Sorry about the double posts. I'm using an iphone and a bit new to this forum thing. But I did feel that they were different questions that's why I posted them in different sections.Another duplicate post to this one...
If you're running them 8-12 hours a day then that is why you're getting algae. Also how long has this tank being running and when do you plant the plants?
Please only post one thread and not duplicates. It makes it hard for people to help you when you have multiple posts scattered everywhere.
IMO I would start by shortening your light cycle first and see how that works for a few weeks and see if there is any improvement. The thing about this hobby is patience. If that doesn't work then try to hang them a little bit higher. It is kind of hard to tell without seeing the actual fixture itself. If you could post a picture of the fixture then that might be able to help others. Is there no part number or anything on the fixture anywhere that you could good to try to find out what kind of fixture it is? It is really hard to say if it is to much light, lack of macro nutrients combination of both. I mean if this fixture came with the tank and the previous owner was growing plants in it you might want to ask him if he ever had this problem. It is possible it is to much light but shortening the photo period should help some.I'm going to get a timer and set it for 8 hours. I'm sick of trying to remember to turn it off lol.
I still think that the light is burning my plants because it's only the tops of the plants directly under the lights that turned brownish black. I really wanted to get more information about the light, but I guess that might not happen. Should I just buy new lights (and spend more money :icon_roll lol) or try to make these work? Maybe I could hang them a little higher away from the plants. Hopefully there would still be enough PAR at that height to grow plants.
Well I don't have the slightest clue so your guess is better than mine lol.The pinholes are a deficiency, maybe potassium. The top growth looks like natural color change along with crumpled new growth, which is caused by a few things. It could just be acclimation as Texan stated, I personally just watched newly arrived rotala stems do this in my tank, and for a day or so the new growth was crumpling into a slimmer form, and changing color according to the new nutrient and light source. This all comes from what I can see in the photo but obviously can't see them in person so take it with a grain of salt.
Another reason for crumpling is calcium deficiency, if you're low on GH and not adding a booster, you may very well be deficient in Ca Mg and K.
I have more 300 snails in there. Lol there are to many to count, no exaggeration.There's no way snails are causing those pinholes, if that's what you're getting at. More likely, the plants are robbing their lower portions of nutrients to make up for a deficiency. Study the formation of your decay and read up on identifying deficiencies. Also, when acclimating the stem plant /environment don't "want" the lower portion anymore and it will waste away to release the healthy portion, and often send new shoots from the base if the root base is healthy and receiving light.
Oh yea, I cut way back. It's only going to be on 6-8 hours like suggested. It looks like it's pretty much all of the plants that have the color at the top, to some effect. It's entirely possible that it's supposed to be purplish because I don't know what plants I have. Lol they came with the tank.Patience is your greatest friend in this hobby and is greatly needed so get to know it well. Sudden and knee jerk reactions can sometimes cause more problems than good.
Hanging your lights certainly won't hurt but like already suggested you need to cut back your photo period for starters.
What is the plant that this is happening to or is it all of them? Is it possible this species of plant has purple or red tops that you might not be aware of?
