Hello All Algaescrubber fans!
This is my first topic on this forum. I'm from Poland. My English isn't perfect, so i'm sorry for any language mistakes. I set algaescrubber 2 months ago. I built it in my new system 150 gallon total volume. It runs skimmerless all the time (2 months from start). I have read the FAQ. I built my scrubber by "one square inch for one gallon water of system volume" and "35 gallon/hour of flow for one inch of length of net". My fish: 3 surgeons (max 3 inch long), 4 chromis viridis, 2 blenna, one six line wrasse, 2 ocellaris.
My scrubber:

lighting: 3 x 24W

Foto period in my scrubber is 18 hours ON/ 6 hours OFF. NO3 was always undetectable, but one week ago it was o.1mg/l (hanna)
There are brown dense algae growing on my algaescrubber. I scrape my scrubber one time a week.
I suppose that, i did something wrong, because it's running for more than 2 months and PO4 is 0,34mg/l (hanna).
Could You check my set up and tell me what is wrong? I'd be very glad.
Kindest Regards
KIDULT

Nice construction. Your biggest problem is very high phosphate, which is causing black/thick algae. Black algae must be cleaned as soon as it grows, because it will not grow any more. So clean every 3 days until the growth starts turning green.

Also, more even flow would help. A slot (with screen inserted) is best for even flow, but since you already have yours built, drill twice as many holes in the pipe. This will even out the flow.

But most important is cleaning more often. See here:

6400k light? Should be lower like 2700K.

How often have to be hairy green algae be scraped?

Every 7 days, in your sink.

Damn! KIDULT; I just realized your stand is painted lavender!! I love it!
I painted mine International Orange but after seeing yours I wish I'd painted it your color. 8-)

Don't change the color. Air/Sea Rescue Orange *is* the preferred color for marine equipment. For safety.

thanks, i like this this color too.

Could You write, how many time it will take to go PO4 down from 0.36 to 0 ? One scraping for 3 days.

Too early to tell. If you cut your feeding in half, it will be quicker. When you screen starts growing green, it is working.

hello,
After last advice (1 scrape for 3 days) my tank achieved PO4 0.07 (hanna) from 0.36 - 4 weeks ago.

Po4 - 0.02 (hanna)
No3 - 0 (salifert)

Thank You All!

I'm continually impressed at what these can do. I've been purposely overfeeding quite a bit to see how far I can push it, and phosphate has yet to get above .01 ppm (used to be .03). Nitrate never registered to start with and still doesn't.

Anyway, I'm glad to see you've gotten your phosphate under control. Congrats!

how about trace elements? they are probably consumed by algae much more than in skimmed tank. is it correct? how about iodan, iodate?

Algae can be a significant sink for metals, etc. Many, especially red and brown algae, uptake quite a bit of iodide/iodate. I don't recommend adding it back, because you can't keep track of any influx via other sources, of which food is often a significant contributor.

And just think how much iron is in nori too. Remember that algae is 90% of the life in the ocean (except bacteria), so if algae gives or takes something, then you can bet that it's the way it should be to operate correctly. I don't dose anything really.

best po4 result - 0.02
next week - 2.5mg (end of scale in hanna) - i suppose that's because bad DI, i change it for new and fresh one.
i had bought ECOPHOS One liter and set it.
next week - 0.09 mg/l
and next week later (today) - 1.09

what is going on?

Something not scrubber related. Time to go reading the other forums for a checklist of things.

I reckon its RO-DI related. Or food.

mysle ze to jest cos zwjazane z filtrem wody. Albo jedzenie.
