Ok so I figured out what I was doing wrong. When it says you flip the syringe over and take the reading, I was still reading it like the red sea kit, instead of reading from the tip to the plunger. So when I was reading 7.2 titrant used, it was actually 2.8.
Thats a huge DUH moment as my tank right now is cloudy as h*ll from adding to much of randys 2 part. My tank right now sits at over 12DKH(the kit doesn't go high enough), and its so cloudy I can't even see in it. Will this over dose hurt anything, or will I wake up to everything dead in my tank? MY PH isn't horrible(sitting at 8.3), so that doesn't worry me, just concerned about the overdose.
Its not a snowflake snow storm, more like how when you add ALK it becomes cloudy until its mixed in.
I would go with a different tank so you have a minimum of 24 inches front to back. You will regret that 18 in no time with the larger tank.
I would also suggest a t5 unit for lighting. With you only needing 36 you could get away with a unit for less then 1/2 what the kessil would cost. Or spend about the same and get a combo unit.
Did you look at sc aquariums at all? You can get them undriled if you wish to add an overflow
Deep blue says they use tempered glass in select models on the 65 gallon description.....they have great prices! Real cheap! I would find a tank,stand package for good savings. I can't find anything that states glass thickness on deep blue. I like soulpatch recommendation on going 24 deep. Regardless if u "need" the extra back or front space, it adds water volume which is always better. Most people's limitations on tanks are width, like mine was. I could not go further out due to wall in a corner, but adding the length gave me greater volume.
Go ecotech radion! Kessil, I looked at, but seems so limited, boring, etc. Mounting options aren't cool. Two xr15 pros are good. Then add the ecotech module for apex. Then ur set.
