Is There A Optimal Alkalinity Level? | Reef2Reef There is no optimal alk level for all reefs and all aquarists There are valid reasons to maintian any alk from 7 to 11 dKH, IMO Higher alk (say, 9-11 dKH) promotes faster coral growth, especially SPS If growth is the main goal, higher alk is desirable But if nutrients are not high enough to support the higher growth, high alk can risk burnt
Pros and Cons of Alkalinity and Calcium Dosing Methods Because of these last two points, many aquarists combine kalkwasser (for the pH boost) and CaCO3 CO2 reactors (for a big amount of alk and calcium) in high demand systems
Low alkalinity, safe way to raise it? | Reef2Reef Figured I’ll raise it to 6 ml’s a day and try to raise the alk level 1- 2 points a day good plan or just keep it where it is? Or perhaps another method or strategy? Like maybe starting kalkwasser along with all-for-reef for ph boost or would that raise it to much? Other levels are seemingly corresponding with Alk , Calcium 385, Magnesium
What is the ideal alkalinity | Reef2Reef In my experience, SPS polyp estension is greater (i would even say crazy polyp ex) with Alk level between 7-8 Alk above 8 and polyps dont extend so much But my usual Alk range fluctuates between 7-7 8 My No3 i keep between 3-6 When my parameters are stable, my corals start growing fairly quickly But as we all know, some corals grow faster and some slower
HOW CAN I QUICKLY LOWER ALKALINITY? | Reef2Reef You risk burnt tips at higher alk and low nutrients, but the paleness is more likely from just the low nutrients alone I'd personally dose nutrients or feed more and let alk slowly fall, rather than solve only part of the problem by lowering alk fast To lower alk, IMO, it is a better plan to lower the alk in water change water using any mix you want (can lower to zero if you want), than to
Alkalinity Calcium dosing and consumption | Reef2Reef Alk I test with hanna and cross check with red sea alk and gives me a precise value to measure consumption on brs website, Good point I just checked my water with both Triton and ATI and calcium tested out with them at 450 whereas my Red Sea test came in at 400
2 part dosing | Reef2Reef Most two-part calcium and alk supplements are designed so that dosing equal amounts will maintain the balance of ions in your system You're basically adding calcium chloride (the calcium part) plus sodium carbonate or sodium bicarbonate (the alk part), so the calcium and the carbonate become available to your coral in the same ratio that they normally uptake from the water to build their
Alkalinity decline without coral | Reef2Reef Alk is consumed by many biological processes in a tank other than coral Younger tanks can consume alk at an astonishing rate as their biology gets established I've had young tanks drop 2 points of dKH a day for months as bacteria beds get established No corals Get a diatom bloom? Watch your alk plummet as the carbon is used as building blocks
Best alkalinity for mixed reef being sps dominant | Reef2Reef I looking to see where everyone runs there alk calcium in there mixed to mostly sps reefs I use coral pro salt and my parameters are right around 10 5-11dkh and 460-480 in calcium Should I be around 8-9dkh 420-440 for color and growth? And help would be great
Alkalinity rising without dosing. . . possible causes? | Reef2Reef The rising alk got to be such a problem that I needed to do water changes with artificially lowered alk (using muriatic acid) to keep it from rising to dangerous levels So I'd do several 10% water changes with new saltwater with 5dkH over several days to slowly bring it down
