have sticks in the skimmer or pucks in a chlorinator. If you turn your pump on and off BioGaurd's Smart sticks are awesome and only dissolve with the pump on. They also have borate.
Secondly you need to shock it once a week if not more. You also need to add algicide weekly.
WHen you shock a pool it is a chemical fire. The green algea litteraly burns and turns to a grey ash which is why your pool is cloudy. If it is green and cloudy you need to reshock until it is just grey. Clean your filter with something like Strip Kwik. Run your filter all day until clear.

TO ALL POOL OWNERS WITH ALGEA PROBLEM
I do work at a pool store and we have found the BEST thing you can add to your pool besides chlorine/baquacil/bromine/salt system. It is called ENDURE by Arch chemical. I will make a post about endure later.

Or a bucket filled with water and dissolved cal hypo. Or bleach. This is nonsense.

Read the MSDS, it's 96.5% trichlor. No borax in there.

But do tell us how using trichlor adds a significant amount of stabilizer in the water. How much stabilizer by in trichlor ?

Why do I need to do this if I maintain proper sanitizer levels at all times and have no combined chlorine?

Sodium tetraborate. . .Also known as borax. Available at Walmart.

Hence the expression "You've been pool-stored".

Hi.. I have a 33,000 inground pool which developed an alage problem on Thursday..the water went into green basically overnight. I've changed the chlorine tabs we were using..have tested the water daily at the pool store and they have sold me gobs of algaecide and shock to keep throwing in there.. This morning the pool is still green and I'm sure the water is growing toxic! Does anyone have any suggestions.. I was sold a clarifier but they said do not put this in until the green disappears. HELP

Ask the pool store to measure your stabilizer level. We'll take it from there.

ok ..went back to the pool store.. a new pool store in fact jus to make sure the old one hasn't screwed up!.. checks the stabilizer, chlorine, copper, ph, alkalinity, ..something acid.. cyneratic? every single level is fine.. chlorine is a bit high..but after 4 gallons of shock, 2 containers of algaecide and 2 bottled of granular shock.. not a surprise! I added entire bottle of clarifier mixed with water.. let the filter run for 3 hours..turned it off for 3.. vacumed the pool, backwashed it 3 times today....it made a small difference but 6 hrs later.. pool is still green and cloudy! ..

i actually dove in the pool today to check out the main drain which I cannot see due to density of green and cloudiness.. there were a number of acorns which had fallen in but nothing it hasn't seen before.. picked up the pieces.. just dumped in another gallon of shock and finished off the clarifier..filter is running again..
I asked the pool store guy about putting in something to lower the ph and he did not recommed that? I'm afraid of making it worse.. HELP!! this is driving me crazy ..not to mention I have 120 people coming to my house on Friday for a big family party!

Try to get the actual numbers and let me know what they are. The cyanuric acid level determines what the quantity of chlorine to shock will be. The pH has a big influence on the effectiveness of the chlorine, at a higher pH the chlorine is less effective.

Chlorine, and lots of it, is all you need to clear this up. Post the actual numbers and we'll take it from there.
