Thanks so much, for the input. I went for the EHeim. I thought i red a lot of bad reviews for the theo and aqueon, but i read so many reviews, im not sure now. Thats why i wanted real user input from all of you instead of relying on Amazon, etc.
Amazon does have a challenge with reviews, and ive noticed lately, you have to check that the review is for that particular item, as it will pull in reviews for a type of item, and apply to the one you are looking at!
I also tried viewing as many pics as i could to see what others had... I did see a lot of theos.
