Hi Mike
At no point was we made aware that our weir system needed to be changed. I did the maths myself and reduced the water height in the aquarium by 5mm to ensure the water line would still be covered by the pelmet and also ensure the small amount of space left in the sump could accommodate the returning water.
I have to admit that this is the first time i have ever come across customers who desire a small amount of turnover (5x per hour) as all our marine customers are aiming for 10x - 15x turnover per hour.
The aquarium will run perfectly well as i left it and will allow for a larger turnover if required.(It will also run silently)
I will readily admit that i changed the return pipe design from that of his existing aquarium but i considered that a must. It is myself who installed the pipework and myself who would take the blame for any leakages, to simply wrap ptfe tape around a return pipe and place an elbow over it is not something i can do or something i would suggest to anybody else to do. I also placed the return pipe at the opposite end of the aquarium to the weir to help create an even flow (this i considered essential considering the size of the aquarium and the fact there is only one weir in the corner)
There needs to be a consideration here for the size of the aquarium we supplied, it is not a 400 litre 4x2 with a small sump. It is running almost twice the amount of water and needs to be installed and piped sufficiently which i feel i have done.
We have built over 300 aquariums this size and bigger and have piped them all in exactly the same manner with a 100% success rate.
I am more than happy to try and fix any issues there are here but i am at a loss to see what they are? I have built the aquarium and piped it to achieve far more flow than was being hoped for? This in 99.9999% of cases would be a bonus.
I feel a bit annoyed with the video on youtube which is trying to portray a flaw in my weir and pipework, there is no such flaw at all.
We always have potential customers looking through youtube videos of our builds and seeking confirmation of the quality of our builds, now when somebody searches Aquariums4life they get to watch a " review" of our weir and pipework published before the aquarium has even been filled, and portrayed in a negative way. This is very unfair, i had no idea the aquarium was to only be turned over at a small rate and that you required such a small amount of flow.
Like i said, i did the maths myself as i was unhappy with sump design and the fact that no thought had been given to returning water, i made changes to the water height so that the aquarium will run how you wanted without flooding your kitchen.
Our reputation is everything to us as we are a small family company, we always try and go the extra mile. If there is anything we can do, we will.
It would have been nice to have had the opportunity to do so.

Sorry, i didn't see the youtube review had been changed.

@Ian Dashfield

My mate Dale in Norwich has one of your tanks which I have seen in the flesh many times and it's only a phone call this evening I asked him who built it as it looked like the one here and he said you guys.
So in my opinion the build quality of your tanks and stands is awesome if I had not already had mine built I would of been ordering one.

When I ordered mine a 6x2x2 I opted to go weir each end and have twin return in the middle I only have a single hole drilled in each weir I don't have any emergencies at all in the DT as the odds of 2 x 40mm durso's getting blocked is nill in my opinion.

I run durso's as I just said above and find them to be absolutely silent.

I'm sure once you and HK sort the minor issues he will be more then happy with the tank as my mate is and im sure he has the same pipework that you have done on this one and his is absolutely silent so may well be worth HK filling it and firing it up to see what he thinks of it :)

@Ian Dashfield (and everyone), I have changed the video to give a better, balanced review, and I've been through this whole thread and edited my comments, and added edits to other people's to explain.



Ian, I didn't see your reply until late on today, and genuinely thought the design was flawed.  I feel a bit of a prat for not just calling you, as after reading your explanation of your system, it all made sense.

The one thing I'm surprised at though is the rate at which you planned on running the tank.  I've done some googling, and looking at conversations on other forums, and there are huge debates over sump flow rates, but 3 to 5 times the DT volumes through the sump is quite normal (although more is too).

I will give you a ring tomorrow.

The DT's about a third full now, with two heaters in there.  That's taken about 12 hours.  Plan to leave it filling overnight and all day tomorrow, and hopefully by the evening it will be close to full.  Then I'm thinking of mixing the salt with my new Jecod DCS 7000 pump.  It should blast the hell out of it.  I'll then start making up some more salt water in buckets, etc.  Next, add the sand (after washing it - not looking forward to that), and liverock and let the DT overflow into the weir and sump.  Then move the sump equipment over and top up new the sump to the brim, and turn on the return.

Anyone see any issues with that plan, or have any other suggestions?

Glad it's full steam ahead :) when you get chance I would like to know the workings of the durso in the overflow just for future reference ;)
Filling method sounds good.

If you have no rock in there ect then just work out how many litres is in there and just whack the salt in for the amount of RO and then fire system up that will soon mix and heat that's how I do new builds.

I mix with a 7500LPH Fluval sea pump and sion mixes 75L in about 25 minutes haha

It's not running through the sump yet. Been away with work, and struggled for time.  Next step is to put my new liverock in (been cured and fed daily for about 5 months), and let the DT overflow.  Then I will do the big move over from my old tank.  Rock, coral, critters, skimmer, lights, the lot. Top up with my old water to add a bit of plankton and save a bit of cash and turn it all on.

Likely this will be Friday night.

It's reeflowers 0.5-1mm pearl white sand.  It's the finest grain I could find, and spot on for the DSB I will be running.  I know it'll blow around for a while, but once the bacteria starts to grow, it should stick and be ok.  Read quite a bit about DSBs now, and lots of others have fine sand like this without issues.

Oh, and that's after 4 hours of rinsing the sand in the garden.  My back is shot!
