Ok I read that article and several other on here and around on the web. If understanding right I can just use the poly fill and change it when it gets dirty. I don't need to use the carbon unless medicating or suspect have chemicals in water that aren't supposed to be there. I will see about picking up some poly-fil today when in Owasso.
Also do I need to add some kind of extra bio material to the bottom of the filter if so what should I use?
As soon as I am able to I will be getting another filter probably will go with the SunSun but will be the 304B can't hurt to go bigger.
I am looking into adding more fish but currently wanting to get everything setup first. Atleast with the filtering and some plants for hiding and things.
The only time use carbon is when I'm using hospital/quarantine tanks. As for bio material I use seachem pond/matrix and eheim substrat pro.
If you plan on getting the sunsun, I would use that as your primary bio filtration and use the HOB for mechanical.
I would wait till you have the other filter hooked up and is mature before you change all your media on your current filter. If you replace all your media with polyfil you may go thru a mini cycle. If you haven't already, buy a test kit (amm, nitrite, and nitrate) to check your water. I'm worried that since you have carbon in the filter, your tank isn't fully cycled. How long has this tank been running for? Did you cycle it before adding fish?
Ok I am looking into getting the SunSun 304B but I have question about it. Does the UV light work on it as far as keeping algee away cause I don't want to deal with it lol. Also I have noticed my fish digging up sand with mouth and moving it and caught them wiggiling bodies at each other last night as well as seen them lip lock for a sec or two. Does this mean they are gonna spawn cause not really ready for that but if do will make myself ready for it I guess lol.
On lighting I am trying to get the shimmer effect and was wondering if could use the CFL bulbs to do it with a clamp light? I currently have a 10.5" clamp light which when hold above tank it does give alittle shimmer but I am trying to get it all across my tank and wondering if would do better if used a smaller style clamp light and just putting about 4 of them up? What do you guys think.
UV will help controlling free floating algae, but you will still have some algae growing on the surfaces in your tank. I don't mind it though because it makes the tank look more natural and help your water quality a little. I don't see a problem with the adding more clamp lights, it should work. LEDs create the shimmer effect pretty well and are very efficient, but they can be pricey though.
