Lasse, one question. Is your method of dosing daily frozen mysis and artemia good enough to feed the sun coral or do you need additional specific feeding?

Hi Lasse, I missed which conversion factor you use for the photometer results. For the Hanna HI736 (Phosphorus ULR), for example, the calculation is (result x 3.066) / 1000; if I’ve understood correctly, does (result x 3.12) / 1000 apply to Salifert’s reagents?

I use the ULR PO4 method - give me the result directly in PO4 regardless of which reagent I use.

I performed some measurements which showed that the Salifert reagent yielded a value higher than the actual level—a finding that aligned with the results obtained using the Hanna reagent. Based on these experiments, I calculated a conversion factor and applied it to the Salifert results. I have since concluded, however, that the margin of error was too great. The same applies to using the Tropic Marine Pro PO4 kit in the manner demonstrated by the Germans in their video; it did not work for me, likely because the composition of the Tropic Marine reagent has been altered. On the other hand, I was impressed by the test when used as intended—it is easy to read within the 0.03 to 0.1 range, with distinct increments at 0.05 and 0.08 mg/L.

Sincerely Lasse

Yep - it grows rather good at all places it is established. I move on colony to the other side - and it works there as well. No other type of feeds. I stop mos pumps for 10 minutes when I feed

Hi Lasse: I completely agree with you concerning Seriatopora. I have also had different colonies that grew up like weed and then, suddenly and very quickly, they decay and bleach completely. Cutting the diseased parts sometimes work, sometimes doesn't.
Anyway, congratulations for your tank

I succeeded to stop it this time. I cut but I think also the fact that I manually dosed around 20 ml 12% H2O2 for two days and after that restart my Oxidator - first with 6 % and after a week rise to 12%. For the moment most corals is better than ever - especially my Euphyllia of different types

Sincerely Lasse

Good Morning Lasse,
Been a while since I saw you on here..
Glad you are good..

20mL 12% H2O2?!
My BTA shrivels like it's going to die if I dare to add 2mL in my 650L / 171gal system
I assume it was spread throughout the whole day?
