My skimmer is pulling out about 3/4 of a 2L pop bottle every 10 days or so. Is that good enough? It's a light green

I don't drain mine into anything, I take the cup off and clean it. I'd say yours is a bit too wet, try lowering the level a touch.
What size total water volume do you have? How much/often do you feed? Any other filter media being used?

I've found one important part of sps growth is just to leave them alone. If you are constantly moving them, it will take them that much longer to adjust to it's new placement and it will take that much longer for them to start growing. Many of my corals are in their original placement from over 4 years ago. Some corals took almost a year in the same location to start growing, but once they start, they'll just take off. I grew sps just fine with cheap LEDs.

I'm not able to take out my skimmer cup from my sump without spilling it everywhere due to very tight space. 75gDT with about 10-15g of water in my sump. Feed flake 2x a day and my corals feed reefroid mix with phyto n tank water 2x a week. No other filter media except for a bag of carbon in sump.


U know what. My largest sps the hulk green acro and my monti caps stay stationary pretty much always and are the fastest grower by FAR.

If it were my tank, and some will disagree, I would stop feeding the corals. Feed the fish, add a weekly mysis feeding to the tank, and the corals will manage just fine. Less food going in and more of it getting used instead of turning into high nutrients in the water.

Well I agree with you

I have never "fed" my corals or anemones or clams in my tank. They've been doing just fine with light, flow, and water changes. And I think I have a fairly established reef. Good suggestions there Brad.

What's u guys alk lvl at? Should I look into dosing mag? Never did it( never got the test kit). Is my 7kh too low?

7 is fine. I've never worried about Mg in 12+ years, my SPS do ok :)

Test kit? What's that? My sps do ok too lol.
