Craig1089 Posted December 22, 2014 Share Posted December 22, 2014 I bought a green frogspawn coral around a week ago, when I purchased it, it was dark green in colour, after a free days it's slowly getting lighter and lighter now it's still green but pale green. I thought I could be bleaching it with my led lights, but I have only had them on for 4 hours a day recently to cut down on algae so I'm not sure what's causing it. It seems to open up when they lights go out and as soon as the lights come on shrink? I have 120 litre cube, led lights which are 24 watt which I'm told is correct for the depth of the tank( they are custom made led lights) I have the coral 1/3 of the way up the tank also so it's not to close to the lighting. Really struggling if somebody could help please? Iv tried to upload a pic but it says it's to big Link to comment
GHill762 Posted December 22, 2014 Share Posted December 22, 2014 sounds like bleaching. what kind of lighting was the frogspawn under previously? the switch to led can cause them to bleach a little at first, so if that's the case it's not uncommon at all. what are the parameters of your tank? specific gravity, temperature, nitrate, phosphate, alk, cal, etc. Link to comment
Craig1089 Posted December 22, 2014 Author Share Posted December 22, 2014 They was under LEDs, but suspended from the ceiling so a lot further away from the water, mine are built into my lid of the tank. Ammonia 0, nitrite 0 nitrate 10 can't seem to get that to 0, phosphate not sure, calcium 400ishMag 1300 kh 10 and of 8.2 ph Salinity is 1.024 Temp is 25.5/26.1 Link to comment
markalot Posted December 22, 2014 Share Posted December 22, 2014 Wattage of LED can't be tied to the amount of light it produces. Can you din the LED fixture at all? Does it have different channels? If it does run mostly blue and dim the whites for a while. LED can be deceiving because if it looks bright to our eyes it's usually way too bright for the corals. Link to comment
Craig1089 Posted December 22, 2014 Author Share Posted December 22, 2014 Yes it just runs blue and white, but they arnt dimmable, it's just either on or off. It does look reasonably bright to the eye, but I wouldn't say excessive like mh can look. They way the guy built it was so one end is blue and white the other the same and then just blue in the middle if that makes sense? Link to comment

They way the guy built it was so one end is blue and white the other the same and then just blue in the middle if that makes sense? Kind of makes sense. MH looks bright to the eye because it has a sharp peak in the green, which our eyes are sensitive too. LED does not have a sharp green peak so to look as bright you are bringing along a LOT of extra frequencies. Raise if up higher for now, IMO. I would also look for a dimmable fixture, really no excuse not to have at least 2 channel dimmable. Link to comment
Craig1089 Posted December 22, 2014 Author Share Posted December 22, 2014 Iv added two pictures to try and show you, iv taped off some on the lights on the bottom pic of the tank so it's not got all the LEDs showing Can I buy something to make it dimmable like a plug socket dinner etc?

Tenor Posted December 22, 2014 Share Posted December 22, 2014 Most corals need light for their health (photosynthesis) and light cycle reduced will not helpful. Cut down algae means your tank water parameter is not in correct condition. Turn back the light cycle 8-10 hours, place frogspawn down to sand bed if you think it bleach and do water change 20-30% every 2 week until no hair algae is present. Link to comment
Craig1089 Posted December 22, 2014 Author Share Posted December 22, 2014 Could it be due to lack of light, not be able to photosynthesise the algae that produces the colour pigment Link to comment
cju84 Posted December 22, 2014 Share Posted December 22, 2014 Those pics are too blurry to really tell. Sorry. I'd recommend upgrading to at least the sweet potato model. Link to comment
Maniu Posted December 22, 2014 Share Posted December 22, 2014 I agree with others: Get your nitrate, phosphates in order Try placing Torch in lowest spot of your tank. Perhaps even to far side of the tank where light should be least intense. or raise light if possible. Torches love light however. It is hard to tell what light was used before it end up in your tank. You can increase light intensity every week or two by moving it towards center ot the tank and then upwards. Moderate to strong flow is also recommended. Hope you figure out what works best for your torch. Link to comment
clownfitch Posted December 22, 2014 Share Posted December 22, 2014 All great advice. From what you described the light cycle being cut in half as well as high nutrients are the likely culprit. The green with purple tipped (common) frogspawn thrive under high light when acclimated to it. The less light it receives the lighter the green will be. Mid tank under 160 watt led set at 65% and mine is a very deep green. The small colony at the bottom of my tank is paled in comparison. Link to comment
Craig1089 Posted December 24, 2014 Author Share Posted December 24, 2014 How long does it tank once you up the lighting for them to gain colour back, are week talking weeks or months? Link to comment
Tenor Posted December 24, 2014 Share Posted December 24, 2014 Yes, it could take weeks, months or years to recover. Link to comment
