Hey everyone, so as you may know from my previous blog posts, i have a huge algae problem. But, theres also a few things that aren't that balanced in my tank other than the water quality. I've got (other than algae eaters) neon tetras, cardinal tetras and some rummy nose tetras in my tank. And i've noticed that they mainly hang out at the bottom of the tank and it just creates a really bad look as if they are crammed at the bottom, but they actually have a whole lot of space above them. like…

So, because of my huge algae problem (my previous blog post, check it out need help!) i bought 6 otto catfish for my 17.5 gallon (66 liters). they are really helping, but just in one spot, they bottom right hand corner of my glass. what do i do to make them spread out to clean all over. they don't seem to be munching at the algae. just sticking on the glass. not taking care of the huge algae pieces. ANY TIPS?

So it's been a couple of months since i've had this enormous amount of green filamentous algae in my tank and it's really gotten to me. It's everywhere :plants, rocks, wood, glass, tubes, snails. i REALLY NEED SOME HELP ON GETTING RID OF IT!

So i've got a 17.5 gallon tank, heavily planted, not too crowded fish wise. I'm using the EHEIM professional 3 filter and dosing daily Co2 (my ADA cO2 advanced system now has a problem so i am barely dosing any now any tips?)  I dose a fertiliser…
