I've only had it for about a month. Params
Tank: 75g, 12g sump, 10g refugium
pH: 8.2-8.3
dKH: 10/11
SG: 1.027 (usually at 26 but had some ATO issues)
Ammonia: 0
Nitries: 0
Nitrates: 0 (trying to raise them)
I haven't changed my water in 3 weeks because I'm trying to raise my nitrates. I do not dose anything BUT two days ago I mixed up some kalkwasser using pickling lime and injected about 1ml into different majano anemones. I did the same this morning (before I noticed the tube anemone).
Also, 2 days ago, I upped my dose of GFO from 1 tbs (yes, 1 tablespoon) to 2 tbs and I also added activated carbon. Mixed both in a reactor.
Filtration is a 12g sump with an algae turf scrubber, filter sock (4"x8"), and poly filter. I replace the filter sock every 4 days or so once it starts to overflow. I haven't replaced the poly filter for a month or so. It's just pillow stuffing from Michael's craft store. I have chaeto and feather caulerpa in the sump. I have feather and halymenia macro in the refugium, along with unwanted red hair algae (only in the refugium, for now...)
I had 5 mangroves stuffed into the overflow box hanging on the back of my tank but I took them out last week to try and raise my nitrates.
Lighting is 2 DSunY (chinese brand) panels, with total LED power of 162W (27 LEDs per panel). They ramp up to 100% around 11 to 2:30PM then back down. I recently (3 days ago) changed the night settings to mimic the lunar cycle.
Care of anemone: I usually feed it either chopped fish or chopped squid (grocery store stuff) once or twice a week. It probably also gets some of my homemade fish food (salmon, nori, shrimp, scallop, coral frenzy, hommade garlic extract, don't remember all the ingredients) once in a while.
Related note: I also have 2 GBTA, one of which is the split of the larger one. That split happened about 8 months ago, when the tank was about 5 or 6 months old. The tank is 14 months old now. I do recall that at the time of the GBTA split, I added a condy (RIP) a day or two before. This time, maybe the split is caused by either the additional GFO or the kalk?
I'll post anything else I think of
