Let's talk about bio load.

[reefwars]

While they use nutrients they do not really remove them from a system just process them and get rid of what's not used, this may be food for other life including other coral . Certain things can not get processed out and eventually need some sort of export out of the system.

As for the size thing , its not always the biggest animals with largest bioload , snails , urchins and sea hares tend to do a lot of pooping lol

I would bet a sea hares waste is ten times as much as fish three times it's size.

So then, how do I estimate my bioload? Good question, huh??

[reefwars]

I always just get a skimmer twice rated my volume size , seems to work well lol

i have always gauged my bio load on type of fish and how many I have and size and feeding .I have a 90 gal tank and I think I am pushing the heavy side of bioload I don't think theres away to measure other then maybe skimate from your skimmer .I like the idea of a skimmer twice the size or close to more then half of water volume . just my two cents worth

Ya, works well. Guess there's no real answer to this

Way more complicated than I would have ever thought. After doing some reading the bioload also is affected buy amount of available oxygen, surface area (which is probably for oxygen) free swimming area and fish behaviour (sand sifters , schooling)

[reefwars]

Not to mention bacteria of all sorts , these are a bio load often overlooked

I thought you dont care about these sorts of things in the hobby. You are my idol for the LTFA method (and I am not kidding).

lol! You're right, I don't really care, just thought it would be an interesting discussion. I'm looking at all kinds of skimmers that give different ratings based on bioload, and it occurred to me that there really is no measurable way to gauge this. Based on the thousands of responses, it's a tough question, or not many people are as curious as I

For me, get big skimmer, make big foam, remove big poop. Done job.

I read somewhere that skimmers, no matter how efficient will never completely remove all organics, there's a very small difference between the best & mediocre ones in that regard. I doubt that there'a 'formula' to measure bioload that will work consistently for any given person's tank. If a tank is overstocked & under maintained with respect to water changes, I doubt that even the best skimmer will keep up.

One would think that measuring nitrates & phosphates would provide some indication of whether one's bioload is exceeding maintenance or skimming performance. Or if one is battling algae issues. I'm stumped because if anything my bioload has decreased lately, hair algae issues I've had in the past are almost non existent at the moment, but I recently tested my water (after not having done so for many moons) and my nitrate reading was about the highest I can remember.... yet minimum algae issues & the critters including anemone & coral I have are doing well....
