Yet the skimmer was the major workhorse of your setup. I'm not saying adding macro algae won't help but you have to be realistic about it. Adding a handfull of chaeto to a 50g tank isn't going to do much. Couple that with a skimmer which is going to pull the majority of junk out of the water and then sure, it is a good combination but a tiny refuge on a big tank alone isn't going to achieve miraculous results.

The fun thing is that it's simple to prove me wrong. Take your algae and put it in a bucket of water for a week with that clip on light over it. Test your nitrates to see how much they rise and voila, you know how much work the macro algae is doing.

It wasn't about how much macro i was putting in, it was about how much I was pulling out. And I pulled a lot out. All that chaeto grew from nutrients that passed the skimmer and made it to the chamber. It was a poop load of solid nutrients in the form of algae. I can argue with that.

how much is "alot"? Also, what kind of macro is it? For example, I'm pulling enough of either chaeto or grape caulerpa out of my tank every month to halfway fill up a 5g bucket. That's either approx 1lb of chaeto or 2lbs of caulerpa.

One of the reasons for fast growth is the amount of nutrients in the water. Less nutrient and nitrates will slow the macro algae growth.

Yeah, but different types of macro algae have different limiting factors. Grape caulerpa for example is an amazing macro algae that requires a lot of phosphates. In a tank with fairly high phosphate it will rapidly consume nitrates out competing chaeto. However if you drastically reduce the phosphates in the tank then the chaeto takes over and out competes the caulerpa. Macros need to be selected based on the goal of the tank.

ANYWAYS..

To the OP..

i have a 46g bow front i just shifted to with all my old tank stuff and all i have is a topfin-75 filter that i deep clean once a months and swap polyfill weekly and carbon cartridges bi-weekly, it keeps my water crystal clear and parameters very stable. nitrates never get about 10ppm in my tank with bi-weekly water changes opposite of the cartridge changes, i see no need for a skimmer i have 60lbs of live reef grade sand, and about 45lbs of live rock soon to be about 60lbs in a 2wks time adding in rock slowly to keep everything stable with minimal die off, i really dont need a skimmer as of now, but ill be adding one later when i get more fish, i have a flame angel, 2 caramel clowns, six-line wrasse, soon to be orchid dotty back, 2 purple firefish and a tiny-small yellow tang (1.25") so ill be using a hydor slim skim rated for 65g after all that, but for now, skimmer-less is fine
