Backyard Aquaponics
A place to discuss aquaponics

julie, the dying algae will make for a HUGE DO load (bod)

so i'd say clear it up a bit first with the plastic and barley liquid...............

Checked pH this morning at 7:40 am it was 8.8!

Where are you getting cheap sodium biphosphate?
COuld ya just use hydrochloric acid? might be a fair bit cheaper if treating a whole pool.
In my mind the best way this could end, is by the actaul removal of the clumps of algae.
Basically the algae has bioaccumulated so much crap out of the water that it's almost a waste to let it die and rot back into the water. Fish it out and use as mulch

Steve,

I have used a product called COPTROL, a Queensland company supply it. It is a copper based algaecide. Very effective. I have used it with fish (Silver Perch & Marron) in the system as well, but it is critical to follow the manufacturers specs as we all know copper is extremely toxic to fish. Just google the name and you can read up about it. You only need about 5ml per 1000L.

copper is the easy way... but is it safe for eating fish?
I mean I have treated HUGE ponds that had been violated by ducks and had thick pea soup water and big floating algae matts.
Came good in a bout 2 weeks... but be curious about how much entered the fish and stuff.

copper is a big no no for the yabbies etc. read a doc. where even in fish copper toxcicity was quite low.

Don, the algae as i understand it is not clumpy, its just the pea soup style. no ones worried about biofilm on the sides and bottom

Won't it just be filtered out and absorbed over time. Its going to hit the pea soup period anyway...

yeh but i have been through the extended pea soup stage.............there is pea soup and then there is PEA SOUP!

once its hit critical mass (very technical term, i know ) the hot summer just feeds it. i could see differing shades of green swirling when i had problems in mine from "playing"

i'd just prefer julie to start fresh.

besides, the ph swings are chronic.

I can't see how your going to do it without a very large or full water change. You can filter it out, especially once you kill it off cos it will just sink to the bottom. Whatever you put in there to kill will need to be filtered out as well... Your in a very green situation right now.

lol.

i think the barely extract is safe enough. thie thing with algae is that alive it move through filters beause of its small size, dead it clumps. two back washed of the filter should see it right

$12 from the pool shop will do more than the whole pool.
It's not floating crap, but suspended in the water. Doesn't just scoop out onfortunately.

Has anybody thought of using a black max ozone generator to fix this problem i use one in the hydro system and you would not believe how clean it keeps the system.
Jim.

OK then flocculate the stuff into clumps and then net it out.

Yes I just wanna see ya out there with the net sweatin away
Muhahahahahahaha!
I mean if we can't reccomend a massive pain in da butt water change something involving manual labor is the next best option.
Shame I don't have a spare UVC to throw at ya, just gave away a big bad bioforce too lol

how many watts we talkin? 20W wont really cut it will it?
