I just happened upon this while checking the others posts. I don't know why I didn't receive notifications that I had replies to my post. Maybe I clicked on something I shouldn’t have.
Well, better late then never. lol
"Therefore, I would spend part of my investment money on a good filter, turning proteins into nitrates and so on, and use the rest as a fund for waterchances. "
I would say that the tank has enough filtration for its size (two large filters), but the tank in question is a little over crowded for now. I have three Oscars close to 10", four Managuense's all over 10 to 12" , a large (12"+) Sailfin Pleco and one mutt (6”). A little too much for a 125, but I have to put off setting up another fish room for now.
I do perform regular water changes. I do large scale water changes once every one to two weeks and at least 25% every few days. My water is clear and always tests out OK. I just don't want to starve my fish to keep the water clean in between water changes. I wanted to use the skimmer to take care of the leftover food and the soluble waste in between water changes.
The fish are getting enough nutrition as it is (pellets, freeze dried foods) and I know it’s not good to feed predatory fish every day either, but I like to feed fresh beef heart and seafood. This can cloud the water. I will also make 50 / 50 mixtures of beef heart and garlic. This can get messy but my fish love it.
It looks like you have your filtration set up in a sump. Do you use a wet / dry system?
I contemplated building my own, but the set up I have (Fluval 405 and Aquaclear 110) works well enough to leave it alone for now. I was thinking about one of the commercially available hang on tank models of skimmer.
"Are more frequent water changes possible, maybe you could set up an automated system on that tank to provide fresh water every day or two. Water is not free but a simple water system might be cheaper than a protein skimmer. "
I thought about an automatic water change system. It’s just not something I can do in the rented space that I call my home. This tank is also in my living room. Not an easy thing to do from there.
Since I lost my colony of Herichthys tamasopoensis that I had for over 8 years, I scraped most of the tanks I had and only kept the 125. Since I only have 9 fish now, I condensed them into one tank for the time being.
I just moved last week and I will start the process of building some new racks for my office. I plan on trying a skimmer in the rack system to see how it works.
The only reason I brought this up was the fact that I read about protein skimming for a pond and it worked for the person who wrote the article. I am always looking for new ways to make my tank set ups better and too me, this appears to be a good idea.
Dstuer’s set up proves this.
Bas, Dstuer, Dan, Polleni and Lisa,
Thanks for the taking the time to respond. I value your opinions.
