[raubiy]

Yea its time to double Uv.
I'm moving fish from 220g to 600g. My head is spining. I have so much work. I'm moving to new hause....

Option A-----------------------------------


Option B------------------------------------



And i like to know whay is one better. Or maybe option C.
I know here we have some amazing people that know this stuff.
tnx for answers

Your question is simply stated as "in parallel or in series" and the answer is in parallel. While either setup will give you about the same contact time in the UV chamber, you will have less turbulent flow in parallel, and it allows you to service one unit while the other continues to operate (assuming you include the proper valving). Also, if you do go with the series option, it looks as if you were planning to end with the filter? Filter before UV, always.

Yes everything will be conected with valving. Like i have conected right now.
Canister filter is completly cycled 5-6 months now + i have another 2 canister filters on this set up cycled for 1.5 years.
I will add anothes 2262 full with seachem matrix. I'm thinking this is enaught for 600g. Fish will be the same. Bio - waste the same. I'm going to just move them...

Right now is conected to 1 36 uv unit. I'm going to move everything and just add 1 more uv in parrarel mod.
This is old pic Left side filtration On right side ia just 1canister.
Thrank you for answer. I'm going with parallel

consider getting some distance or angles between the UV chamber inlet/outlet before connecting to plastic as the UV exposure will degrade the plastic over time. The only good way to do that in this setting is with stainless steel fittings, which can be expensive... you may want to consider using a section of plastic that is easily replaced every year or so.

Looks like a stainless band on a plastic tube... UV is on the same inside, so this won't help

Aren't most UV's made from PVC?

 

[BrookKeeper]

No, most UVs manufactured for legitimate long term use (on drinking water supplies) are made of stainless steel. UV systems made for aquariums are the only ones made from plastic.

Those stainlessstel uv for drinking water are extra expensive. Price is high but quality is top. I have seen few.
Right now not for my pocket
