I am making the following significant changes to my setup, primarily to improve how effectively trace elements are consumed by the tank/corals/biofilms. Reduction of return pump flow I have reduced the flow of my return pump by 50% from 2k gph to 1k gph. I wanted to lower it to 5 times my net...

And if Mr Phosphate says its too high, I would really worry :). Re the CO2: Partially agree on the impact of bacteria so that the actual value would need to be discounted to some extent - how long was the shipping time for you @t0mmy108 ? However, 5 mg/l is almost double my nano had after 11...

I am not an ICP expert, but I have recently been spending a disproportionate amount of my hobby time on water chemistry. The report is to be read from top to bottom, meaning the first parameters are generally considered more important than the ones at the end (with exceptions). The ones I...

Not getting the salinity right means nothing else will be either. 35 PSU is the most basic parameter you should be able to manage too. There is no reason to differ from this (significantly).

Resolved now after 10+ attempts, reinstalled the app, tried again several times. Did not work on any of my devices.

Anyone else having issues accessing the mobius app today?

Haha. You are in good company though, since half the US reefers feel this way, I think the reef2reef thread on BOLUS has 66+ tabs by now. Anytime Andy.

Daniel Knop is one of the OGs in the Reef scene in Germany, and has been doing research for the past 30 years on these topics. The Lanthanum method is also in one of his recent books (Trojaner im Meerwasseraquarium, 2020), which specializes in the treatment of various Reef pests. It looks like...

Yes, I am on the brink of taking the chaeto out. Maybe a quick recap of what the refugium is supposed to do: - Improve PH stability due to inverse light cycle. - Reduce nutrients (although I believe this is primarily nitrates) - Potentially outcompetes other algae (?). - Provides a home for...

I would also take the snails if @MichaelB does not take them or not all of them.

The section of the sump where it is is larger, but it never fills it really, maybe one third or so only, so never a lot of cheato growth, since I do manage nutrients. There is probably no point in keeping it except for pod growth etc.

Oh no, the homegrow was used up months ago, probably a reason for my persistent nitrate levels which are now under control, corals loved it though. I use the skimmer for oxygenation and primarily ozone 24/7, so do not like to to turn it off really. I am really not sure how productive the...

For my own record since it is hard to keep track where I am buying some things from these days. CO2 scrubber material of good quality from Ebay.

Yes, but I assumed you wanted to/could put up to two bars on either side, and need the keep the strength of the Reefis - 120s would make them weaker due to the wider spread. But thinking about it, the 60s would then be probably too strong for the narrower area they are covering, so it would not...

The cleaning frequency of the pumps got my attention. But that is probably because nutrients and CA are running pretty high.

Sure, you are welcome to take them. Let me know.

Interesting. I thought with bars left and right and the Reefis in the middle that this would be enough. Probably need to change to the 60 degree reflectors for the Reefis.

ATLAS / Helix combination works very well for all corals except the gonies. Growth is very nice - I am bad at taking pictures, but I will try to show what I mean. I'm not sure I would go with Helix only over the Reefis combination, though. Why change something that is working? Because the...

Agreed, but not enough, unfortunately. I have seen the three gonies I have deteriorating over the past few months while getting 0s every month on the ICP. Some people I find credible stated higher magnesium / close to 1400 mg/l to be a requirement for gonies, combined with sufficient mn. My...

Not rocket science and it has instructions (which is why I would not do vodka dosing). Edit: But not to use when your phosphates are low.
