JoeQ Posted January 16, 2022 Share Posted January 16, 2022 Does anyone have any good resources on flow? Particularly one that explains different intake/output configurations and its affect on flow. Im kind of in a tight spot, I have an angelfish so im trying to keep my flow low, at the same time I need to improve it for better nutrient distribution.

Patrick_G Posted January 16, 2022 Share Posted January 16, 2022 I’m not sure if this is helpful, but in my 75gal I have a HOB and a powerhead with a fan shaped diverter angled towards the glass. I haven’t managed to eliminate absolutely every dead zone but I do have decent flow to almost every part of the tank. I mitigate the flow from the HOB by managing water level and using filter floss on the spillway. The fan shaped diverter allows me to adjust the flow on the powerhead. I’m able to keep it at a level that’s comfortable for my tiny K class guppies. To make sure I get good nutrient distribution I dose liquid fertilizer into both flow streams. 2 Link to comment Share on other sites More sharing options...
Beardedbillygoat1975 Posted January 16, 2022 Share Posted January 16, 2022 Some of us use a Hydor korralia pump or a small power head to move the nutrients around that way you can position it so the angels can avoid the flow. Here’s a bit from aquarium science.org https://aquariumscience.org/index.php/9-aeration/ 1 Link to comment Share on other sites More sharing options...
JoeQ Posted January 16, 2022 Author Share Posted January 16, 2022 (edited) Funny you should mention that, I was planning on adding a small powerhead, in the meantime I had to deal with a bad case of protein film first, so I used an old bulky surface skimmer..... In the course of skimming, I discovered the ehiem 350 which small enough to leave in tank, solving both problems and the inspiration for this post. 😂tr Patrick: thanks for that, but without a picture its hard to imagine. I do also use a sponge on my output to defuse the force Edited January 16, 2022 by JoeQ 1 Link to comment Share on other sites More sharing options...
Beardedbillygoat1975 Posted January 16, 2022 Share Posted January 16, 2022 I like those surface skimmers. If I ever go with a no floaters scape I’d use one. Link to comment Share on other sites More sharing options...

It’s looks like a great skimmer and I’ve seen people take the top off and use it as a tiny power filter for shallow tanks. Link to comment Share on other sites More sharing options...
JoeQ Posted January 16, 2022 Author Share Posted January 16, 2022 Petsmart, they are on sale for 32 bucks. You can buy in the store, show them the online price and they will honer it in store. I also got the coral life timed powerstrip that way, its usually 45 bucks, but got it for 20 on account of the online sale 1 Link to comment Share on other sites More sharing options...
