powerhead placement

I've had some trouble getting even flow in my Max E 260 and I'm currently fighting a Cyano outbreak so looking for advice. Currently the bulk of the flow is coming from two Tunze 6095s at the back of the tank pointed at each other. I have them controlled by my GHL profilux to create random...

I have had a Cyanobacteria outbreak and have seemingly good water parameters, granted my tank isn’t the most stable because it is around 3 1/2 months old and fluctuates, I have siphoned most of it and a water change, and will get chemi clean if it persists for a while, but I was wondering if my...

Hello everyone, I've setup my new tank with CaribSea Special Grade sand (not a fine substrate). I have 2 Ecotech mp60s on either side of the tank, and 2 Ecotech mp40s on the back of either side of the tank. Is Reef Crest mode too harsh for those types of corals? Would Lagoon or Tidal Swell...

Hello fellow saltines, This seems like such a newbie question but I can't find any threads with suggestions (maybe my search parameters are wrong). Anyway, I have a 5g and recently installed one powerhead on the long side of my tank. It's mounted just below the surface but I have it pointed...

Hi .... built my Evo 13.5 with a SICCE Syncra Silent 0.5 return pump. I've been told that a wavemaker / powerhead is needed to maintain good flow in the tank. Im seeing that food settles on the substrate after 30-40 sec but that could be move of my placement of the two return outlets. (1)...

Hi all, I have a 5x2x2 tank - running for a couple years with two Tunze powerheads, one at each end. I need to perfect my flow, it's sort of just a brute force setup right now. I realize "flow is different for every tank" and "you've got to play around and find what's right for you"...

I’m currently planning to set up a 120g mixed reef tank. I’m looking at setting up 2 opposing Reef Breeder RP-Ms rated at 2600 rpm. They will be running one of the programmed settings, so my thought is I should credit them with about 50% at any given moment. Because of this, I’m thinking I may...

Hello everyone. I’m new to reefing and was curious about my Nero 5. I’m sure it’s probably overkill for my 20 gallon cube nano but purchase has been made and there’s no going back lol. What kind of flow rate should I be targeting for? I plan on keeping a mixed reef. I’m sure there’s plenty to...

I'm upgrading to a Gyre and wanted to set up the powerheads on each side of my rock work along the back wall of my tank. The magnets would have to be submerged as it is an AIO with the sump on the back. Are they okay to be submerged or will they rust and possibly leach?

I've had my 54 litre tank for a few weeks now and introduced a zoa and a gsp. I was wondering whether I've put my powerhead in the right place? (Bottom right in pic - Fluval CP1 1000lph) The zoa is right in its path and closes up sometimes (left on purple rock). Should I swap it around with...

Hello reefers! I'm looking to up the flow in my monster FO(WLR) tank. Most of the monster threads I've been through are using somewhere north of 4x 4000+gph powerheads for flow, granted mostly for reefs. Currently I have this (controlled water flow shown along with a rough aquascape. Tank is...
