Diatom problem I believe

[NU-2reef]

If your tank is still cycling then water changes will only prolong the cycle. The diatoms will get worse before it gets better. So just sit back and let the bacteria do it's job. Cleaning the rock will also prolong this because you will likely kill the beneficial bacteria while doing this.

you can turkey baster it off and let it flow our overflow (use a filter sock to catch the bastards.)

my tank is going through its THIRD diatom bloom since starting up 6 months ago. Its inevitable and i have 0 nitrates/phosphates/ammonia, etc. Dont bother with water changes, i find it just feeds them and they grow way faster. Must be trace silicates or something in the water change water.

what i also do is vacuum them out but put the output of the vacuum into my filter sock in my sump so the water is just recycled. then i swap out the filter socks. Unfortunately they are usually back the next day, lol.

Alright... So no water changes for the first month?... Just so u know when I bought my rock I was given 5 corals will they be affected... If they die in my tank it's better than being thrown in the garbarge

The guy was moving to that states and couldn't sell them and couldn't take them

With coral in the tank the first priority is to keep the water quality it up - including water changes. If your ammonia, nitrite and nitrates are good then consider postponing water changes provided the water quality stays good.
