Hi everyone, I’ve been looking to set up a macro algae tank. Very intriguing to me. I’ve done some reading in the past few days and lots of information to read.

I was wondering if anyone has any experience with this kind of tank and if there are any tips for someone trying to set up a macro algae tank.

Thanks!

I have a macro and softy tank. in my limited experience....I say wait for your tank to cycle before adding macro. I added macro right after the tank were up and most just melted away. I suspect lack of proper nutrient was the cause.

I ran a macro algae tank for 5 years. Great tank. Super fun.

Here is what I learned. It is almost impossible to get enough water movement once the thing takes off. My tank below turned over 135 times. You wouldn't know it by watching it. I ended up putting spray bars under and through the rocks to stop detritus from building up, that really worked.

They need a ton of food, and also good filtration. I was carbon dosing. Seems weird to say both, but macro needs available nutrients to grow, but also bad algae grows faster. Having a limiting nutrient, it was phosphate for me was helpful for a balance.

Many macros grow slow, some grow fast. Keep one fast grower as kind of a safe guard, so your others can grow. I used fern as my fast grower and would pruin it a few times a week.

Pick your snails and hermits carefully so they won't eat your display pieces.

Some species do need good stable alk like halmedia.

Go for a balance of color and textures. All greens blend in, you have to mix them up a bit for them to pop.

Macro's pair well with LPS because you can drop 5 cubes a day in a 40g and be fine.

Pledosophy, that was beautiful tank! Besides the nutrients, what kind of parameters did you keep in terms of temp, salinity, and pH?

I would want to try a harem of clowns in a macro algae tank. Not sure if that would be a great idea, a lot of my research didnt show much in terms of having huge livestock.

Ya know... I didn't keep anything else in check at all really. I dosed calcium occasionally, but that tank was from 06, and I didn't know enough on dosing to have a regiment like I do now, and I only did one water change on that system in 5 years, and that is when I moved it.

I think a harem of clowns would be awesome. You could put in a few anemones in there with them and really feed those guys a lot. There are some great low light nems outside of the RBTA norms that would do well with lower lighting, if you wanted to save money on the lights. I lit my tank with a 150w HQI bulb (metal halide) but most of the algae's don't need much light. I'm not sure what size you are looking at doing to suggest a type of light.

The only real problem I forsee with the clowns, as a clown lover and someone who has had a clownfish in his home for 15 years+ now, is when you go to pruin the tank you better wear some thick gloves, or put the clowns in a net. I had to pruin my faster growing macro's weekly at some points and well when my clowns got bigger in my reef is when I went to the no hands in the tank methods. Those bites can hurt :D

Glad to know I’m not a bitch ahaha. I thought I just had baby skin, those little bastards used to draw blood everytime I reached my hand in to grab a frag or place something in a different spot

Params should be very similar to your reef tank with the exception of running higher nutrients. In my 10gal AIO I do about 2-3gallon water changes and dose 1/4 of the recommended of ChaetoGro weekly. This helps with traces that the macros consume and keeps the red nice and vibrant in your “red” macros. I do feed very heavy with the three fishes and tons of different inverts in the tank.

All of the my macros/gorgonians come from other hobbyist/reefers usually through trades. Just send me a message when you're ready for some macros.

That tank looks awesome @weelo111. How do you get a wide variety of macro algae? I was looking through reef cleaners website and they don’t ship many of their macro algae to California
