I’m into buying Spottes’ Captive seawater fishes, and have a question about its content. I looked at Amazon.com and see the Contents and it says “Notes and references” 220 pages! What is it including, not just a reference list I guess? (The book contains almost 1000 pages, but from the Contents...

I have run my reef (700liter with a SB over plenum in the sump (1-3mm grain, 40x50x10cm) and a fine 5cm SB in the main tank) for three years: During that time I have had constantly low calcium (300-350) and quite low KH as well (7-9). During the last year I have a Korallin reaktor that I have...

thx

Are there any possible creature that graze on mushrooms (Discosoma/Rhodactis)? I have a tank with many beloved SPS, but have constantly problems by mushrooms burning the SPS. I have tried many times to destroy them by hot kalkwasser, and scissors, but I estimate them to be thousands... (and...

I really likes that thread, but my question was never answered :cry: Better luck this time.. :D My questions are: How is the phosphate stored in the sand bed? As detritus? As larger organisms? Bound to the calciumsubstrate? And in what proportions? I want to know how to handle my (3 year...

I hade a black sea cucumber that died (after about a year), all fishes (except one Am. occellaris) died within two hours even though I came home, saw all fishes alive but noticed that something was wrong, added an extra skimmer and more carbon. The peak was over same night. All invertebrates...

The P-buildup in the DSB. How is the P stored? 1. chemically bonded to the CaCO3 (like P-remover material)? 2. incuded in detritus (=bacteria mostly?)? 3. included in higher lifeforms? Probably all of them, or? The reason I ask is that after having a successful (OK, in my opimion successful)...

Thanks Maiden, I read that thread, but my initial questions remains. Only one chemical formula was presented (4 NO3 + 3 S = 2 N2 + 3 SO4), and that formula does not show how pH are lowered. The thread does not say anything about the capacity of the calcium reactor part of the denitrator. /Klas

I resently read about a denitrifying "filter" that included sulphur balls (as denitrificator made by aquacare, www.aquacare.de). This "filter" had som more sulphur balls than recommended by aquacare, and this should lead to a significant lowering of the pH (due to the biological life amongs the...

OK thanks, I have missed the fact that one mole of carbonate provides two moles of alkalinity. And yes, in that case it is pretty close... Other measurements showed even closer to a factor two. /Klas

Ca-addition through a calcium reactor is supposed to be “balanced”. That would mean that the same amount of carbonate are added as calcium. If I meassure the outcome of my reactor and make some calculations this does not seem to be correct. Please help me. Either my calculations or my assumption...
