RAV-65's Reef Haven...

Somehoe these sort of thing will get into your tank

There's no escaping especially when you have a refugium where they can bloom

Just wanna keep it simple ... so maybe wun be keeping so many organisms in my sump... intending for brittle stars and sand dollars niah...

[blueheaven]

In that case, watch out for signs of too big an anaerobic region

If next time you want to remove, it'll be a problem then

Anybody used Sequence?! Maybe a good pump...

Hi RAV65. The 2 Sequence DARTs I'm using are relatively quiet compared to the single md55 I'm using to drive my beckett.

You're welcome to drop by to have a look for yourself if you'd like. Just give me a buzz during the weekend. Cheers!

Hi Bro,

Just received my Sequence Dart today. Sorry, cannot comment anything yet. Let you know in a months' time. Cheers.

[RAV-65]

Daimy068 & dsam.... would indeed be grateful if the two of u can give sone feedback... hopefully they are quiet pumps... but still very concerned about headloss...

Are the pumps hot??

[daimy068]

Hi RAV65.

With regards to the headloss, do take note that the DART is not pressure rated. Headloss will depend on the length of piping run (taking into consideration vertical climb as well as horizontal run), number of elbows, ball valves, etc.

The pump has cooling fins which dissipate heat from the pump. I have added cooling fans on the bridge which is situated above the pumps for my FR.

Hope the info helps.

Cheers!

Thanxs bro!! Your tank really complicated siah... see liao also blur...

u wldn't wanna see weisoon's setup then.

[RAV-65]

No wonder!!!!! Weisoon got a hand in Daimy068's setup!!

[weileong]

pls confirm that the DART has no cooling fan.

If there's no cooling fan then I guess the noise level should be much lower.

[daimy068]

Yes Weileong. You've got a point there...DART has no cooling fan...only cooling fins. Well thought of.

Not much space with the huge beckett right in front. Good thing my 9yrs in the RSAF prepared me for working in confined spaces...this is just like working on a helicopter.

And another 12 years in gymnastics and yoga right??

seems like DART another choice for consideration.

How abt the noise level and heat? Can use your hands to feel?

One slight problem is the intake which is 2", need to use giant bulkhead

Huh? Didn't know the bulkhead 2".... lucky u mentioned.... Damn... still cant decide on wat pump to use...

[weileong]

2" bulkhead still quite okie provided you plan properly.

[daimy068]

Cannot feel heat coz got a fan blowing directly onto the pump but have to say that the cooling fins do a good job in dissipating the heat even without the fan.

Vibration-wise, mounted the pump onto a wooden board and layered with vibration absorbing rubber mat. Also have flexible hose section at the intake portion so as to prevent any vibrations from getting into contact with the sump manifold which might cause that area to crack.

The DART comes with a 2"-1.5" reducer. However, take note that this is the max allowable reduction so as not to induce stress on the pump. Also, the threads on the reducer are for American Schedule standards so the Japanese JIS standard thread on your male adaptor (if you're using JIS standard) might not mate perfectly. This was the reason for the leak when I initially connected the pipings. What I did was apply silicon sealant (not too much though) onto the threads itself and now, no leak.

Hope the info helps.

vincent, saw u ordered 400W instead of 250's , change of plan huh ?

Good writeup bro... now, the big question : Anything bad about the pump??

[RAV-65]

No lah bro.... ordered wrongly... amended liao...

[daimy068]

So far, none leh. Have to say I'm very satisfied with the pumps up til now.

Good good... so my researh continues...

Tank Update:

after 24 pages of informative and constructive discussions... the tank is finally being built... hopefully it'll look good!

Will posts some pics as soon as I have any!
