Agree this is the best advise...no need to chase numbers right now take it easy. It will get thereI use this too.
However, at 6 weeks you shouldn't really be dosing anything. Your biome will be changing so much every month for the next 12 - 18 months. Your bacterial colony balances will be bouncing all over the place.
Just maintain temp, salinity. Change 20% water every 2 weeks. Let nature do its thing.



Hi and thanks For getting backI've set up a dozen tanks the past five years....some with LR and some from dry. Very rarely have I seen nitrate creep up until the tank is at least a couple months old and I rarely do water changes. I think the OP is parameter chasing on too young a tank.
I also don't get the phosphate issues. I strongly suggest testing fresh mixed salt water you are using to see if its your source water. I feed the heck out of my tanks and if I turn my skimmer off I can quickly send nitrate to the moon even with a light bioload. I cant ping a phosphate test without adding plant fertilizer and it doesn't stay long.
Agreed. That’s what I would do.Just start using something like rowaphos (GFO) in a reactor which will remove phosphate from the system. You will need to change it regularly to start as it becomes spent otherwise it won’t work.
Its also not very effective in socks, it really needs to tumble in a reactor
I use it 24/7 in both my tanks, and ‘heavy’ to keep phosphate locked down at less than around 0.03

Thanks Spacey, will have a look at nopox. I thought Vibrant was a rip off (overpriced) until I found out it was hand made in zero gravity on the international space station, by the Queen of England![]()
It was proven that all the quality frozen foods had less phosphate in them than your fish need to live and grow.
as Lanthanum will remove the oxygen from the water and fish don't like it.
Will do a 20% water change tomorrow
