Lugmos12 Posted November 12, 2017 Share Posted November 12, 2017 I fed my tank some seaweed today. A piece of it got sucked by the wave maker and torn into smaller pieces. Now, my question is, how does seaweed effect water quality? Quote Link to comment
Subsea Posted November 12, 2017 Share Posted November 12, 2017 Depending on the macro algae, you may have seeded your tank. You you should qualify your question more.. does the question refer to effects of seaweed when it is growing in the tank or does the question refer to organic nutrients decomposing into inorganic nutrients.

Lypto Posted November 12, 2017 Share Posted November 12, 2017 well, if it's growing, it's removing nutrients and storing it in biomass. if you chop it up and it dies, that's releasing the stored nutrients. some algae leach chemicals in very very small quantities over a period of time, macroalgaes are normally a great addition to healthy and balanced reef. (I feel like I'm selling cereal.) 1 Quote Link to comment

I mean the second part about decomposing. I fed dry seaweed. Quote Link to comment
TheBig053 Posted November 15, 2017 Share Posted November 15, 2017 I am also curious about this. I rubberbanded a golf ball size (diameter) piece of purple dried algae to a piece of rock and put it in my tank for my starry blenny. How long can I leave this in the tank? Do I need to worry about it decomposing? Tank has been running about a month and wast started with live rock. Small bio-load (1 fish, 4 snails, corals) at the moment. Is there good general rule for how long you can leave dried algae foods in the tank? Quote Link to comment
Subsea Posted November 15, 2017 Share Posted November 15, 2017 If they have not eaten it in three days, toss it. Actually, if herbivores are active they should be eating it on day one and you should never put more dried algae than herbivores can eat in a day. I made a Tang feeding platform to provide shade for NPS. This macro is alive and will recycle inorganic nutrients into organic biomass of fish. 1 Quote Link to comment

I made a Tang feeding platform to provide shade for NPS. This macro is alive and will recycle inorganic nutrients into organic biomass of fish. Noted. Thanks for the input. The blenny immediately began picking at algae on the rocks after I finished acclimating it, but I wanted to be sure it had enough to eat, so I added the small piece of seaweed sheet. I'll have to get creative on how to keep the sheet of seaweed stationary if it's only the amount it can eat in a day. I suppose I could only offer it every other day since it does appear it is finding some algae on it's own in the tank. Great looking tank btw. That GSP on the back wall is strong! 1 Quote Link to comment
Subsea Posted November 15, 2017 Share Posted November 15, 2017 Fish should graze, it is natural for them. Three weeks ago I received: three flame scallops; four yellow cucumbers and five Damsels a singing. Sorry, I am getting stoked for Christmas. I ordered a Flame Angel as the “last fish” to go into my 25 year old 75G Jaubert Plenum. He was laying on his side and breathing rapidly in shipping bag. I acclimated and released him to tank. He would not eat and swam erratically. On the third day when the other Drawf Angel in this tank started to pick on him, I would not have bet two bits for his survival. on the third night that flame angel was in this tank, I added several pieces of diver collected uncured live rock. In the morning, with ambient sunlight in tank, everyone was grazing on real live rockS 1 Quote Link to comment
Clown79 Posted November 15, 2017 Share Posted November 15, 2017 Are you talking about nori strips? If so it's best to use a veggie clip or wrapping it around a pvc pipe with an elastic. All uneaten amounts should be removed. This prevents nutrient issues when feeding nori 1 Quote Link to comment
Lypto Posted November 19, 2017 Share Posted November 19, 2017 @Subsea, I have to say the GSP wall is amazing. I've had dry rock that's been sitting for a year sprout dictyota algae, the nori could have little spores left over somehow. I don't really have herbivores(aside from an adventurous clownfish).
