hi all as in the title what is the opinon of the tunze power heads against the koralias?
i have 2x 6045 and 1 modded 6025 but they seem to be quite directional in flow and cause localised diturbance rather than spreading it out is this the case with the koralias (or all powerheads in general) also is it better to have a few small powerheads or a couple of more powerfull ones.i have a 200ltr 3ft tank but i just cant seem to find a flow that im happy with or one that doesnt blast the crap out of one end of the tank.
at the moment they are positioned opposite ends with the two 6045s facing the modded 6025half way up the glass aimed at the suface.
would it be better to have them aiming accross the tank in different directions and use a nanno to break the water surface?
would this give enough suface aggitation?
cheers john.

yeh all pumps give a simular flow pattern , you wont need the big powerheads for that size tank , you just need to keep playing with the position of the tunze's till you get it right maybe aim one half way down the tank at the back pain of glass so it circulates behind the rock work you'll get there

i use the korallia's, and although i haven't used tunze before...i'm happy with mine at the moment 2 x 2's combied with my eheim return pump on a 225 litre display and everything seems to be good - accommodates for SPS, LPS and softies i think given the choice, and money, i would opt for an MP10 or 20 and just turn it down

I had 3 koralia 4's too them out and replaced with 2 Tunze 6100's.

Cant praise the Tunzes enough, pug ugly though

Think i would go with the tunze over the Koralias but if needed add a Koralia to the Tunzes.

I have a 3x2x2 with 2 Tunze 6060 (6000 lph), Aquabee 2000/1 (2000 lph) behind the rock at one end and an Eheim 1250 (1200 lph) behind the rock aimed towards the surface. Sump return is OR2500 (2500 lph) but with height, I would say it's pumping approx 1200 lph.

Hi, Ive had Koralia 2's in my tank but changed them to tunze 6025's as they are smaller within the tank as I have a 110 litre set up. I have to say the Tunze's produce a much stronger flow than the Koralias. The Tunze's are by far better in my opinion and I wouldnt change back to Koralia after my experiences.

sorry to jump in on the post slappy u still running a tank where are the pics of this masterpiece come on show us

[SLAPPY]

Yep, still running a tank.

Running a new batch of salt as had nutrient issues so dumped all the water and threw away all of the old salt as a safeguard as I couldn't pinpoint the cause of the nutrients, new membrane in RO along with complete new set of RO filters.

Next to go in the bin will the Chaeto, phosphate resin, sand, calcium reactor media etc as the sump is currently not circulating around the main tank as yet.

Fish and what's left of corals are in the sump at the moment.

And no, there will not be any photos until after this tank has been running for at least 3 months.
