do algae release harmfull compounds?

[Tmmste]

I wonder too what extend this is true. I have an diy algea turf scrubber and I do not use other forms of filtration for my sps tank. It has been working incredibly well for the past months. po4 stable around 0.03 no3 around 3. But, I just like to know which compounds are released. It is hard to find any information on this. Julian sprung released a video touching the subject for a moment. What do you know about this Randy?

We are having a detailed discussion in the thread below about Triton's claim that the released chemicals are beneficial. I think there is little data either way about the benefits or detriments to real reef tanks.

IMO, the most likely answer is neither to much extent, except yellowing of the water.

I see, that is quite remarkable.. one manufacturer says it is harmfull.. and the other (Triton) says it is beneficial...

I use to grow Macro Algae more then 10 L.F.S in N.Y.C. together , everything was OK. i end up to dose all kind of stuff to see some Nitrate, was undetectable , PO4 was 0.03 ppm ( NO GFO) , but my SPS ( 99 % ) in 300 Gal. never got good color and grow , i decide to go dif. direction.
According whit Triton i got low Sulfur in my system ( 500 Gal. include 90 Gal. refuge ) so i decide to make my own Sulfur Denitrification Filter, i got zero Chaetto zero Algae Scrubber , my Nitrates go up 50 ppm , i have some large Tangs , my Blue yellow Hipo is about 10" , i got around 20 fiches in 300 Ga. i feed a lot, after 2 weeks my filters (2) start to work , i drop in 2 months from 50 to less then 3 ppm, i just order more Sulfur , i will try to got 0.02 ppm to 0.05 ppm Nitrate , may be to low.....NOT sure....but my SPS looks better then ever , grow is great. For some reason i wont believe the Macro Algae , remove "only" what we inspect.

which manufacturer claims it's harmful, Tim?

Well I asked the creator of the Dutch Synthetic Reefing method if he is going to try algae scrubbers, but one of the reasons he is not interested in (micro)algae is because the released compounds 'may' infuence sps corals negatively.

Glenn has his own, very particular, & successful method for keeping corals. It doesn’t involve algae filtration, & there is no reason why he should use algae. He’s not an expert on algae either.
A response on Turbo’s scrubber forum, to your question there, (I think it you?) puts things in perspective.
As does my response here - https://www.reef2reef.com/threads/a...es-and-metabolites.359116/page-5#post-4471187
And you should listen carefully to what Julian Sprung has to say on the MACNA 2017 video you posted.

People comparing algae filtration on an aquarium, to corals reefs affected by algae allelopathy, is mischevious in my opinion. Mischevious for many reasons. They ignore the fact that algae plays an important roll on healthy coral reefs, while always neglecting to point out critical facts, such as - only certain species of algae are responsible for coral decline; the predominance of the problem is the algae growing directly among coral species, and also coming into physical contact with the coral; and most importantly, it is only when these specific species of algae proliferate to a biomass significantly higher than what typically exists on a healthy reef, due to external forces, that they become a problem.

Just about all corals exude toxins, even acropora. Some quite a lot. Should we stop keeping all corals?

I see, thank you for your reply.
