Crushed Coral Depth?
I have had my SW tank for 9 months and have been adding live rock (now 52lbs in a 55 gal tank). Reading your web site and others this past week I became concerned that my 55 lbs (Carib Sea, Florida, 5-10 mm) crushed coral substrate was too thick (approx 1.5 – 2 inches) – I am not using an UGF and the articles mentioned to keep the substrate to 0.5 – 0.75 inches in this case as it mentioned a couple of gases that can develop that are toxic to the inhabitants (fish and corals). This morning I read an article on your site that encouraged a thick bed (see excerpt below): Substrate question I have about a 2.5 inch bed of crush coral in my 55 gallon tank. I want to add another inch of Flamingo Pink on top of the crush coral, is this OK or will it kill a lot of my biological in my crushed coral? Also would the Flamingo Pink be ok with gobies (stirrers). Thanks, Jim >> Should be okay… density, size wise of the new/old substrates… with the gobies as well… but will the two mixing together
