Additional LED?

[jason604]

Hey guys I'm planning to get another led fixture to my 75g center braced tank. My LPS has been growing nice and fast but my sps seems to be growing very slow for 7-8 months but color is very nice. I'm currently using the dimmable taotronics fixture exactly the same as this 1

Should I get the same thing or should I try the full spectrum

They are pretty much the same price so which do u guys think will be better? Or is light not the problem and just stick to my one fixture? I do get pretty good light spread "I think" except there's some shade right under the brace and far right and left side of tank. Here's a FTS

You get what you pay for. Personally id get rid of both lights and buy some name brand ones. Thats just my 2 cents

Light it up ! LEDs are pretty direct there spred sucks . My LEDs light up my room. But I still can't grow any sps out of my 25x25 square .

I'm going to buy two hydras for my 48x24x20 tank

I think that light looks fine for growing SPS, I'd look at other things first.

What do u recommend?

I'd go for a bit more flow than those powerheads can do. Make sure temp is about 78/79, stable water parameters, not sure what you have for skimmer, but better skimming typically means better SPS growth.
Keep in mind that parmeters ideal for LPS aren't optimal for SPS.

But based on the brightness of the sand and hotspots on the upper rocks where the SPS are, I'd say you have more than enough light.

Overall though, long term stability is best for SPS

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.

What size total water volume do you have? How much/often do you feed? Any other filter media being used?

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
