flow

On Monday I changed my mp40 schedule from short pulse all 24:00 to twelve hours of pulse thru the dark hours but thru light cycle having two hour intervals of reef crest and nutrient transport alternating. When I say the flow was strong, i mean it was mayhem in there. I should have taken a video...

Currently have algae build up in the sand bed. Po4 is reading 0.0 but was steadily running at 0.7 prior to this. With the algae growing I don’t think it’s truly 0.0? Running a 400gph return with rotating random flow nozzle and a slw 5 100% on random/else mode. Would appreciate any feedback or...

Hello everyone. Right now I have the Redsea Desktop which is a 15 gallon display and 18.5 gallon tank. The video is attached to show the current flow. If you do have too little flow what is a sign to look out for as well with torch corals. This is with the lights off so the polyp extension is...

Hey! So I have this Duncan for about 2 weeks and still don’t really know what’s the quantity of water flow that I should have on him. Here is a video on how much flow he is receiving, should I increase or decrease the flow?

Has anyone used this before? Seems like a good idea on paper...but I'm not sure how it would work with the magnet... I really hope someone has experience with them! https://www.ebay.com/itm/205180440613

Is this too much flow? Just got it!

Hey all, most of my acros have limited polyp extension especially during the day. Some of them had much better extension when I bought them and they receded once they were put in my tank. Most the ones I am concerned about have been in the tank for anywhere from 3 days to maybe 3 weeks...

Just wanted to get an opinion on flow for my tank. I'm contemplating between moving my powerheads from the side to back glass. I currently have 2 Nero 5s and 1 Nero 3. The 5s are offset at the first and second 3rd of the tank (front) with the 3 at the last 3rd (back), if this makes sense...

Trying to plan out what to put where on these shelves

Hi I got the TMC Vector 850 It’s has a max flow rate of 674gph When reading though other UVs they all had different recommended flow rates for different purposes. Anyone have any idea what they are for the TMC Vector 850. I am running 460gph at the moment.

Hey everyone, I'm coming back into the hobby again after about 10 years and I'm super excited. I've had the opportunity to inherit a tank 215g (72x24x29) from my retiring uncle and need some advice on what to do. I've already gone ahead and broken down the tank, storing the rock in trash cans...

I have a Reefrun 7000 in a 750 Max G2 (roughly 198g). I’m currently running the pump @ 50% but wondering if it should be running at a higher rate. Would love thoughts from others on turnover rate

What is the best way to aim a Gyre-style wave maker? I have an Ice Cap Gyre 2k in a 40 gallon breeder on the right side. I'm using the "LPS Reef" pattern on a Hydros Wave Engine. The flow goes in a circular pattern, but I feel like I get a lot of detritus buildup on my rocks and sand. Is this...
