Fluval Spec V Filter output Mod
I recently set up 2 planted Fluval Spec V's for housing a single Betta or some shrimp...I haven't decided yet. After fighting with heaters for a couple of days and then reading how to put some small holes into the pump output tube, I finally got my temps stabilized. Then came the small problem of pump output. The output is incredibly strong for a Betta or small shrimp. I tried putting some Fluval pre-filter sponges on the output, but that didn't satisfy me as I quickly built up some proteins on the water surface. It also made my temps drop suggesting that my flow had changed in the pump housing. It did indeed slow the filtration down. I tried placing a small piece of coarse foam into the nozzles and that worked until they became even slightly clogged. Frustrated I started digging around in my filter scrap boxes. Eureka! I found something that would work for me. I used to breed shrimp and was a huge fan of cheap foam filters until I discovered the Hamburg Mattenfilter. I tore apart one of my old filters to find the part I needed. This fits perfectly over the end of the filter tube coming out of the pump output to the tank without any modifications. Just remove the swivel output part and replace it with the part indicated in the photo's. The opening is large so it will not spray water straight into the air. I turned my pump all the way up as well to see if it would hit the ceiling...but it didn't. It sounds like a waterfall but I like that...some of you may not. I filled the tank just over the output. There is still no real splashing. It is pointed straight up in the air, so it will move the water surface good but not affect the flow of my plants or fauna. I have made spray bars for this as well, but I really do not want to alter the interior of the tank, so this was the best solution I could find for now. Surface agitation without spray bars, air stones etc.
Hope this helps someone,
