Aquael Versamax 2 kanister

Skimmer Tunze Doc 9004 , weekly 10% water change with RODI water (TDS-0)

Todays parameters :
- pH 8.3
- kH 10
- NO3 10
- PH4 - 0.33

That - IMHO - is not a cyano 'bloom'.

That is algae growing on bare rock.
I would do nothing

Looks to me the start of the cycle as the tank had no light? The PH4 is a little high and the NO but I would let it take its course ...


I'm no pro though I just read alot ... haha

What should i do next ?

20% water changes on a weekly basis and manual removal with a tooth brush if it bothers you to look at. But I too would wait it out as it will probably self correct.

Do you have a cleanup crew?

You must embrace the ugly phase. You can Vacuum the sand bed and get a power head to spot clean the rock! Keep up with your water changes.

I just want to buy a clean up crew what you suggest for a 40 gallon tank
it is 80 x 40 x 45 cm , 160 litres

One thing is - it seems like you are looking for 1 (or several) magic things that you can do 'now' to 'fix' the 'problem'. Your tank is cycled. You have fish - and some shrimp - and corals - congrats - thats more than a lot of people have.

You also have a lot of surface area - that will grow stuff - and you don't have a lot of organisms that take care of waste. You also have a lot of light shining on the empty space.

IMHO - you can do water changes (probably safer than messing with GFO - to lower PO4) - beyond that I would not do anything. Just realize that water changes alone unless they are large or frequent will not make a huge dent.

Here is a calculator to determine how much a given parameter will change with various water changes:

IMHO - you are going to have various 'algae' covering your rock - until you have other living 'stuff' covering your bare areas. (many people love coralline algae - others consider it a pest, for example). I do not know all of the supplements you are using - I would stop those, feed your fish well and let the corals and shrimp, etc eat from that.
