Upgrading tank, keep same algae'd rock?

I'm switching tanks and plan on using live sand (shallow sand bed this time) and mixing fresh water. I currently have a 46 bow and want to go with a 54 corner with sump. I may use my friends 29 gallon temp for my 2 clowns and goby with shrimp. I need to research sump and need to get that figured out unless I buy a used tank.

I have green hair and cyano on my live rocks, should I sell with tank or would I be safe giving a good scrubbing and reusing and maybe cooking a few? I would hate to infect a new tank! Trying to avoid a cycle as I have fish already.

 

If you are using the same sand, it may have the spores for the algae.

 

No def fresh sand

 

if it's not too extreme in terms of the algae, I would think a good scrub (I'd peroxide the algae as well) would be good. If you wanted to "cook" the rock that would mean killing it and then reviving it which would obviously result in a loss of all of the beneficial bacteria.

 

I'd say use some and cook some then add slowly?

 

If the idea is to ditch the species of algae that are currently in your tank, and you want to keep the rock you have, you'll need to sterilize it. The spores are microscopic. Of course, that will mean you start off with dead rock and have to cycle it and repopulate the bacteria.

 

I guess I could pick up some new live and make mine spare base! Had mine for around 10 years soooo lol

 

Plan B: Use the rock, then find and fix your nutrient problem. With or without seed spores, the algae will still come back if nutrients are not kept in check.

 

New live sand, scrub the rocks down real good and like Mr bill said get those nutrients in check. I wouldn't cook 10 years off of any rock.

 

Thank you, sold my tank and got some rocks in a tote with powerhead and heater temporarily. Prob pull next weekend scrub and change water in the tote.
