OK lots of possible things here:
-long green strands are hair/thread algae, not beard. Hair/thread algae normally is easily removed (not connected to the plants its growing around/on). Staghorn is a nasty black algae that is practically glued onto the plant leaves and will not come off without damage to the plant (we normally just recommend clipping the affected leaves and removing them from the tank). BBA is a very fuzzy looking algae with tightly packed bristles that like staghorn will not come off easily (again most recommend just clipping off the affected leaves). In both BBA and staghorn a fluctuating level of CO2 is normally the culprit. Are you injecting CO2 with a DIY setup? That is one of the most common symptoms.
-your BGA tells me one of two things, either you have a dead spot in the tank where the flow is low (a common occurrence in heavily planted tanks, which can be remedied by adding a PH or changing the location of the HOB or canister filter intake/outputs),
OR, you have low nitrAtes. The nitrAte test kits we have are very inaccurate at low readings (10ppm and below). This could be responsible for both some of the other algae and the BGA. I would recommend increasing the dosing of your nitrAte and see if that alleviates some of the issues.
-the brown stuff sounds like diatoms. If your tank is less then 6months old its not a problem, just let it go. It will slowly kill itself when it runs out of food. In the meantime you can keep your plant leaves clean by gently rubbing them. I only recommend this for slow growing plants with few leaves (like anubias), as the faster growing normally don't get diatoms or more damage is caused by trying to clean them then its worth.
-Lastly for pictures I recommend an outside source to host the images. I personally use
www.photolocker.net as it was recommended to me by a member on here and I've never had a problem with it. Once you setup a free account you upload your pictures to the site and then right click on the picture and select PROPERTIES. You'll then see the url (
http://picture). You copy that url into the img tags here and it will display in the post. So for example I have a picture called fish.jpg. I upload it to photolocker and right click and display the properties (or even easier if you have a "copy image location button when you right click, sorry I use Firefox and don't know if your browser has this option). It says the picture is located at
http://photolocker/mypictures/fish.jpg. I then post my message on aquarium advice and where I want the picture I push the Img button next to the List= and
URL buttons (along with bold, italicize, etc.).
So your message should look like this:
I really love my fish. Here's a picture:
I added an extra space after .jpg so it would show you what I typed but when you want to actually put a picture in you don't want any spaces between the
