OK, another update, I swear I think my middle name is "Murphy". Bad luck with the UV/Bio Filter. It has to be returned , UV light not working and too much involved to send it to the manufactorer, have them see if it's the bulb, or electrical. As it turns out it was way too small, plus instructions said to only have 50% of pond volumn going in so had to split the flow from my pump, and some other issues. But I guess I'm back to square one, and will try to build my own, again. Water still yucky, and more now that I've been in there messing, but the fish don't seem to mind, LOL A friend of mine did share another big clump of hornwort, so didn't anchor this bunch down, just let it float. I did check out Springdale Gardens website, Sissy, and saw some plants I really would like to have.I just need to keep reading all the ideas on the bio filter, and come up with one that would work for me. The one I built before, was so big, and the outlet was up so far that it was impossible to "hide" So back to the drawing board..
