You have $ on the line with big tank cleanings, best to read it all it’s only about fifteen mins.
That’s the job
consider the angles before we do anything to see how true surgery works.
Just pondering and prep so far, and a little test. No big work yet so we consider and plan safe, no loss surgery
That thread is meant for full system cleaning.
Without cleaning the tank yet, you can lift out any portion of rock that is easy to get to and won’t topple the rest over and make a cloud in the display so we can do a test
Lift out that rock and set it on the counter. If there’s a coral attached, nbd mine stay in the air. Yours can have saltwater dribbled across it, be creative they’re tough.
Use a steak knife to tip precisely and drag, scrape, debride like wound cleaning all the crud off /half/ a test rock and leave the other half invaded and don’t touch the sand yet. We are removing only one rock carefully and seeing how it responds to a target cleaning before we run the whole tank
We test to see how the growths respond, how the cleaned area looks after a few days. No harm to your tank since we do not stir things up we are spot testing using external work outside the tank
Once the knifing and scraping has dislodged/cleared truly half a rock + bunch of saltwater only rinsing so that the worked section is clear, like sea bass above, that clear, then just open a bottle of peroxide and pour across the clean section only avoiding the coral if any. Don’t pour on the bad section of the rocks this is a knifing and rasping and peroxide at the end for a perfectly fixed single area
Rinse the rock off well with saltwater as you work it so it doesn’t bring cloud into the tank when you put it back to be charted among the non worked areas
If you like how it looks in a week, then we do the rip clean where even the entire sandbed is taken apart and rinsed fully and all the rocks get the job all at once.
If you decide in a week it doesn’t look awesome we’ve hurt nothing and risked nothing having learned at least for sure what half a test rock does. As of now, any guess is valid. After a test rock, you actually know something specific about your invader, how it rebounds, if it stays dead etc
It will take time and precision work to rasp with a knife half a cleaned rock as clean as sea bass above but that’s the deal with waiting, still needs done. The peroxide doesn’t go on the target, it goes on the fully cleaned area only, let sit two minutes, rinse that scrape area and put rock back.
We don’t need to know the type of invader you have or your water params which is interesting, this method works on all invaders.
Reef flux is best applied to the clean condition tank, as growback prevention
that was about 5 days ago so we will see what it is tomorrow
