The goal is really to standardize things so we understand the methods to grow macro algae, what induces their growth, what induces their new growth,. gamete formation etc.
Then when coral folks get a pest algae, which is simply a plant/algae that is where to do not want it, they can have decent cause and control methods to address it.
Now if you want a macro algae somewhere, we also have the ability to grow it and cultivate it.
In this case, it's not a weed.
The reef folks have valid points when they do not want a seaweed to take over their precious coral. Most cases, the larger tanks have no issue growing Calupera without dosing, they are dosing, they seldom do not measure nor relate the uptake of Macro algae to the tank's inputs.
It's a fairly simple two biox model, what goes in, must come out or else it stays in the tank.
You can export with macro algae, with skimmers, with water changes, with coral and fish growth, mechanical/chemical filteration etc
But given a choice between these, Macro algae and marine plants sure look nicer and can be sold etc. See how much $ you can get for some skimmate
Other folks will not see the beauty of using plants to provide a nice scape and the export of nutrients. Many Fish only folks do not like plants for their own reasons, but oddly, they do not use plants as filters either.
I find that distinction between Marine and FW use of plants very odd.
The fW folks need to use the plants more as filters, and the marine folks need to add the macros to their scapes and various layouts.
It's not about replacing coral reef tanks, it's about using the macros optimally to filter the reef tanks, and also to have a nice looking marine planted tank, something that's not always the goal of most reef only folks!
So you have a different goal than they do also.
If the goal is to use a refuge optimally, then they should listen.
But if they think they have a perfect system and have all the export they need, have no more room for improvement for their system, then suggesting anything to them will not do any good.
If they have that attitude, do not bother.
Just punch holes in their logic and lack of interest, yet obvious passion to debate rather than test and see if there is something they might yet learn about.
I freely will offer advice, designs, hypothesis, ideas, background references to consider, and observations to show anyone that's interested a method/s to look at things and learn more.
If they are truly interested in learning, they should consider testing and discussing things more in depth.
If you want to translate the Marine macro algae articles I have, into Swedish, let me know. That will help.
Realize the coral grower's goals might be different than yours, so they will likely only use marine macros as filters, but the Halophila grasses etc, can easily be added to reef tanks.
But we can heklp optimize their coral growth as well as bacteria with macro algae vs a skimmer.
Bacteria can be limited by low organic carbon levels, often from too lean reef tanks. This slows the denitifyers way down. DBS's and refuges go well together for this reason.
It's very obvious things like this that often are not even considered in the reef hobby.
Not sure why, too much critter focus, less cycling and optimizing focus near as I can tell.
BTW, here's a reef I maintain for a client:
