this tank is looking packed compare to a few pages back!
I've added seven pieces in the last couple of months and moved quite a few bits around as usual, plus my acros do grow - just bloody slowly atm
hopefully Area 51 is open in six weeks time - I'm planning a visit !!! Ask Dom ;-)
I can't ask Dom, he's in a Vietnamese hospital being treated for monkey rabies apparently...............:reading:
Has Dom made you aware of the security clearance requirements in order to gain access to the acro cave Nils ? You can get the medical at your local doctors and have them fax it to me, a chest x ray isn't mandatory but it would show a certain measure of commitment on your behalf......... :beer:
Anyway, i think it's you who needs to be talking to Dom Nils :thumbsup:
You can see i was able to drop the gyre a full bracket height and now the left island is getting surging backflow from the gyre. Any further than about 6" above a close acro and the flow is very minimal.
I run the gyre on 70% at 5 second interval pulse mode and have an RW-15 beside it on else mode at the lowest power. If i run the pulse for any longer than about 8 seconds it blows the sand away from the peninsula end display window five feet away. Remember my display is 32" wide and i ran it fine with just the gyre for a week but added the RW-15 to make the gyre have a big surge every time the RW-15 ramps up to 100% during its cycle on else setting. It points parallel to the gyre and simply provides a random boost to the gyre effect.
The main thing about the gyre to bare in mind is this. As soon as you add a pump that actually interferes with the effect such as blowing across the gyre flow stream, you lose the actual magic. It takes the gyre about 30 seconds running before it settles into the full flow effect. If you block the build up of pulses with a single cross blow from another pump the process has to start all over - and it never will because you have other pumps repeatedly interfering.
This is what i was doing when i first tried adding the gyre and i wasn't seeing the 'magic flow' talked about. It wasn't until i saw Ryan say he was only using the gyre for flow on his peninsula that the penny dropped and i turned all the other pumps off for the first time. I've seen quite a few guys on here running more pumps than they need to in conjunction with their gyres just as i was doing so please dont get offended if you are.
I'm just bringing it up because i think a lot of reefers haven't realised they can do what Ryan and i are doing - you just gotta have faith..........:beer:
Proof is in the pic so if you like your flow now go ahead and run what ever you want
If you would like less pumps and more delicate growth on your acros then i'd urge you to experiment as you'll be pleasantly surprised. It lets you have a shallow sand bed no probs btw and Flo is pushing hard to make sand a requirement for CCC membership......... up to you guys :smokin:
My new sump is almost ready - 1650 x 600 x 350mm - 800mm frag section lit with 8x24W T5's. Water in bottom left then twin socks - skimmer - frags - 2 x matrix media chambers - twin socks - return.
