filter for 125 gal fresh

dont scare me

the air was from the spray bars little holes shooting water into the tank.Or at least thats what im thinking.I have changed the spray bar to the jet nozzles so there is no noise and no tiny air bubbles.But now im told I will need airstones to break surface water since I removed the spraybar.

Should I still be concerned with air in the lines if the jet is not producing bubbles?
Could there still be air in there?

Is there any other signs of air in the lines other than bubbles?
 
If your jet nozzles are not shooting bubbles out of them, it is safe to say there is no air in the lines. I'm not quite an expert on the subject, but to the best of my knowledge, with sufficient water movement no airstones are needed. Anyone please correct me if I'm wrong and why...
 
the reasond to wanting more oxygen

spydrkss you mentioned with sufficient water movement no airstones are needed believe me im no expert on the subject either but I read somewere that the biological filtration in a canister filter competes with the fish for oxygent.In fact im posting a new thread on that.
thanks
 
Did the article or research stipulate why it's just the biological filtration in canisters that completes with fish? I'm definetly interested because I get most of my bio filtration from the bio-wheel and the undergravel system... I haven't actually put any media in my canisters that "promotes" large bacteria colonies. Please let me know when you get a chance. Thanx!
 
Sounds like you have enough filtration and then some on that tank. It never hurts to over-filtrate a tank but it DOES matter if you're under-filtrated. I can't remember the last time my water was anything but crystal clear.
 
If you are happy with your water clarity and your testing reveals good water quality, you have no need to add another filter.

That said, it won't hurt, and a canister is a lot better at mechanical or chemical supplementation. It would give you some more flexibility, and allow you a place to plumb in a UV sterilizer if you ever felt the need. In the past I had been a fan of using a HOT magnum weekly or so for a few hours. They are extremely simple to set-up and take down. Particularly helpful with messy fish, and fish that eat live foods.
 
jagarundi thank you thank you!Thats what me and my wallet wanted to hear!

spydrkss I cant remember wich one of these forums I read that in sorry.

Why slojim why?! Just when I thought I my tank was up to par you now say UV sterilizer.
slojim that may be the next step if you guys really think I need UV sterilizer.
The model here is the more the better I get it but do I really need to add a UV sterilizer.
OK OK,
1. How much does a UV sterilizer cost for a 125 gal tank?
I better sit down for this give it to me easy.
2. What does it do?
3. Do I really need one

A UV sterilizer is purely optional. You don't really NEED one.
