GobyMan Posted July 3, 2002 Share Posted July 3, 2002 How much current should I be giving to green star polyps and galaxea? It seems I have read they both like "medium" current, but what would constitute medium current? Thanks Link to comment
NaNO ReeFiN Posted July 4, 2002 Share Posted July 4, 2002 For me, medium current would be like blades of grass slowly being blown in the wind... That's how the GSP IMO should look like, blades of grass just blowin' in the wind... (Edited by NaNO ReeFiN at 5:33 pm on July 3, 2002) Link to comment
tinyreef Posted July 4, 2002 Share Posted July 4, 2002 a linear flow of about one foot per three seconds? sounds technical enough to me. :confused: a random turbulent flow is better than a true linear flow like a river. you can gauge flow speeds and direction using bubbles. i've used b-ionic's part #1 mix to examine direction kind of like a wind tunnel effect. it immediately clouds and you can very accurately view the underwater flows. your livestock may not appreciate this so don't do it very often. (don't forget to add the #2 mix) once you learn the flows and speed you can gauge it to your animals. 3 sec./ft isn't too fast you sometimes may need a surge.

GobyMan Posted July 4, 2002 Author Share Posted July 4, 2002 I realize random flows and "bursts" of water are better than a true linear flow, but how can this be accomplished in a nano? To clarify, I have a 5 1/2 gallon tank with no filtration (xcept for live rock and sand) so I use the powerhead I have in there for current and surface agitation. Link to comment
tinyreef Posted July 4, 2002 Share Posted July 4, 2002 sorry, just being specific. how about pointing the powerhead behind the rock so that it flows thru the various nooks and crannies? i'm don't know how it looks so i'm grasping. i've never had luck with the rotating ones but others swear by them.

GobyMan Posted July 4, 2002 Author Share Posted July 4, 2002 No, I wasn't ripping ya, just wanted to offer up a litte more info for people to go on. I was thinking of aiming the flow down onto the rocks, but with no other filters/movement, the surface wouldn't be broken up and I thought that was pretty important for gas exchange, etc....I should probably leave it alone, I keep changing the flow rate every day to try and get the star polyps to "wave" without having the galaxea blown all about....

tinyreef Posted July 4, 2002 Share Posted July 4, 2002 how about hagen's surface skimmer on a aquaclear mini for breaking the surface tension? i'm not sure if they're compatible size-wise though. i just got my mini recently. btw, you can never just leave well enough alone.

NaNO ReeFiN Posted July 4, 2002 Share Posted July 4, 2002 Use two powerheads pointed directly at each other from opposite sides, this should provide unnatural currents moving around the nano instead of the straight flow that one powerhead would produce. Link to comment
Toyfreek Posted July 4, 2002 Share Posted July 4, 2002 I got a zoo-med powersweep 212 Works good for a nano.....you gotta keep em clean. Toy Link to comment
vanillabox Posted July 4, 2002 Share Posted July 4, 2002 I agree with Toy, the Power sweeps are great for making the water current go all over the place. I clean mine once a week, same time as water changes for my office tank. Link to comment
Sahin Posted July 4, 2002 Share Posted July 4, 2002 I have my pink star polpys with just the similar amount of water flow Nano Reefin mentioned in his first reply. They seem to open up the greatest amount set about there too. Link to comment
Guest LudavicoTechnique Posted July 4, 2002 Share Posted July 4, 2002 Poweheads dont need to be cleaned very often, usually when you change your water. Link to comment
