February 9, 200719 yr comment_146723 Hi All, I've come across a curious problem. My hygro is going yellow and dropping more leaves than normal. On the other hand, my Twisted Val and Tiger Lotus are growing really well, lots of new shoots and leaves. Which leaves me a little stumped... Hygro's supposed to be pretty hardy - I've normally had to cull it to stop it taking over the tank. I've put substrate in with me gravel to give my plants some life, but I don't have CO2 or fertilizer in there (not wanting to get too expensive). I've got the lights on just over 12 hours per day. Tank parameters are perfect, except the pH is a little high, but consistently so. I did have a wee algae infestation a while ago, but that has resolved thanks to a new GBA. Could the algae have killed off the leaves it was previously on? Any ideas? Help much appreciated Cheers L Report
February 9, 200719 yr comment_146780 i think it will be a lack of iron or magnesium. any way a fert will fix it. Report
February 9, 200719 yr Author comment_146786 That's great, thanks. Any recommendations for fertilizer? Report
February 9, 200719 yr comment_146857 at the moment i just use a cheap thats $2 a bottle, its jbl. its for 200l. also some co2 would help you could make a diy co2? Report
February 9, 200719 yr Author comment_146942 I could probably make a CO2 unit, although laziness is a factor!! Report
February 10, 200719 yr Author comment_146996 So it's not the lighting then - how can I tell if my lights need changing or are not strong enough? Thanks in advance Report
February 10, 200719 yr comment_147004 what kind of lighting have you got? how many watts and how may liters? Report
February 10, 200719 yr Author comment_147024 I've got an AR980, so about 220L give or take, and it's got 2 x3 ft bulbs from the LFS (they're those standard gro ones and one's better than the other, it's got a red tint) and a smaller odd-sized one, perhaps 2 1/2 feet (?). It got the original bulb in it (I got the tank second hand. I've fertilised today, so fingers crossed that helps some. Thanks L Report
February 10, 200719 yr comment_147116 i have a ar980 that is quite heavly planted too, i have a co2 setup running on it and also got good tubes for it and also added an extra 30w tube under the lid were you feed and the plnats grow crazy! Report
February 10, 200719 yr Author comment_147139 So generally the lighting isn't sufficient? Mine's about 2/3 planted. I went to bunnings to get new bulbs yesterday but now they don't sell 3ft anymore! SOG next time, I guess Report
