Hi all. I have a bit of an algie problem.
Every other day I am cleaning my tank like crazy from gold/brown /green algie. It's everywhere. Any ideas why it's here
My levels are
Temp 25c
Slinity 1.025
No2 0
No3 0
Amm 0
KH 8dkh
Ph 8.4
Po4 0.01

In the picture is the test kits I use and feed for corals and fish and critters

Hi,

You see a lot,  people showing an algae bloom, then showing their nitrate and phosphate readings as zero or next to zero, but unless your lights are on 24 hours or are very very old tubes if T8/T5 then the readings have to be higher than that. Some algae blooms like diatoms can be due to excess silicates, but unless you've just added new sand or done anything strange that's not likely - not that it looks like diatoms in this case.

Have your phosphates checked with another kit, like a Hanna checker or D-D H2Ocean phosphate kit. It's probably down to overfeeding, 3 small chromis and two small clowns don't eat much at all.

What water changes do you do?

I have led lights that come on at 1pm and go off at 11pm
And am only telling you What my test kits tell me. I test my water every 3rd day religiously.
I feed them every evening and only give them what they can eat in about 30 sec.
I will take a sample to my aqua shop to see If my kit is ok.
Someone said I need Phosphate media in my sump?

Every other week I replace 25% of my tank with RO water I make myself.
My TDS meter never shows above 0.04

Hi,

TDS isn't represented in float values, it's represented in integers in hobby available TDS meters. So it's 4ppm then? It's not enough to worry about but the nutrients are coming from somewhere. Maybe overfeeding is making 12.5% per week insufficient.

How's your skimmer running now?

I'm still learning but a few things that helped me were:

Firstly, ensuring scooping up water from deep down to get a good reading...just in my experience anyway surface water gives a less accurate reading.

Try wet skimming for a week or two

Make sure that when you're cleaning the algae off the glass that it's not dispersing back into the water..wipe up and out with a sponge then rinse the sponge in a bucket of water (obviously marine water that you've scooped from your tank). 

Try dropping a feed..they won't starve. How many times a day do you feed? And what do you feed?

Try a sand vacuum to hoover up the algae on the sand every day, that way you're not having to change and replace water every day but you are cleaning away the excess algae that you don't want.
