" I only use Chaetomorpha. It grows and I remove some then it grows more" Your referred to this Chaetomorpha could your please expound on that a bit? is this this the typical plant that grows in the refugium or is this a completely different component. If this is the plant then I there is no...

That was very interesting information regarding PH, this is exactly what I was looking for. Unfortunately I still am fuzzy on the links of other factors to balance PH, I guess I mean to say what has the most impact on PH and the 2nd and 3rd factors to look at when PH is out of balance...

lots of info there really good. So sand beds, is this the sand in the refugium or both sand in the top and bottom tanks, and for a 75gal system top side how deep is a sufficient bed. top and bottom? 2nd question where does the good macro algae come from? does it spawn naturally or was it...

Ok I thought Alkalinity is pH? above statement says: "If Alkalinity is in a good range and PH" the and in that statement seams to indicate 2 different things. Confused here. So doing water changes is one method to reduce Co2 in the water? I still have not got a clear answer on how the pH is...

Thank you again for the help. Permit me a question or two more. So calcium should be low that's what I gather. what I did not pick up is what level should calcium be at (measurement and value) Do I want any calcium or as little as possible what? The last question is a rehash to understand...

Well in this case I am starting the whole system all new. So I will not add bio balls. What is the benefit of not adding those if I can ask?

Wow it seems everything I was doing was wrong. I was buffering my water with Kent Marine pH buffer every 2 weeks. I eventually quit doing it because I noticed no change in pH ever, even well after I stopped buffering. So many questions now. Please expound upon your statement about pH buffer is...

I am still confused a bit. In the refugium I had (created by a professional aquarist) it had 3 chambers the first chamber was the dump with bio balls then it flowed under a wall into the bio chamber with the plant and light from there the water spilled over into a clean chamber where the...

Can someone define what a sump is. Is this different from a refugium? Also, what are these seachem matrix bags that were spoken of? Does a FOWLR need these or are they just a bonus?

Great to Hear, Last time I purchased a full 50 Lbs of live rock and it killed my wallet. So when using dry rock what can be used? Granite, limestone, lava rock, flagstone? what is best? Aslo is there a way to create dry rock such as cementing new rocks then let them sort of season in a...

So given what you said about Nigrogen levels and pH relation. Does one still need to buffer the water with pH buffer?

oh gees, I see it now thanks

well for those who don't have access to a lab or don't have a way to test pH as you do, what do you suggest? If all we have are the liquid test kits how can we trust our results if what you say is accurate? Are you really saying that we really can't truly know the pH of our system and the...

Hello, Is there a search available on the forums? I would like to search topics and not pester everyone with the same discussion you most likely have answered a hundred times. I don't see the search bar or box.

Are you saying that even a 2x2 -3x3 size yellow tang is to small for a 75 gal? Even if its the only tang in about 5 small fish total?

Define dry rock please.

Ok, nice to get a reply. I was going from memory on that Temperature. If I was to put money on the temp I ran it around 77-78 deg. I was told that this was the optimal and if I got up in to the 80's I would stress the fish. From what you have told me this is not so. I had really good water...

Hello, I am going to start up my salt water aquarium again but before I do that I would like some answers and feedback. I previously ran a 75 gallon tank with a 30 gallon refugium and an Octopus skimmer. Nutrient Light in the refugium and non-Nutrient light up top. I had a Fish only tank...
