Can't beat this sand algae

just ran Mg, Ca, Alk and Salinity

Mg: 1100
Ca: 325
Alk: 9.2
Salinity: 1.024

usually my Mg, Ca is higher, so not sure what happened here. Supplemented the tank with 5mls of each.
 
Yeah don't sweat the diatoms. While they are unsightly, they won't harm anything and will eventually clear up on their own as long as you watch what your putting in the tank.

If you want to instantly "clear" them up, get a sand sifting sea star or some nassarius snails to stir up the sand bed. While that won't fix the reason you have them in the first place, it will get rid of the ugly. Or even better, just stir up the very top layer of your sandbed every day till they finally disappear.
 
thanks for all the input guys. i will do an update with the tank...hopefully no other problems arise! learning so much throughout the process.
 
Diatoms are a natural progression in a new tank.

Just watch you intake and make sure your exporting everything your importing. They will eventually clear up on their own since your running GFO already.

He is right. I also suggest to buy a conch snail to sift the sand. It helped my case a lot. I lowered the food and light a lot and it took couple of weeks to get rid of this.

appreciate it frkysl....i have a 2 nassirus snails but i will look into conch snail as well. i think i may have had the lighting all wrong too with my AI prime. i have changed up a few settings.

hopefully the next couple of weeks, i see those phos, nitrates down, the algae gone and coral growth.

I use AI Hydro 52 and i use 29 Gallon tank as well.

Lighting period does helps algae growth but the reason for algae to grow is due to nutrients .. be patient and try to be sure of what goes into your tank...
 
I hanged it at 30" from the bottom of the tank so it's full spectrum royal blue -60 , deep blue 70 , violet -40, UV-40, green -30,red -30 and ram up and ramp down (9:30 to 7:30) but deep blue stays on till midnight for the lunar effect

I am a little higher with the deep blue, blue, purple and UV, 70-80, white at 40 midday. Lunar 10pm-2am

Here is a look at mine

No RODI water? Only RO?

Also Red Sea coral pro salt hurt my system as it raised certain levels way too high. Just keep an eye on your corals with it...

Using RO (no DI) water is absolutely fine. I've never used DI. My guess is that this is one of those normal new tank algae cycles. Keep up the good maintenance and you'll ride it out.

The DI removes metal and other trace elements that the RO cannot. I would never recommend that someone do this. It is better to go to a totally pure water and have the salt put back in known trace elements and such that the aquarium needs.
 
OP uses both, so it's a moot point. Many, many people do just fine without DI, and I have for 10+ years. Sorry to hijack!
 
You need to test the silicates level, because the principal source of food for diatoms are silicates.

What kind of rock do you have? The water change is not the solution, because you need to find the source of nutrients, like over feed, bad rock, any additive...

My live rock is Bali rock that I bought from my local reef shop that is reputable. No extra additives. I use mysis (rinsed in RODI water before put in tank) to feed--once a day, a few pieces for my clown and royal gramma.

If it was a silicate issue he would have blown up with diatoms long before. While that is a food source so is phos and nitrates. This is why it is typical for newer aquariums to go through a diatom period as they have not yet matured bacteria wise to handle nitrates and typically rocks leach some phosphates.

Water changes will remove the nitrates and phosphates from the water colum as will GFO, carbon, skimmer, ect. Removing the DOCs are the main course of action and he is on that at this point... They will go almost as fast as they came as the tank continues to mature.
