Is ok to pull your live rock everynow and then and clean it in a bucket of tank water? Ive got some hair algae id like to scrub off. Will have any negative effects on anything?
You’ll want to leave all your rock in your tank.
Constantly taking it out and cleaning them will throw off your tank. I would find the source of the algae and then handle it from there

would also like to hear what damage this would do. Taking you live rock out of the display and scrubbing it in tank water is a great way to get your pest algae problem under control.

Probably depends on how much old crap your gonna disturb from your sand bed. I notice you’ve got a few large softies also, they may be damaged if you’re a bit clumsy. The flow and light on the rocks will change on the rocks, but that effect will be minimal, unless you locate them back in the tank in totally different locations, orientation. Are you talking taking everything out, or just a few hairy rocks? Are your urchins being lazy, and do you have any snails? Happy new year.
do a search of member @brandon429 sand washing and rock scrubbing thread. He's documented actual tanks where the sand has been rinsed and rocks pulled scrubbed and rinsed in fresh rodi water. even surgically scraping rocks and using H2O2 on most difficult algae. Sufficient beneficial bacteria will survive and repopulate to balance very quickly.
after my first 5 years of struggling with algae, cyano and dinos, my rockscape is now set up so I can pull any rock to scrub it as needed and it looks and coral and fish are doing better than any time in my experience. A lot of happiness due to stumbling on Brandon (and others) sharing their first hand experience with sand washing and rock scrubbing.
Tank filled and was almost cloudless :D Turned on the klir roller and added a filter sock and it was clear in 2 hours. Made a makeshift frag rack as I cannot bring all rock back. Scrubbed each frag plug with a stainless steel brush or remounted depending how bad the plug was. Grabbed a couple...

that thread itself is roughly forty pages or so I didn’t count, purely a rock removal and cleaning thread for the unlucky who required that to be algae controlled myself included. My old pico reef years ago was getting perfect input water had perfect params and still needed guiding to become solid coralline, now it needs zero guiding and is on cruise control until it dies from external factors like power outage etc, or an errant nerf ball. Manual control fixed it since I couldn’t stumble upon the lucky balance to cure it. Had tried all manner of clean up crew, perfect ro di make water, your standard efforts didn’t work but hand guiding sure did.
from those pages we can see if guiding is harmful or not, people will post angry updates if that action harmed their reef.
and on page one of that forty pager is sub linked five other threads ranging sixty pages on average, we have two hundred or so readable pages for hand guiding.
don’t permit a tank takeover, period. Don’t let an investment falter just because the lucky arrangement on white rocks couldn’t be found in the first year. If your lawn is prone to weeds and dandelions don’t be the neighbor that sits back and lets it fill up to become the eyesore of the hood, get out there with a butter knife and force compliance until that fescue fills in so thick you don’t have to.
if there was a fix to algae that didn’t require hand guidance three things would happen:
1. Everyone would be using that method and algae challenges would stop permanently.
2. that method would have a readable link we could see
3. and of methods that for sure beat algae and do have links, such as vibrant or fluconazole or grazer threads it’d be working for every single entrant, they don’t. click one, or post it here. They’re full of trade off invasions: I killed my gha but why do I have dinos now or complete cyano takeover?
when perusing algae control posts watch for the pattern: a focus on someone’s tank who won, who found the hands off way and the proof ends there. Any viable method should be featured oppositely: doesn’t focus on the authors tank but instead is made up of solely other people’s fixes, that’s how you know if you’re onto something.
in our hand work study thread above, anyone got a tradeoff invasion or do they post clean hard work tanks

In my experince this is a very useful technique helping reduce algae during the maturing process that usually takes months as the various microbiomes beneficial for corals grow and establish dominace over microbiomes beneficial for algae. As microbiomes fluctuate over months, years and decades it is also a technique I'll periodicly use to some extent on some systems as equilibriums shift. If you aren't aware of ROhwer's book and video you may find them helpful to understand how microbial processes may favor corals or favor algae. Here's links to both and to some other research you may find helpful:
"Coral Reefs in the Microbial Seas" This video compliments Rohwer's book of the same title (Paper back is ~$20, Kindle is ~$10), both deal with the conflicting roles of the different types of DOC in reef ecosystems. While there is overlap bewteen his book and the video both have information not covered by the other and together give a broader view of the complex relationships found in reef ecosystems

I pull out the rocks one or two at a time at least once per year and scrub them down (fowlrs) but did the same with reefs.. I don't even use tank water to be honest. I do also scrub them as necessary in the tank for minor algae cleanup but I avoid allowing it to get out of hand. I agree controlling the source of algae is key. I feed big ol puffers and other meat eaters well. Big and often water changes, vacuuming substrate and keeping filter socks clean makes a huge difference.
So did I understand this correctly in the first video "Coral Reefs in the Microbial” at about 28 minutes the study concluded if we add filter feeders and clams to our reef tanks they will remove pathogens?
I take my rocks in my 40g and 20g out all the time to scrub. When I get overrun with algae or am trying to get under control, it can be necessary. I take it out, pull algae, scrub with toothbrush or metal brush, rinse and put back. I usually do a huge water change too. Sometimes almost 100%. Never had issues except corals open and are much happier withing hours.
Part of our problem at home aquaria is not having the natural predators of algae in our tanks. We cannot as some are just too big. So, we have to balance this another way. We can manually handle it with scrubs, we can use chemicals, we can use scrubbers, etc. It takes time to balance.
Keep an eye on feeding, water source, filtration methods.
Ok thanks for the replies guys! Seems most are in agreement that its ok to pull and scrub rock. I didnt pull every rock when I did it, just like 3 on top that had hair algae on them. I didnt wanna risk pulling it off in the tank, and have it spread around. So I used a little h202 and a toothbrush and bucket of tank water. Just to keep things under control. I dont want the algae to get an upper hand. Alot of my cleanup crew seems a bit lazy, so I wanted to help out.

Short term solution maybe but will it work forever? I guess that depends on you. The solutions to pest algae are herbivores and time... Coral cover is the greatest barrier and so long as there are herbivores and no corallivores it's a matter of entropy. Will you still be pulling rocks out to scrub them frequently in a year? 5? more? I don't think I have the dedication to white rocks that it would take to do that consistently forever. By scrubbing or bathing your rocks in chemicals to kill everything you are just resetting the maturing process. It's a tradeoff I guess.

Yup. You can use Scholar.google to tack down the study. What's can only be inderectly inferred by the stuff presented by Rohwer (his book has almost 100 refferences) is the role of sponges. Here's some more links on DOC and sponges if you're interested into digging into the subjects more.
