Balancing Parameters

[paulgriffin971]

So long time reader, short time poster. Usually search, post, read to find my answer and move on like everyone else. Red Sea 625xxl running for 4 months now. Aqua max C3 skimmer. Gyre wave maker, and jaebo 10k. No UV, no reactors, etc. want to just run a softy tank. Maxspect razor x 300watt at 60% blues, 25% red/whites 9am to 7pm with one hr ramp at start/stop.
Here’s my questions:

1) what is the easiest way to maintain proper PH? My PH fluctuates from 8.1 at noon, to 7.5 at 10pm. Right now, I’m dosing Seachem fusion 1&2, but PH still fluctuates beyond what I would think is high/low in a given day.

2) How do I lower NitRITES? I’ve added about five bottles of turbo start over the course of 3 months, and still my nitrites are running in the 1 to 2ppm range. NitrATES are 10ppm, and ammonia is around 0. Seems my cycle is getting stuck. Fish and inverts seem perfectly happy.

thanks for the help

Welcome!

I'd ignore nitrite. It is no concern in a reef aquarium (unlike fresh water).

The Reef Fusion is not a way to control pH. Are you monitoring alkalinity?

How are you measuring pH?

 

[paulgriffin971]

Monitor ph with both an apex probe(calibrated) and Hannah checker. Yes, I monitor alkalinity is right at 8.5- 9 and stays stable.

The pH 7.5, if real, is a concern (IMO), and I'd look to raise it.

This describes some options:

You are cycled, it isn’t stuck.

10ppm nitrates is very reasonable.

I would stop adding bacteria as you are cycled.

Make sure you have ripples on the water surface, this helps ph and also make sure the room is getting fresh air, these 2 things don’t sound like much but can make a real difference.
