Basically you grow macro algae there as a way to absorb nutrients and trim the algae to export the nutrients as they are locked up in the algae. Lots more to clean but a good place for pods. A fuge requires slow flow and lighting. Best if lit revers of the main tank to help stabilize PH. as it will drop in the night or dark hours. You can also reverse light your sump for the same affect on the Ph.
you have to be very carefull which algae to keep in a refuge. if you end up with Caleurpa it can go Holocarp on you and wipe out your entire system. Halimeda can also do this also. you need to stick with Gracilaria spp. if you want to do this.
BTW- if it grows in the refugium, why would it not grow in the display?
Cheato is the most popular macro. It doesn't go asexual on you. You can usually get it for free from local reefers in your area. A good nutrient exporter, that pods like to hang out in. I always get my hand in it & give a good shake once in a while. Releases all kinds of pods to get pumped to the main tank.
when trying to grow macro in a refugium, do not be discouraged if it does not grow. this is a good thing. it means your water column is low in nutrients anyway. the object is to use it for nutrient export. do not feed the tank just to get algae to grow. at some point if you have a SB than the nutrient levels will become high enough to support algae in a refugium.
A little on/off topic, but....I used to always cover my overflow w/ styro-foam for two things, sound reduction and to limit light so as not to get so much algae growth in there. I now have a durso so sound is not an issue!
So lately I've been thinking:doh: .......maybe it is good to let the algae grow so it can help "eat/use" up some of the nutrients and then I can clean/export the algae in the overflow when I do my WC.
Seems conceptually light a fudge for export w/ out need for a fudge! Good bad/???
you are thinking along the lines of what an algae turf filter or ATF is. large plates that are allowed to grow HA and harvested every now and then to remove the bound nutrients. these are a very effective filter if you have a SB.
Hey guys, I ordered 10 Mangroves seeds to put in my sump. From all I have read, when they get their roots going, they can take the place of a skimmer. And they help in water quality and <!--StartFragment -->Oxygen levels go up faster! Has any one tried them yet?
Mangroves are an interesting filtering method. they are a bit more difficult than you think. i believe it also takes a 10 mangroves per gallon to effectively filter the tank. when growing mangroves it is very important to keep the salt from building up on the leaves. if you do not they mangrove is forced to ditch the leaves. if enough fall off it will die. it is also important to make sure you remove the leaves before they fall into the water. removing the leaves acts as a nutrient export mechanism.
hey guys, im new to this and im gonna try and make a 50 gallon tank. Dimensions will be 36x20x20. I am also going to get a smaller tank that i can pic up from petsmart or petco which ever for like 12 dollars to create a refugium.. Can someone go over in detail on what equipment i will need for the whole system and how you can grow natural food for the fish to eat.
