Hi Tristren
You have two fishes that can eat your algae if the get a little bit hungry. I can say that you feed your fishes a little bit more than I feed my 30 + fishes. I only use frozen food and maybe 2 cubes a day - sometimes more and sometime less. I should also look for an urchin or two. The long spin blacks are very good in eating unwanted algae and they are like a ballet dancer between the rocks. They do not push them away – just dancing over rocks and corals.
Like you I use tap water – the quality here in Gothenburg is very good and the only thing I concerned about is copper from the copper pipes that’s is in common use in Sweden. However – it seems not to be a problem in my house and because of all algae you have - I do not think its a problem for you either :).
I think that the best strategy is to ad some more algae eating animals, starve a bit the one you already have, clean you fuge from GHA rather often – take up the Chaeto ball and clean it from unwanted algae and spread it out over the bottom of the fuge. I have hermits and snails in my fuge too.
I will not give the advice to try to lower your PO4 and NO3 levels – you will get a plenty of that type of advises but when a GHA problem already exists – my believe is that its total uninteresting what the levels are – the algae will grow anyway. The only way to get rid of them is to maintain a stable clean up crew and as much as possible manual removing. And what are your NO3 and PO4 levels anyhow because the algae in your fuge does not look like what I’m calling a GHA. I should not be surprised if your NO3 levels actually is low.
Edit Najer was faster with the fishes :)

Ok, I am consistently impressed with both your system and that of
@najer as well... so I will work to reducing the amount of food. Though I do want to keep some diversity in the food and keep it spread out over the day which makes it a bit harder. I do want to have a system that I can feed a lot, but I know that will take time. And I also don't want to make a system that is "polluted" by too much food.
A related issue (I suspect) is that the water in the main tank is a bit hazy. After reducing feeding, a bit, would you recommend a skimmer or an oxydator as the next step?
You both have very full and healthy looking tanks... Is there anything else that you "feed" aside from the frozen fish food? Anything for the corals or phytoplankton?
I am planning on getting a long spined urchin, so maybe sooner rather than later. Hopefully one that comes with a zebra crab like yours Lasse!
On the water, yes I am not really worried about the quality of our tap water (the discussions of many posters about their water makes me a bit concerned about it when I travel to the US though...). But I was finding that there was an ammonia smell in the water tub. I figured it was from the prime. So I decided to move to ro/di to be safe.
That was more for the snails than the GHA though. I don't like how many of them are dying. I'm pretty sure they aren't starving...
I'll do that with the chaeto, thanks for that tip. There are a couple of crabs in there now and I'm planning on moving down some of the snails that are looking a bit sedentary up in the main tank. Thinking it might be a bit easier for them in there, and easier to pull out if they do die.
What do the two of you have in terms of clean up crews and what mortality rate do you see in your snails?
Thanks again to you both for taking the time to help, Tony
