Its not excessive par.My Chaeto is dying fast.
II had a FULL chamber of Chaeto two weeks ago, now almost nothing.
I am using a UFO light what is giving 200 par is that too much? Is that melting the Chateo?
Temp is 77
Kent marine Iron - Manganese
Tropic Marin Pro Reef salt
Is the chaeto your only source of nutrient export?Don't want to thread hijack but I am having this exact same issue and my die off look identical and came here to ask same question. Also can't check my iodine level but have brought some `Continuum Reff Basis Cheato Grow`, cant find out if it has any iodine in it but will be dosing as soon as it arrives.
I turned down my Kesil H80 to half intensity just encase that was the issue but from what people are saying here that is not going to be the issue...readings are
Phospate spike seems related as it was stable prior to issues with die off.
Tank is two months old and doing water changes every week.
Most new systems are PO4 limited unless you inherited some old, PO4 loaded rock (which I have no problem with). What is your test kit for PO4?No, Skimmer + socks, think that is too much currently?
I had planned to feed heavy hence the 3 methods but didn't want to over do it until the tank is stable but I'm certainly not going light on feeding currently. I do have diatoms in the sump and so there must be some nutrients?
All my test kits are Salifert. P04 was barely registering (hard to tell between 0 & 0.03) until the last few week or so. Maybe that was the issue then and the die off is generating the PO4 now.Most new systems are PO4 limited unless you inherited some old, PO4 loaded rock (which I have no problem with). What is your test kit for PO4?
Macroalgae dies because something is limiting. NO3, PO4, I, Fe, or lighting. Could also be trace stuff but I've not experienced this problem. A refugium is always a very LATE addition to what I typically build. It is a great tool for solving a nutrient export problem, but IME that doesn't take place very quickly unless someone is feeding far too much.
